http://www.cisco.com/en/US/docs/routers/access/interfaces/nm/hardware/installation/guide/satnm.html
USB eToken 64KB smartcard support
The Cisco universal serial bus (USB) eToken 64KB smartcard support feature enables device authentication and simplifies the deployment and secure configuration of Cisco routers. It uses smart card technology in a USB form factor to facilitate the authentication and configuration process. The token provides secure access to the route. The token and a PIN are necessary to access the configuration, keys, and credentials.
Some Cisco access router models have USB ports that can be used with Cisco USB flash memory modules or with the Aladdin USB eToken Pro key. These USB modules can be used with a supported Cisco access router for the following functions:
•USB eToken Pro key provides a secure means of storing and deploying information, such as a bootstrap configuration or VPN credentials, apart from the router chassis. The USB eToken uses smart card technology to protect a small area of memory.
•The USB eToken grants access using a personal identification number (PIN). When IP Security (IPSec) VPN credentials are stored on the USB eToken, they are outside the router. When the USB eToken is inserted in a USB port, and when the user enters the PIN and unlocks the USB eToken, the user retrieves the credentials and copies them into running memory. When the USB eToken is removed, the router erases the credentials from running memory, ensuring that they cannot be retrieved from the router itself.
For more information, see:
http://www.cisco.com/en/US/prod/collateral/modules/ps6247/prod_qas0900aecd80232483.html
USB Boot Feature
The USB Boot feature supports booting from ROMMON and IOS. Platforms can boot from USB in ROM monitor with or without a compact flash device. It is not necessary to use a bootloader image from the compact flash device. Partitions, such as usbflash0:2:image_name, are not supported on USB flash drives.
For more information on this feature, see:
http://www.cisco.com/en/US/prod/collateral/modules/ps6247/prod_qas0900aecd80232483.html
New Hardware Features in Release 12.4(11)XJ
The following new hardware feature is supported in this release:
•HWIC and VLAN Feature Enhancements
HWIC and VLAN Feature Enhancements
The Cisco Fast Ethernet HWICs are single-wide interface cards, available as a 1-port HWIC (HWIC-1FE) and as a 2-port HWIC (HWIC-2FE), that provide Cisco modular and integrated services routers with additional line-rate Layer 3 routed ports. The following enhancements have been made in Cisco IOS Release 12.4(11)XJ:
•Extended VLAN ID
•HWIC-1FE Routed Port
•HWIC one FE and two FE ports
For more information about these features, see:
•Installing Interface Cards in Cisco 2800 Series Routers http://www.cisco.com/en/US/docs/routers/access/2800/hardware/installation/guide/09_hw.html
•Cisco Network Modules and Interface Cards Regulatory Compliance and Safety Information
New Software Features in Release 12.4(11)XJ
The following new features are supported in this release:
•HWIC-4SHDSL, HWIC-2SHDSL Support
•VRF-Aware H.323 and SIP for Voice Gateways
ADSL2/2+ Annex M Support
The asymmetric digital subscriber line (ADSL) 2/2+ Annex M feature supports routed bridge encapsulation over VC bundles on specific platforms in Cisco IOS Release 12.4(11)XJ. (ADSL) 2/2+ Annex M supports an upstream data rate of up to 3 Mbps and a downstream data rate of up to 24 Mbps. The increase of the Annex M (upstream) data rate is achieved by using some of the tones that were previously used in the downstream data rate in Annex A. As a result, downstream data rates are decreased in Annex M.
The ADSL training log generation command, dsl-enable-training-log, is enhanced to specify the time when to capture a log file. This enables the training log to record firmware debug messages.
HWIC-4SHDSL, HWIC-2SHDSL Support
The G.SHDSL HWICs support up to four pairs of digital subscriber lines (DSL): two inverse multiplexing over ATM (IMA) lines, and two ATM segmentation and reassembly (SAR) lines. The four DSL pairs are bundled in groups and configured in the Cisco IOS command-line interface (CLI) by using the dsl-group command.
•The HWIC-2SHDSL provides two ports of connectivity through one RJ-11 connector. It supports 1-Pair groups or 2-Pair groups.
•The HWIC-4SHDSL provides four ports of connectivity through one RJ-45 connector. It combines four ports of data into one line or two lines with either inverse multiplexing over ATM (IMA) groups or M-pair groups, and it supports 1-Pair groups or 2-Pair groups.
VRF-Aware H.323 and SIP for Voice Gateways
VPN routing and forwarding (VRF) divides a physical router into multiple logical routers, each having its own set of interfaces and routing and forwarding tables. Adding VRF-awareness to voice gateways allows a voice gateway to exist in the same router as a customer edge (CE) or provider edge (PE) WAN router.
