The following features are not supported on a Catalyst 4500-X Series switches:
With some exceptions, the VSS maintains “feature parity” with the standalone Catalyst 4500 or 4500-X series switches. Major exceptions include:
This section describes the new and changed information for the Catalyst 4500-X Series switch running Cisco IOS XE software:
10/ 100 Mbps support for GLC-T (1000Base-T) SFP transceiver. You can set the interface speed to 10 or 100, by using the speed interface configuration command. The default setting provides 1000 Mbps with auto-negotiation. |
|
Support for Cisco Plug-in for OpenFlow (Cisco Plug-in for OpenFlow, Version 2.0.0) provides better control over networks making them more open, programmable, and application-aware. The Cisco plug-in supports a subset of OpenFlow 1.3 and OpenFlow 1.0 functions. For the list of supported functions and configuration information, see the Cisco Plug-in for OpenFlow Configuration Guide for Catalyst 4500 Series Switches. For compatibility information, see OpenFlow Version and Cisco IOS Release Support. |
|
Support for Cisco TrustSec (CTS) fields, to monitor and troubleshoot the CTS network, and to segregate traffic based on source group tag (SGT) values. |
|
Support for forwarding GRE tunneled packets on the switch hardware. |
|
Support for the new lacp rate command, to set the rate at which Link Aggregation Control Protocol (LACP) packets are sent to LACP-supported interfaces.You can change the timeout rate from30 seconds (default rate) to 1 second (fast rate). |
|
Support for point-to-point protocol tunneling of LACP and PAgP protocols. |
|
Support for Layer 2 tunneling of the UDLD protocol. This can be used in conjunction with the LACP or PAgP point-to-point tunneling or by itself, for unidirectional tunnel detection. |
|
Support for Object Group ACLs (OGACLs), to group ACE entries, and add or remove entries, while keeping your ACL structure more readable. |
|
Support for MAC address filtering.You can prevent the switch from learning specific MAC addresses, by forbidding the MAC addresses on all interfaces, globally, or on a specific port-security enabled interface. |
|
Support for VRF copy commands. You can specify a VRF, for copy commands (FTP, TFTP, SCP etc.), when copying files to and from the switch. |

URL for the Cisco IOS XE Release 3.7.0E Documentation Roadmap provides quick and easy access to all relevant documentation for specific platforms. Look for Quick Links to Platform Documentation on the respective platform documentation pages. For more information, see http://www.cisco.com/c/en/us/support/ios-nx-os-software/ios-xe-3e/tsd-products-support-series-home.html.
The following table list the new features for Release IOS XE 3.7.0E:
As Table 7 shows, each version of Cisco IOS XE has an associated Cisco IOS version:
If you are upgrading to IOS XE Version 3.7.0E and plan to use VSS, you must upgrade your ROMMON to IOS Version 15.0(1r)SG11.
ISSU is supported on 4500X in VSS configuration.
If dual supervisor engines are present, first upgrade your software to Cisco IOS XE 3.2.0SG or later, then upgrade your ROMMON to IOS Version 15.0(1r)SG7 to avoid an uplinks issue (CSCtj54375).
Workaround : You have to enter the shutdown and then the no shutdown interface configuration command for traffic flow to resume. (CSCus14532)
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.
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:
Workaround: Define a policy-map with a different name and then reattach. CSCti26172
– Decrease the number of monitors.
– Attach the same monitor to multiple targets. CSCti43798
Workaround: Use the dir device command (for example, dir bootflash:) to obtain the correct file count. CSCti74130
– 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.
You cannot clear a large number of mroutes at one time when traffic is still running.
Workaround: Do not clear all mroutes at once.
Workaround: Use the show version command. CSCtr30294
Workaround: Select an alternate destination or source port. CSCty05405
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
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
This applies to QoS policing only. QoS marking, shaping and sharing behave as expected.
Workaround: Apply FHS policies on a non EtherChannel port rather than a VLAN. CSCua53148
Because the Catalyst 4500-X is a “fixed” configuration device, in a VSS, you would expect the two systems to be labeled 'Module 1' and 'Module 2.’ However, because of software implementation similarities with the modular Catalyst 4500E series switches, the Standby switch is labeled 'Module 11.’
Workaround: None. QoS groups are not supported in VSS. CSCuc84739
These messages are cosmetic only, and no ssh services are available unless configured within IOS.
Caveats describe unexpected behavior in Cisco IOS releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.
