Current release
IOS XE 3.7.3E—Januray 15, 2016IOS XE 3.7.2E, IOS XE 3.7.1E, IOS XE 3.7.0E
This release note describes the features, modifications, and caveats for the Cisco IOS XE 3.7.0E software on the Catalyst 4500E series switch with Supervisor Engine 7-E, 7L-E, and 8-E.
Note For the Supervisor Engine 8-E to support IOS XE 3.7.0E, the ROMMON version must be upgraded to 15.1(1r)SG5. (Refer to Upgrading the System Software).
Cisco IOS XE 3.7.0E is a feature rich new software feature release for IOS and IOS-XE based Catalyst Access Switching products (Cat4500E/X, 3850/3650, 3K-X, Cat2K and 2K/3K Compact switches) which brings new innovations for Converged Access in wired and wireless topologies, IT Simplicity, Application Experience, and Mobility. This release will provide standard maintenance.
Support for Cisco IOS XE Release 3.7.0E follows the standard Cisco Systems® support policy, available at

http://www.cisco.com//en/US/products/hw/switches/ps4324/index.html
Note Although this release note and those for the Catalyst 4900M, Catalyst 4948E, Catalyst 4948E-F Series Switches, Catalyst 4500 Series Switches, and the Catalyst 4500-X Series Switches differ, each leverages the same Software Configuration Guide, Command Reference Guide, and System Message Guide.
Cisco IOS Software Packaging
The Enterprise Services image supports all Cisco Catalyst 4500E Series software features based on Cisco IOS Software, including enhanced routing.
The IP Base image supports Open Shortest Path First (OSPF) for Routed Access, Enhanced Interior Gateway Routing Protocol (EIGRP) "limited" Stub Rout ing, Nonstop Forwarding/Stateful Switchover (NSF/SSO), and RIPv1/v2. The IP Base image does not support enhanced routing features such as BGP, Intermediate System-to-Intermediate System (IS-IS), Full OSPF, Full Enhanced Interior Gateway Routing Protocol (EIGRP) & Virtual Routing Forwarding (VRF-lite).
The LAN Base image complements the existing IP Base and Enterprise Services images. It is focused on customer access and Layer 2 requirements and therefore many of the IP Base features are not required.
Starting with Cisco IOS Release XE 3.5.0E, OSPF Routed Access in IP Base support rose to 1000 routes.
Cisco XE Release Strategy
Customers with Catalyst 4500 Series Switches who need the latest hardware and software features should migrate to Cisco IOS Release XE 3.7.0E.
IOS XE 3.2.xSG is an active maintenance train that supports Sup7E only. IOS XE 3.4.xSG is a maintenance train supporting Sup7E and Sup7L-E. IOS XE 3.6.xSG is a maintenance train supporting Sup7E, Sup7L-E and Sup8-E. IOS XE 3.6.xE, 3.4.xSG, and 3.2.xSG are extended maintenance (EM) releases. IOS XE 3.5.xE and 3.3.0SG are standard releases (SM).

The following CLI is added under the webauth parameter map:
sleeping-client timeout timeout-in-minutes
– There is one-to-one mapping between device MAC and username/password. Once an entry is added to sleeping-client cache, the device/user gets policies for the user stored in the cache. Therefore, any other user using the device also gets the same policies as the user stored in the sleeping-client cache. The user can force normal authentication by logging out. To do that, the user must explicitly enter the following URL:
– Mobility is not supported. If the client roams from one controller to another, the client undergoes normal authentication on the foreign controller.
Support is added for Control Plane Protection on Wireless (applicable only to Supervisor Engine 8-E)

Table 12 lists the client types on which the tests were conducted. The clients included laptops, handheld devices, phones, and printers.
Important Notes
- Software expand running command is not available. We recommend that you use software expand file command instead.
- Redundancy mode rpr is not available in wireless enabled mode.
- Location keyword to fetch the data from active/active-dc/stby/stby-dc
- Wireless mode shows dc boot status and errors (if any) during boot up.