The VRF-Aware H.323 and SIP for Voice Gateways feature adds single voice VRF support to Session-Initiated Protocol (SIP), H.323, and IP-to-IP gateways and to Cisco Survivable Remote Site Telephony routers. For more information, see:
http://www.cisco.com/en/US/docs/ios/12_4t/12_4t15/vrfawvgw.html
Wireless LAN Features
The following features are supported on the wireless LAN (WLAN).
Access Point Link Role Flexibility
Access Point Link Role Flexibility allows access point radios to operate in a combination of radio roles, such as access point root, bridge root (with or without clients), bridge nonroot (with or without clients). This provides a more flexible deployment scheme to support the various applications requirement. The ISR AP does not support access point repeater and WGB.
Advanced Encryption Standard (AES) - CCMP
This feature supports Wi-Fi Protected Access (WPA2) which is the Wi-Fi Alliance specification for interoperable wireless LAN security that supports IEEE 802.11i authentication and AES-CCMP encryption.
Extensible Authentication Protocol
Extensible Authentication Protocol (EAP) is an authentication protocol for the 802.1X framework for mutual authentication between the client and a RADIUS server. New EAP authentication types supported in this IOS release include EAP-TTLS, EAP-MD5, and EAP-SIM.
IEEE 802.1X Local Authentication Service for EAP-FAST
This feature allows an IEEE 802.1X enabled RADIUS Server supporting EAP-FAST authentication types to run on Cisco IOS Software, thereby allowing the access point to authenticate wireless clients when the WAN link is down or the RADIUS Server at the central site is not available.
Microsoft WPS IE SSIDL
SSIDL Information Element support.
Multiple Basic Service Set ID (BSSID)
This feature permits a single AP to appear to the WLAN as multiple virtual APs. It does this by assigning an AP with multiple Basic Service Set IDs (BSSIDs) or MAC address. The AP is able to use a different BSSID to advertise each SSID and is therefore able to appear to WLAN clients as if there are multiple physical APs. Each BSSID/SSID combination advertised by the AP is able to be configured to support encrypted or unencrypted traffic.
NAC - L2 IEEE 802.1x
Network Admission Control (NAC) L2 IEEE 802.1x extends NAC support to layer 2 switches and wireless access points. Combining it with 802.1x provides a unified authentication and posture validation mechanism at the layer 2 network edge. This helps protect the network from attack by machines with insufficient antivirus posture. Performing posture validation at the edge maximizes the portion of the network which is protected and allows posture validation to be performed within a VLAN.
Universal Client Mode
This feature allows the access point radio to act as a client to another Cisco or Third-party access point. See caveats for known issues.
VLAN Assignment By Name
This feature provides the ability for the RADIUS server to assign an 802.11 client to a VLAN identified by NAME. Prior to the introduction of this feature, VLANs had to be identified by "VLAN_ID".
Wi-Fi Multimedia (WMM) Required Elements
This feature supports WMM which is the Wi-Fi Alliance specification for QOS.
Wireless NonRoot Bridge
The wireless non-root bridge allows the access point radio to operate as the remote node in a point to point or point to multi-point network. See caveats for information on antenna support.
Wireless Root Bridge
The wireless root bridge role provides support for both point-to-point or point to multipoint bridging. See caveats for information on antenna support.

Miscellaneous Caveats
•CSCse56501
A device running Cisco IOS software that has Internet Protocol version 6 (IPv6) enabled may be subject to a denial of service (DoS) attack. For the device to be affected by this vulnerability the device also has to have certain Internet Protocol version 4 (IPv4) User Datagram Protocol (UDP) services enabled. To exploit this vulnerability an offending IPv6 packet must be targeted to the device. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation will prevent the interface from receiving any additional traffic. The only exception is Resource Reservation Protocol (RSVP) service, which if exploited, will cause the device to crash. Only the interface on which the vulnerability was exploited will be affected.
Cisco is providing fixed software to address this issue. There are workarounds available to mitigate the effects of the vulnerability.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml.
