Release Notes

Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.3.xSG

OL-26675-02

Caveats

• When a switchover is created on the Mediatrace responder, the dynamic access list created for a

monitored flow tuple is not deleted. Although the Mediatrace initiator creates another set of dynamic

access lists after the switchover, the old ones remain in the configuration.

The impact of stale dynamic access lists is to monitor unwanted traffic.

Workarounds:

–

If the switchover is scheduled, remove the scheduled session on the initiator. Reschedule the

session after the new active supervisor engine boots on the responder.

–

If the Mediatrace responder SSO is not planned, after the new active supervisor engine boots,

manually delete the stale dynamic access lists. CSCty75070

• Configuring an interface as unidirectional with the unidirectional send-only | receive-only

command still allows the interface to send (configured as Send-only Unidirection Ethernet mode) or

receive (configured as Receive-only Unidirection Ethernet mode) packets in a bidirectional mode.

Workaround: None. CSCtx95359

• When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps,

ciscoBfdSessUp and ciscoBfdSessDown, are not generated.

Workaround: Do not specify a "bfd" suffix with the snmp-server host x.x.x.x configuration

command. CSCtx51561

• During either a system- or user-initiated reload operation, the following message is observed when

the system shuts down:

HARDWARE WATCHDOG

This message is not observed during a system bootup.

Workaround: None required. This message is information only. CSCtz15738

• A switch running a Supervisor Engine 7-E or Supervisor Engine 7L-E fails if you enter show

memory debug leak on the console while show memory detailed process iosd debug leaks is

being executed from another Telnet session.

Workaround: Avoid running both commands simultaneously. CSCty27680

• If a configuration contains an "ip vrf" or "vrf definition" section, and you type “wr mem” while using

an IP Base or LAN Base boot level of IOS-XE, the following message appears.

Workaround: None. The message is information only. CSCtw93140

• With IGMP snooping enabled, multicast traffic received through a tunnel interface is not forwarded

out the Outgoing Interface List.

Workaround: Disable IGMP snooping. CSCuc65538

• When a port connected to a CDP speaker goes down, a small memory leak occurs (typically less than

300 bytes).

Workaround: Disable CDP on interfaces that may flap frequently. CSCub85948