No configuration is allowed on internal interfaces.
Status/Stats of internal ports are visible under service internal command.
– Supported only in ipbase and entservices license.
– Supported only in install mode.
– Supported only in cat4500es8-universalk9* (Crypto) images
– Requires rommon version 15.1(1r)SG5 or later
– DC bootup logs are stored in bootflash (max 5 files, 1 per reload) with dc_console_log-yyyymmdd-hhmmss-UTC format.
– After DC becomes operational, the logs are forwarded to BB's syslog. DC logs have a prefix of DC-SLOT<slot-no>:
– DC crash info and system reports are stored at crashinfo-dc: and slavecrshinfo-dc: for active-dc and stby-dc respectively
- DC can be disabled in install boot via “hw-module daughtercard disable” configuration. However, you must save the configuration and reload the system for this to take effect.
- AP Joining the WLC:
– A new AP, which has only factory default configurations, sends an L3 Broadcast Discovery message to learn and discover a WLC. Then the WLCs in the broadcast domain respond to this request. This request also has the number of APs they can support and how many APs are currently connected. The AP then would send a Join message to the least loaded WLC among the list.
– When there is an explicit primary WLC IP address configured on the AP, the AP sends a unicast WLC discovery message to this specific WLC. There could also be WLCs that the AP learned about in its past associations with the WLCs and it would send a Unicast Discovery to these WLCs too. After the WLCs respond to this query, it matches with the primary WLC name and IP address and if the match is found, it will join the WLC. If there is an invalid WLC name or IP, then it will not match and it will join the other WLCs that would have responded to the unicast query. If no other WLC responded to the AP, it would send an L3 broadcast discovery message again.
– There is a difference in behavior between how the Sup 8-E based MA or MC handles the Unicast L3 Discovery packet as compared to the Catalyst 3850 Switch in MA or MC mode.
On Catalyst 3850 Switches—Any packet received on the management VLAN is terminated and not forwarded to the unicast IP address in the discovery even if the address does not belong to itself. When a primary base IP of the WLC is configured, the MA does not forward the unicast packets and the AP therefore falls back to sending a broadcast discovery packet which terminates on the Catalyst 3850 Switch.
On Sup 8-E—On the Sup 8-E MA, however, the unicast discovery packet, if received on the management VLAN, is forwarded to the right destination based on the IP address in the discovery packet. Therefore, it reaches the destined WLC and joins it and not the SUP 8-E if the destination IP address is other than the SUP 8-E itself. This results in AP joining the MC and not the MA.
Upgrading the System Software
If you are upgrading to Cisco IOS XE Version 3.7.xE and plan to use VSS, you must upgrade your ROMMON to version 15.0(1r)SG10. Otherwise, you must upgrade your ROMMON to at least Version 15.0(1r)SG2.
For details on how to upgrade ROMMON, refer to:
If you are upgrading to Cisco IOS XE 3.7.xE and using Supervisor Engine 7-E or 7L-E, you must use ROMMON version 15.0(1r)SG10 or a higher version (if available).
If you are upgrading to Cisco IOS XE 3.7.xE and using Supervisor Engine 8-E, you must use ROMMON version 15.1(1r) SG5 or later, version or a higher version (if available).
Note If dual supervisor engines are present, first upgrade your software to Cisco IOS XE 3.2.0SG or higher, then upgrade your ROMMON to version 15.0(1r)SG7 to avoid an uplinks issue (CSCtj54375).
Note When you upgrade to Cisco IOS XE Release 3.7.5E, SSH access is lost, because it cannot use the CISCO_IDEVID_SUDI_LEGACY RSA server key. Before upgrade, generate the server key using the crypto key generate rsa command in global configuration mode. To verify whether the RSA server key is available on your device, run the show crypto key command.
Identifying Hardware Revisions on the Switch Chassis
The Cisco Catalyst 4507R-E Switch chassis that has hardware revision 2.0 or higher supports Supervisor Engine 8-E. Before you install Supervisor Engine 8-E on the Catalyst 4507R-E Switch chassis, enter the show idprom chassis privileged EXEC command on the existing switch chassis to know its current revision number.