•CSCsf12082
Certain Cisco Catalyst 6500 Series and Cisco 7600 Router devices that run branches of Cisco IOS based on 12.2 can be vulnerable to a denial of service vulnerability that can prevent any traffic from entering an affected interface. For a device to be vulnerable, it must be configured for Open Shortest Path First (OSPF) Sham-Link and Multi Protocol Label Switching (MPLS) Virtual Private Networking (VPN). This vulnerability only affects Cisco Catalyst 6500 Series or Catalyst 7600 Series devices with the Supervisor Engine 32 (Sup32), Supervisor Engine 720 (Sup720) or Route Switch Processor 720 (RSP720) modules. The Supervisor 32, Supervisor 720, Supervisor 720-3B, Supervisor 720-3BXL, Route Switch Processor 720, Route Switch Processor 720-3C, and Route Switch Processor 720-3CXL are all potentially vulnerable.
OSPF and MPLS VPNs are not enabled by default.

CSCsh14247 Call transfer fails when initiated from SIP PhoneCSCsg49416 Refer is not sent by CME when Cfwd all is set from TNP phoneCSCsh19990 Traceback= 0x438662AC 0x40BF2BEC with Call Park/Pick Up operationCSCsh37345 DSL Operating-mode `auto tone low' enables ETSI mode onlySymptom The DSL line fails to train with "dsl operating-mode auto tone low" command if the DSLAM does not support ETSI mode.
Conditions In the command dsl operating-mode auto tone low, the "dsl operating-mode auto" is used to enable all the supported modes on a DSL line and the "tone low" is used to disable DT-UR2 so that the DSL line can use the carrier tones 29 through 48. Instead, this command does not disable DT-UR2 and enables only ETSI mode. With this,
a. If the DSL configuration on the DSLAM does not support ETSI mode, then the DSL line fails to train up.
b. If the DSLAM supports ADSL2+, ADSL2, ETSI modes, then it trains in ETSI mode, where it's supposed to train in ADSL2+, since the ADSL2+ has higher priority than ETSI mode.
Workaround Avoid using "dsl operating-mode auto" command. To select a desirable mode along with disabling DT-UR2, the commands like "dsl operating-mode adsl2+ tone low" or "dsl operating-mode adsl2 tone low" can be used.
CSCsh11146 Memory leak at AFW_SS_SIP_PrepareTransferSetupSymptom Memory leak occurred in transfer scenarios.

Conditions This problem happens if WIC-1SHDSL-V2 comes up before HWIC-4SHDSL.
1. Shutdown both HWIC-4SHDSL and WIC-1SHDSL-V2.
2. Reload the router. Do a "no shutdown" on HWIC-4SHDSL controller first and then do a "no shut" for WIC-1SHDSL-V2 controller.
3. Then save the config.
CSCsh41397 SNMP getone gives NO_SUCH_INSTANCE_EXCEPTION error for HWIC-4SHDSLSymptom SNMP GET operation on HDSL2-SHDSL-LINE-MIB objects returns no such instance for HWIC-4SHDSL.

CSCsh58082 SIP: A router may reload due to SIP trafficSymptom Cisco devices running an affected version of Internetwork Operating System (IOS) which supports Session Initiation Protocol (SIP) are affected by a vulnerability that may lead to a reload of the device when receiving a specific series of packets destined to port 5060. This issue is compounded by a related bug which allows traffic to TCP 5060 and UDP port 5060 on devices not configured for SIP. There are no known instances of intentional exploitation of this issue. However, Cisco has observed data streams that appear to be unintentionally triggering the vulnerability.
Workaround Workarounds exist to mitigate the effects of this problem on devices which do not require SIP. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20070131-sip.shtml.

CSCse78963 Adopt new default summer-time rules from EPA BADCODE BUGSymptom Starting in calendar year 2007, daylight savings summer-time rules may cause Cisco IOS to generate timestamps (such as in syslog messages) that are off by one hour.
Conditions The Cisco IOS configuration command: clock summer-time zone recurring uses United States standards for daylight savings time rules by default. The Energy Policy Act of 2005 (H.R.6.ENR), Section 110 changes the start date from the first Sunday of April to the second Sunday of March, and it changes the end date from the last Sunday of October to the first Sunday of November.
Workaround A workaround is possible by using the clock summer-time configuration command to manually configure the proper start date and end date for daylight savings time. After the summer-time period for calendar year 2006 is over, one can for example configure: clock summer-time PDT recurring 2 Sun Mar 2:00 1 Sun Nov 2:00 (this example is for the US/Pacific time zone)

CSCsg14313 traceback seen while making conference/transcoder co_exist callsCSCsg57002 SIP timer tree corruption is causing SIP gateway crash under loadSymptom The SIP Gateway will crash when handling calls involving DTMF relay.
Conditions Following is the scenario that is causing the crash: sip-notify and sip-kpml are configured as DTMF relay mechanisms on both Cisco IOS Gateway and CCM. When a call is coming in from CCM onto the GW, because of a bug (CSCse72749), GW negotiates the DTMF mechanism as sip-notify whereas CCM negotiates the DTMF relay mechanism as sip-kpml. Subsequently, CCM sends subscribe request for KPML. GW accepts the KPML subscription and starts the respective KPML timers. Now when the call is terminated, Cisco IOS GW is cleaning up the data structures without stopping the KPML timers since the negotiated DTMF relay on Cisco IOS GW is sip-notify.
Workaround There are two workarounds:
1. Migrate to a Cisco IOS version which has CSCse72749 fix integrated.
2. Enable either sip-notify or sip-kpml on the Cisco IOS GW (do not enable both).

Open Caveats - Release 12.4(11)XJ
There are no open caveats in this release.
Resolved Caveats - Release 12.4(11)XJ
CSCse89321: DTMF path not getting confirmed in sip media forking callSymptom : There is no end-to-end DTMF path confirmation.
Workaround : There is no workaround.
CSCsf26561: User portion of Diversion header is incorrect when calling through AASymptom : Tests on customer setup have revealed that PSTN to AA --> tx to SCCP phone--> CFWD to Cisco Unity Express/PSTN has an issue. The 302 Moved Temporarily from Cisco CallManager Express to BroadSoft has a Diversion header whose user portion is the private extension #, not the expanded DID # because of which the subsequent call fails.
Workaround :Remove the dialplan-pattern.
CSCsf32028: Host portion of Refer-To: header must be an Address of RecordSymptom : SIP trunking environments (for example, Cbeyond) need the URIs to carry Address of Record [AOR] in many SIP headers.
Workaround : There is no workaround.
CSCsg17289: DNS-SRV issues for SIP registrationsSymptom : Registrar, both the dial-peers would try to send a REGISTER request sequentially. When first Dial-peer (D1) is sending REGISTER Request, the registrar cache is empty. It first sends a DNS query (SRV). After getting the DNS Response, it updates the Registrar cache and sends the REGISTER request to Registrar R1. dns_count variable to SIP_DNS_MODE.
When a second dial-peer is sending a REGISTER request, it finds the resolved IP address in registrar cache (R1) so it sends the REGISTER request to R1. dns_count variable to SIP_NON_DNS_MODE. But both the REGISTER request fails because R1 is down.
As D1 is set to SIP_DNS_MODE, D1 would send a DNS query again with incremented dns_count to get any alternate Registrar and it gets R2. It sends REGISTER request to R2 and gets successfully registered. As D2 is set to SIP_NON_DNS_MODE, it does not retry the DNS query and simply backs off for period REG_EXPIRES/20.
Workaround : There is no workaround.
CSCsg18902: Blind transfer is not working on SIP trunkSymptom : Blind transfer failed on SCCP endpoint over SIP trunk
Conditions : When session-target is configured but outbound-proxy is not configured.
Workaround : There is no workaround.
CSCsg30101:CME: dtmf-relay force rtp-nte CLI does not workSymptom : The voice-class sip dtmf-relay force rtp-nte command does not work.
Conditions : Call comes from PSTN gw to CUE-AA, w/offer SDP of g711u, 100(NSE) Cisco CallManager Express invite's the Cisco Unity Express by offering g711u and NOTIFY for DTMF. Cisco Unity Express replies with g711u & NOTIFY for DTMF Cisco CallManager Express replies to the PSTN gw with only g711u codec with the software image.
As a result, rfc2833 is not negotiated and hence DTMF is sent raw inband. When a PSTN caller presses DTMF digits after being prompted by AA, nothing works, because the Cisco CallManager Express cannot convert raw-inband DTMF to NOTIFY. With 12.4-4T3 the Cisco CallManager Express replied to the PSTN gw with g711u and rfc2833(PT=101).
Workaround : There is no workaround.
CSCsg39750: Spurious mem access/traceback while resetting SIP phone with presenceSymptom : Spurious memory access and traceback is encountered while resetting the SIP phone (7961). After configuring presence with CME.BLF speed dial entries, the status is not updated for the watched phones.
Workaround : There is no workaround.
CSCsg46362: Contact header incorrect in 302 message using sip-srst redirect modeSymptom : The contact header ip address is incorrect in the 302 message sent by SIP SRST in redirect mode. As the result basic call fails in this mode. B2b mode is working okay.
Workaround : Use b2b mode.
CSCsg46411 Cisco CallManager Express does not send a REFER over SIP trunk for calls involving AASymptom Cisco CallManager Express fails to send a REFER over the SIP trunk for calls coming into the CUE-AA and being transferred to a local extension.