The following is a sample output of the show idprom chassis command on a Catalyst 4507R-E Switch. Note the “
Hardware Revision” field here is “2.0”:Upgrading ROMMON Image for Supervisor Engine 8-E
For IOS XE Release 3.7.xE, the ROMMON image must be upgraded to use version 15.1(1r)SG5. The IOS XE Bundle format for Supervisor Engine 8-E has changed, necessitating a new ROMMON image.
The following [error] messages might be observed if IOS XE 3.7.xE images are booted with older ROMMON images:
Identifying an +E Chassis and ROMMON
When supervisor engine 1 (sup1) is in ROMMON and supervisor engine 2 (sup2) is in IOS, only sup2 can read the idprom contents of chassis’ idprom. Chassis type is displayed as “+E” in the output of the show version command. Conversely, sup1 can only display the chassis type as “E.”
When both sup1 and sup2 are in ROMMON, both engines can read the chassis’ idprom. Chassis type is displayed correctly as “+E” in the output of the show version command.
When both sup1 and sup2 are in IOS, both engines can read the chassis’ idprom. Chassis type is displayed correctly as “+E” in the output of the show version command.
Limitations and Restrictions
- If WLAN applied client policy is invalid, the client is excluded with the exclusion reason being 'Client QoS Policy failure'.
- The maximum MTE supported on Catalyst 4500 switches is 8000, per direction.
- Although the show memory command is supported on Catalyst 4500 series switches, the CLI output for the command shows the value 0 for conf ig total, on Catalyst 4500 series switches using a daughter card on Supervisor Engine 7-E. This issue is, however, not seen on switches with Supervisor Engine 7-E baseboard. (CSCup28930)
- The system allows you to delete policy maps related to these Auto QoS profiles:
The problem is seen on a Catalyst 4500 series switch running Cisco IOS-XE release 3.7.0E, when you configure QoS using Auto Qos and you try to delete an Auto QoS profile related policy map.
Workaround : To recover the deleted policy-map, remove all the policies related to that profile, remove Auto QoS configuration from the WLAN, and then reconfigure Auto QoS.
- Dot1x PEAP based authentication for wireless clients on Supervisor Engine 8-E is 3 auths/sec.
- Indirectly connected access points are not supported. Only access points directly connected to a trunk or access port is supported. On connecting more than one AP the following error message will be seen:
3. Dec 5 03:57:24.121: %CAPWAP-3-ONE_AP_PER_PORT: AP (mac:6c20.56a6.4fc4) is not allowed on port:Po2. Only one AP per port is allowed.
- RPR mode cannot be configured when Supervisor Engine 8-E is booted in wireless mode.
- Flow Sampling is not supported on Supervisor Engine 8-E.
- Supported QoS features on wireless targets: The detailed QoS policy is the same as mentioned here: http://www.cisco.com/c/en/us/td/docs/wireless/controller/5700/software/release/3e/qos/configuration_guide/b_qos_3e_5700_cg/b_qos_3e_5700_cg_chapter_011.html#concept_47CC8E2ACA2E44489B9BB7068FCD0649 ), except that the port policy cannot be changed because it is a DC-interconnect port.
- VSS: Do not use SVLAN for routing in SP network on ingress switch (where the mapping is present). This is not an valid scenario.
- VSS is not supported in Wireless mode, on Supervisor Engine 8-E.
- Wired guest access does not work on Supervisor Engine 8-E, in multi-host or multi-authentication mode.
- The show exception files all command lists only crashinfo files from the active supervisor engine. You must issue the dir slavecrashinfo: and dir slvecrashinfo-dc: commands to obtain lists of crashinfo files from the standby supervisor engine.
- Performing an ISSU from a prior release to IOS XE 3.6.0E is not supported.