Conditions The Cisco Unity Express does a BYE-Also transfer and the Cisco CallManager Express is supposed to look at the Also: header and put that into the URI for REFER message.
Workaround There is no workaround.
CSCsg51244 Cisco CallManager Express does not send 3xx messages for transfer --> forward scenariosSymptom Cisco CallManager Express does not send a 3xx message during call fwd if there was a call-transfer invoked before the call-forward happens.
Conditions With only no suppl service sip refer configured on Cisco CallManager Express at the global level, we do not see the Cisco CallManager Express sending a 3xx over the SIP trunk to BSFT. Instead, a wrong reINVITE (only g711u, no dynamic payload 101) is seen when the call is forwarded to B's mailbox. This could potentially cause DTMF issues for a PSTN caller. For PSTN to extension-A(DID #) CFNA to A's voicemail, the Cisco CallManager Express does send a 3xx as expected. Therefore, when a transfer is done before a forward to voicemail happens, the Cisco CallManager Express does not send a 3xx.
Workaround There is no workaround.
CSCsg51259 DTMF stops working after consult transfer to called party mailboxSymptom PSTN connects to extension A, A transfers to B, B's Cisco Unity Express voicemail answers because of CFNA, A does a full consult transfer to B's Cisco Unity Express voicemail.
Conditions The call goes through fine, and the caller can leave a message for B, but DTMF fails even if signaling shows that 101 payload was negotiated for the SIP trunk. So if the caller wants to rerecord or mark the message urgent, it does not work, although the message gets recorded.
Workaround There is no workaround.
CSCek61666 Ephone DNs get stuck in SEIZE state under certain conditionsSymptom Ephone DNs gets stuck in seize state under certain conditions, particularly under the following sequence:
1. phone-A has multiple trunk-DNs configured.2. Call comes in on one of trunk-DN, say DN1. Call is answered and thetransfer button is pressed and another extension (DN3) is dialed.The dialed extension answers the call.3. At this time, the user on phone-A goes offhook on another trunk DN(say DN2), and dials one digit.4. The PSTN user who is connected to DN1 hangs up and so does DN3The above sequence gets both channels of DN1 into a SEIZE state.
Conditions The root cause of the issue was narrowed down to trunkdial flag that is part of the skinnyCB structure which is maintained per-phone. So, when DN2 goes offhook, this trunkdial flag is set. When the trunkdial flag in ON, all state transitions in the DN are ignored in SkinnyUpdateCallState. So, all state transitions are ignored for DN1 when the call is being cleared because the trunkdial flag is set for the entire phone rather than the specific DN.
Workaround CSCek61570 resolves this issue in the Cisco IOS Release 12.4(XC) throttle using a mechanism where the state transitions are not ignored it is not the active DN with trunkdial flag still in the skinnyCB structure. Make the trunkdial flag per-DN specific rather than per-phone.
CSCek37305 Cisco 7200 router crashes at get_hwidb_if_sameSymptom Router crashes on unconfiguring T1 controller with interface configured for RTP priority.
Conditions This is seen on 7200 NPE-G1 router loaded with a Cisco IOS Release12.2(31.4.17)SB image
Workaround A workaround is to ensure that the ip rtp priority or ip rtp reserve command is removed before deleting the interface.
CSCek39470 Router memory leak because of pak subblock chunk leaking with crypto+BVISymptom Cisco IOS router running Release12.4 may experience per packet memory leak because of pak subblock leak in Process memPool (not in IO mem pool). The symptom is: show proc mem 1 output seeing the first allocator's memory count keep growing, and never decreasing.
Conditions The leak is observed with BVI (Bridge-group Virtual Interface) interface configured with crypto IPsec tunnels. Specifically when the router is doing decryption, then send the decrypted packet to BVI interface.
Workaround Shutdown any BVI (Bridge-group Virtual Interface) if being used in a router with crypto IPsec configured.
CSCek45272 NAT overload failing with static mappingsSymptom NAT overloading from inside source address to an outside interface may fail.
Conditions The symptom was seen when translation ports were specified in an access-list associated to a route map and a second static NAT translation condition. Traffic which should have been NATed via the primary NAT overload statement failed because of the specified translation ports being used in second NAT translation condition. This occurred although the traffic to be NATed did not meet the conditions of the second static NAT translation condition.
Workaround Remove the ip nat inside source interface X overload statement and then add it again. The AT translations will then work correctly until the next router reload.
CSCek61570 Trunk dn stuck in seize/seize state and does not recoverSymptom The ephone DN may get stuck in SEIZED state and one-way audio would occur afterwards.
Conditions If another call is dropped during trunk dialing, the DN for this terminated call would move to seized state.
Workaround Press the ENDCALL softkey twice to move the seized DN to idle state after finishing the and trunk call. To work around the one-way audio issue, the call needs to be transferred out and then transferred back.
CSCek62099 MLP: PPPoE encap not applied to Cisco Express Forwarding switched nonMLP packetsSymptom When PPP Multilink is enabled over a PPP over Ethernet (PPPoE) session, outbound packets are incorrectly sent without PPPoE headers. This causes them to be dropped.
Conditions Symptom is observed in IOS version 12.4 on all software-forwarding router platforms. It only affects packets which are not multilink encapsulated (due to the bundle only having a single link).
Workaround Either disable multilink PPP, or use the ppp multilink fragment delay interface command to force multilink headers to be applied to all outbound packets.
CSCir00074 Router crashes when casnDisconnect is set to true for pppoe sessionSymptom A router crashes when the casnDisconnect object is set to "true" for a PPPoE session.
Conditions This symptom is observed on a Cisco 10000 series when you attempt to terminate the PPPoE session through SNMP by using the casnDisconnect object of the ISCO-AAA-SESSION-MIB.
Workaround There is no workaround.
CSCir00530 CJ-Ph2:Entry missing in cefcModuleTable for a CJ PA in Escort slotSymptom Entry for Crackerjack PA missing from cefcModuleTable.
Conditions SNMPGet on the table is issued.
Workaround There is no workaround.
CSCsc48536 A router may reload unexpectedly because of bus error at ipnat_lock_natSymptom A Cisco router may reload unexpectedly with a bus error exception.
Conditions This symptom has been observed on a router with Network Address Translation (NAT) enabled.
Workaround There is no workaround.
CSCsd50476 When channel-group configured serial interface goes down, CSCse35510 OER misidentifying overlapping prefixesSymptom A serial link goes down.
Conditions This symptom occurs when a T1/E1 controller that is configured with channel-group causes the serial link to go down. The CEM interface will not come up.
Workaround There is no workaround.
CSCse46648 IP Address Getting Removed From Interface On Deleting Crypto ConfigSymptom IP address removal from a physical interface
Conditions When IPsec connection fails and the ip unnumbered config is applied on the virtual template
Workaround Use cryptomaps, wit vtis, to configure the IP address on the physical interface and reattempt connection.
CSCse88584 Router proposes the default ISKMP policy if configured one does not matchSymptom Router is proposing the default ISAKMP policy if the configured one does not match
Workaround There is no workaround.
CSCsf16536 IOSIPS - router crashes at tw_timer_start with sig action denyFlowInlineSymptom A Cisco IOS router may experience an unexpected reload.
Conditions : This problem occurs when the router has IPS (Intrusion Prevention Systems) configured, and one or more attack signatures has the denyFlowInline action enabled.
Workaround : Do not enable the denyFlowInline action for any IPS signatures.
CSCsf27796: Cisco 1841 router reloads at retparticle with%SYS-2-BADSHARE errorSymptom A Cisco1841 router may reload at retparticle with%SYS-2-BADSHARE errors.
Conditions The router must be running crypto traffic using a dialer interface over a GSHDSL interface.
Workaround There is no workaround.
CSCsg02881 MLP: Bandwidth of down MLP group should be sum of member bandwidthsSymptom The bandwidth of a multilink group interface that is down does not reflect the actual bandwidths of the links that are configured as members of the multilink group. In Cisco IOS Release 12.4(8) and later, the multilink interface bandwidth reflects the bandwidth of the last link in the bundle before going down. In earlier versions, the bandwidth is restored to 100000 Kbps.
Conditions This symptom is observed when the multilink interface is down. The bandwidth is correct when the multilink bundle is up.
Workaround There is no workaround.
CSCsg10159 Successive Default route ctrl fails on different link but on same routerSymptom Default route withdrawn message is sent from BR immediately after successful control of default route. And prefix goes to DEFAULT state.
Conditions This only happens if OER system has only one BR and Static Routing Protocol is used. The bug is limited to default route prefix only.
Workaround Use nondefault route prefix.
CSCsg12813 Speech loss after receiving MDCX from PGWSymptom A Cisco AS5400 gateway may change its RTP sequence numbers after receiving a MDCX command. The RTP Stream SSRC is always the same and the Sequence Number seems to be randomly initiated again.