- The WS-X4712-SFP+E module is not supported in the WS-C4507R-E or WS-C4510R-E chassis and does not boot. This module is supported in the WS-C4503-E, WS-C4506-E, WS-C4507R+E, and WS-C4510R+E chassis.
- More than 16K QoS policies can be configured in software. Only the first 16K are installed in hardware.
- Adjacency learning (through ARP response frames) is restricted to roughly 1000 new adjacencies per second, depending on CPU utilization. This should only impact large networks on the first bootup. After adjacencies are learned they are installed in hardware.
- Multicast fastdrop entries are not created when RPF failure occurs with IPv6 multicast traffic. In a topology where reverse path check failure occurs with IPv6 multicast, this may cause high CPU utilization on the switch.
- The SNMP ceImageFeature object returns a similar feature list for all the three license levels (LAN Base, IP Base, and EntServices). Although the activated feature set for a universal image varies based on the installed feature license, the value displayed by this object is fixed and is not based on the feature license level.
- Standard TFTP implementation limits the maximum size of a file that can be transferred to 32 MB. If ROMMON is used to boot an IOS image that is larger than 32 MB, the TFTP transfer fails at the 65,xxx datagram.
TFTP numbers its datagrams with a 16 bit field, resulting in a maximum of 65,536 datagrams. Because each TFTP datagram is 512 bytes long, the maximum transferable file is 65536 x 512 = 32 MB. If both the TFTP client (ROMMON) and the TFTP server support block number wraparound, no size limitation exists.
Cisco has modified the TFTP client to support block number wraparound. So, if you encounter a transfer failure, use a TFTP server that supports TFTP block number wraparound. Because most implementations of TFTP support block number wraparound, updating the TFTP daemon should fix the issue.
The outputs of certain commands, such as show ip route and show access-lists, contain non-deterministic text. While the output is easily understood, the output text does not contain strings that are consistently output. A general purpose specification file entry is unable to parse all possible output.
While a general purpose specification file entry may not be possible, a specification file entry might be created that returns the desired text by searching for text that is guaranteed to be in the output. If a string is guaranteed to be in the output, it can be used for parsing.
For example, the output of the show ip access-lists SecWiz_Gi3_17_out_ip command is this:
The first line is easily parsed because access list is guaranteed to be in the output:
The remaining lines all contain the term host. As a result, the specification file may report the desired values by specifying that string. For example, this line
will produce the following for the first and second rules
and the following for the third statement
Request the output of the show running-config command using NETCONF and parse that output for the desired strings. This is useful when the desired lines contain nothing in common. For example, the rules in this access list do not contain a common string and the order (three permits, then a deny, then another permit), prevent the spec file entry from using permit as a search string, as in the following example:
The XML output of show running-config command includes the following, which can then be parsed programmatically, as desired:
<X-Interface> permit 0000.0000.ffef ffff.ffff.0000 0000.00af.bcef ffff.ff00.0000 appletalk</X-Interface>
- When attaching a existing policy-map (that is already applied to a control-port) to another front-panel port, the following message displays:
The policymap <policy-map name> is already attached to control-plane and cannot be shared with other targets.Workaround: Define a policy-map with a different name and then reattach. CSCti26172
- If the number of unique FNF monitors attached to target exceeds 2048 (one per target), a switch responds slowly:
– Decrease the number of monitors.
– Attach the same monitor to multiple targets. CSCti43798
- ciscoFlashPartitionFileCount object returns an incorrect file count for bootflash:, usb0:, slot0:, slaveslot0:, slavebootflash:, and slaveusb0:.
Workaround: Use the dir device command (for example, dir bootflash:) to obtain the correct file count. CSCti74130
- If multicast is configured and you make changes to the configuration, Traceback and CPUHOG messages are displayed if the following conditions exist:
– At least 10K groups and roughly 20K mroutes exist.
– IGMP joins with source traffic transit to all the multicast groups.
This is caused by the large number of updates generating SPI messages that must be processed by the CPU to ensure that the platform is updated with the changes in all the entries.