Conditions MGCP receives a modification request from PGW for echo cancellation 3 seconds after the call is established.
Workaround There is no workaround.
CSCsg16186 SCMabort Event crash seen on NPE-G2Symptom System may crash during bootup.
Conditions When PA-MCX-8TE1+ is in the system and 256MB IO Memory is configured.
Workaround Reduce IO memory in the configuration.
Further Problem Description: You should see SCM Abort message in the crash info file.
CSCsg16748 ABR deletes OSPF type 3 LSA after it received max-aged type 2 LSASymptom In the situation ABR has both type 2 LSA and type 1 LSA for a prefix, ABR deletes type 3 LSA if it received max-aged type 2 LSA.
Workaround The workaround is configuring timers lsa arrival and timers throttle lsa all or timers lsa-interval.
CSCsg33172 IPS 5.0: Provide more informational error message XML and namesSymptom A few inconsistent error messages.
Conditions Some SDEE messages are not consistent with SDEE schema.

CSCsg38907 rip - redistribute static: redistributed prefixes have metric 16Symptom Under some conditions redistributed static routes are sent out with metric 16.
Conditions The static route for a subnet of a classfull network has a next-hop in another classfull network that is not enabled under rip. The rip update is sent out to a subnet within the same major network that the prefix of the static is about
Workaround Enable the next-hop network under rip. Configure distribute-list to filter the update.
CSCsg39216 ezvpn tunnel traffic with acl keyword is not excluded from NATSymptom When the EZVPN client is configured with "acl" keyword, the tunneled (vpn) traffic also gets NATed.
Conditions This only happens if there is a NAT configuration that includes the interesting VPN traffic. The tunneled traffic should be bypassed from NAT when the VPN is up.
Example:
crypto ipsec client ezvpn hwclientconnect autogroup cisco key cisco123mode network-extensionpeer 10.1.1.1acl 103access-list 103 permit ip 192.168.100.0 0.0.0.255 192.168.1.0 0.0.0.255
This occurs when the following is true:
1) EZVPN client is configured
2) Interesting tunnel traffic is defined using the "acl" keyword under global ezvpn configuration
3) NAT is configured
Workaround Use crypto ipsec ezvpn client <ezvpn-name> inside on the interface instead of the acl keyword under ezvpn global configuration.
CSCsg39961 Crash sending pki request to CA CSCsg43460 Improve NPE-G2 ENVM handlingSymptom A router may unexpectedly reload when trying to send a PKI request to a CA.
Conditions The router must be configured with crpyto PKI trustpoints.
Workaround Because this is a 1 byte redzone overrun, the following will prevent the crashes, and will display error messages instead. First, to prevent the usage of chunks, configure no memory lite. Second, configure exception memory ignore overflow processor to correct the redzone overrun.
CSCsg46546 Erroneous alerting during pickup with CSCek58324 scenarioSymptom Pickup will result in alerting from the pickup target instead of connected.
Conditions Two calls come into a trunk monitor dn. The first one to come in is answered. The second one is then answered on the same phone using the line button. Another phone uses the pickup softkey to dial the first incoming call, which is now on hold.
Workaround This issue only appears to occur on the second scenario of the above after a router reload.
CSCsg47834 NACK is observed for Open voice channel commandSymptom NACK message may be received from 5510 DSP in response to Open Voice Channel command sent by the Cisco IOS software.
2568288: Oct 24 13:11:33.240: //-1/xxxxxxxxxxxx/HPI/[]/hpi_tx_global_debug_info:DSP 3/0x3 port INVALID_CHANNEL_STATE(85), info 0x01(1)DSP 3/0x00000003 port mode CLOSED(1), state UNDEFINED(133), NACKed message 74/0x4A @0DSP message header 0008 0003 004A 0001 Payload: 0x0000 0x0000 0xFFFF 0x0000Conditions This problem may be observed when a same 5510 DSP is used as a Transcoding and Voice Termination resource.
Workaround
1) Disable Transcoding
(or)
2) Make sure that the Transcoding and Voice Termination are on different DSP(s).
This can be performed by configuring the maximum number of transcoding sessions to a value such that it would require a multiple of 240 DSP credits.
Example 1:
In the following configuration each transcoding session (complexity=high) will require 40 DSP credits. In order to use a multiple of 240 credits, we need to set the maximum transcoding sessions to 6 (6 * 40 = 240) or any multiple of 6.
dspfarm profile 1 transcodecodec g711ulawcodec g729r8associate application SCCPRouter(conf-t)#dspfarm profile 1 transcodeRouter(config-dspfarm-profile)#maximum sessions 6Example 2:
In the following configuration each transcoding session (complexity=medium) will require 30 DSP credits. In order to use a multiple of 240 credits, we need to set the maximum transcoding sessions to 8 (8 * 30 = 240) or any multiple of 8.
dspfarm profile 2 transcodecodec g711ulawcodec g711alawcodec g729ar8codec g729abr8associate application SCCPRouter(conf-t)#dspfarm profile 2 transcodeRouter(config-dspfarm-profile)#maximum sessions 8Use the show voice dsp group all command to verify DSP resource allocation.
Each 5510 DSP has 240 Credits. This workaround cannot be implemented if the router has only one PVDM2-16 which has only one DSP.
CSCsg48183 Unforeseen ARP request send from all interfacesSymptom A router may unexpectedly send an ARP request from all its active interfaces to the nexthop of the network of an SNMP server.
Conditions This symptom is observed on a Cisco router that has the snmp-server host command enabled after any of the following actions occur:
–Reload the router.
–A switchover of the active RP occurs.
–Enter the redundancy force-switchover main-cpu command.
Workaround There is no workaround.
CSCsg57228 IPS5.0: c871 reloads using IOS-S222 package fileSymptom Router crashes loading the Cisco IOS signature package file
Conditions Appeared to happen the most on the Cisco 871 and Cisco 2600 platforms.
Workaround There is no workaround.
CSCsg68199 Trunk DN offhook is not propagated to a phone already in dial out modeSymptom Two IP Phones A and B are registered with Cisco CallManager Express; these phones share two trunk DNs 1 & 2. Phone-A goes offhook on DN-1 and Phone-B immediately goes offhook on DN-2. This condition should show the DN-2 button on Phone-A as busy which is not happening.
Conditions This happens only when trunk DNs are used and they go offhook in quick succession on different phones and are in dialing mode.
Workaround There is no workaround.
CSCsg68711 Incoming call in background does not audibly ring after transfer commitSymptom Phone does not ring for the second incoming call after committing transfer alert for the first call.
Conditions While transferring a trunk DN call, a call comes in. After committing the transfer alert, the incoming call still does not ring on the phone.
Workaround There is no workaround.
CSCsg70221 DTMF through the hairpin of a trunk DN does not workSymptom DTMF tones are being suppressed to prevent duplicate DTMF tones from being extended to an SCCP controlled VG 224 port. This problem is a direct result of a fix implemented to correct CSCsf98754. The lack of DTMF prevents IVR devices from working correctly.
Conditions PSTN -- FXO --- CME GATEWAY --- VG224/FXS --- IVR
A call comes into a FXO port that is part of a trunk group and gets transferred to an extension that is hanging off of a VG 224. DTMF is not relayed to the endpoint
Workaround Set the transfer system to full blind to prevent the blocking of the DTMF.
CSCsg70355 Adopt new default summer-time rules from Energy Policy Act of 2005Symptom Starting in calendar year 2007, daylight savings summer-time rules may cause Cisco IOS to generate timestamps (such as in syslog messages) that are off by one hour.
Conditions The Cisco IOS configuration command, clock summer-time zone recurring, uses United States standards for daylight savings time rules by default. The Energy Policy Act of 2005 (H.R.6.ENR), Section 110 changes the start date from the first Sunday of April to the second Sunday of March, and it changes the end date from the last Sunday of October to the first Sunday of November.
Workaround A workaround is possible by using the clock summer-time configuration command to manually configure the proper start date and end date for daylight savings time. After the summer-time period for calendar year 2006 is over, one can for example configure:
clock summer-time PDT recurring 2 Sun Mar 2:00 1 Sun Nov 2:00(this example is for the US/Pacific time zone)
CSCsg73806 Runaway debugs: AFW_Module_ObjectCount pCallIndSsSymptom A router may display the following message to the console repeatedly:
AFW_Module_ObjectCount pCallIndSs 1This is a cosmetic error. With the fix, this message will only be seen with debugs enabled.
Conditions This is seen on voice routers.
Workaround There is no workaround.
CSCsg78801 4.x MinHits or 5.0 event-count not summarizing correctlySymptom Min hit or event count not resetting correctly
Conditions Will fire signature on 1st occurrence of event, but never resets correctly so may or may not continue to fire signature.
Workaround There is no workaround.
CSCsg90212 VSA: Add code to handle CRNG failure interruptSymptom When VSA encounters a Continual RNG failure, the IOS will print the message
VSA encountered CRNG failureWorkaround There is no workaround.