- With traffic running, entering clear ip mroute * with larger number of mroutes and over 6 OIFs will cause Malloc Fail messages to display.
You cannot clear a large number of mroutes at one time when traffic is still running.
Workaround: Do not clear all mroutes at once.
- Although you can configure subsecond PIM query intervals on Catalyst 4500 platforms, such an action represents a compromise between convergence (reaction time) and a number of other factors (number of mroutes, base line of CPU utilization, CPU speed, processing overhead per 1 m-route, etc.). You must account for those factors when configuring subsecond PIM timers. We recommend that you set the PIM query interval to a minimum of 2 seconds. By adjusting the available parameters, you can achieve flawless operation; that is, a top number of multicast routes per given convergence time on a specific setup.
- Energywise WOL is not “waking up” a PC in hibernate or standby mode.
Workaround: Use the show version command. CSCtr30294
Workaround: Select an alternate destination or source port. CSCty05405
– 10/100/1000BaseT Premium POE E Series WS-X4648-RJ45V+E (JAE1348OY52)
– 4 Sup 7-E 10GE (SFP+), 1000BaseX (SFP) WS-X45-SUP7-E (CAT1434L0G4)
the following restrictions apply:
– Sub-interfaces are not supported on 1 Gigabit and Ten-Gigabit interfaces.
– Port-channel members do not support multiple classification criteria for a QoS policy.
– CEF is disabled automatically when uRFP is enabled and TCAM is fully utilized.
- When either the RADIUS-server test feature is enabled or RADIUS-server dead-criteria is configured, and either RADIUS-server deadtime is set to 0 or not configured, the RADIUS-server status is not properly relayed to AAA.
Workaround: Configure both dead-criteria and deadtime.
– Links flap for various Layer 3 protocols.
– A traffic loss of several seconds is observed during the upgrade process.
Workaround: Do not use the quick option with the issu changeversion command. CSCto51562
- While configuring an IPv6 access-list, if you specify hardware statistics as the first statement in v6 access-list mode (i.e. before issuing any other v6 ACE statement), it will not take effect. Similarly, your hardware statistics configuration will be missing from the output of the show running command.
You will not experience this behavior with IPv4 access lists.
Workaround: During IPv6 access-list configuration, configure at least one IPv6 ACE before the "hardware statistics" statement. CSCuc53234
- Routed packets that are fragmented are not policed if the egress interface is on the VSS Standby switch. However, if the egress interface is on the VSS Active switch, these packets are policed.
This applies to QoS policing only. QoS marking, shaping and sharing behave as expected.
- When an IPv6 FHS policy is applied on a VLAN and an EtherChannel port is part of that VLAN, packets received by EtherChannel (from neighbors) are not bridged across the local switch.
Workaround: Apply FHS policies on a non EtherChannel port rather than a VLAN. CSCua53148
- During VSS conversion, the switch intended as the Standby device may require up to 9 minutes to reach an SSO state. The boot up time depends on the configuration and on the number of line cards in the system.
- Dual connectors (like, an SFP+ transceiver inserted into a CVR-X2-SFP10G module) on the WS-X4606-X2-E line card are not supported as a VSL.
Workaround: Use any X2-pluggable module on its own in the WS-X4606-X2-E line card. CSCuc70321
Workaround: Observe the show module command output. CSCua79513
- Beginning with IOS Release XE 3.5.0E, error messages that occur when a QoS policy is applied will no longer appear directly on the console when no logging console is configured. They will appear only when a logging method is active (e.g., logging buffered, logging console, …).
Workaround: None. QoS groups are not supported in VSS. CSCuc84739
- Auto negotiation cannot be disabled on the Fa1 port. It must be set to auto/auto, or fixed speed with duplex auto.
- The following messages are seen during boot up after POST check.
These messages are cosmetic only, and no ssh services are available unless configured within IOS.
- When a logging discriminator is configured and applied to a device, memory leak is seen under heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In extreme cases, the device may crash. As a workaround, disable the logging discriminator on the device (CSCur45606, CSCur28336).
