Open Caveats in Release 12.1(8b)E20
• Layer 3 hardware-switching support is not available for multicast traffic that needs to be fragmented
and that passes through ingress and egress interfaces which have different MTU sizes. This problem
is resolved in Release 12.1(13)E. (CSCdx95080)
• When you insert an SFM and transition the switching mode to truncated mode, QoS policing and
marking stop working.
Workaround: Remove and then reapply failed policy maps. (CSCeb20536)
Note CSCeb20536 is not observed with later releases.
• If you delete a large number of routes (for example, 150,000), and then add new routes (for example,
800), traffic is not switched to the new routes.
Workaround: Enter the clear ip route * command. This problem is resolved in
Release 12.1(11b)E. (CSCdv58619, CSCeb16290)
• On a Layer 3 EtherChannel, applying an ACL to both the port-channel interface and a member port
prevents the ACL from denying traffic correctly.
Workaround: Remove the ACL from both the port-channel interface and the member port and
reapply it only to the port-channel interface. This problem is resolved in Release 12.1(13)E5.
(CSCdz56987)
• With a PFC2 and DFCs, do not configure SPAN sessions that include interfaces on fabric-enabled
switching modules. This problem is resolved in Release 12.1(11b)E. (CSCds02430)
• If both IOS Server Load Balancing (SLB) and IOS Firewall Load Balancing (FWLB) are configured on
the same router, ICMP packets that need to be firewall load balanced are routed by SLB instead. This
problem is resolved in Release 12.1(12c)E2. (CSCdy18588)
• If you configure more than 16 HSRP group numbers for different VLAN interfaces in a system with
a PFC1, the following error message is displayed:
More than 16 standby groups not supported in this platform.
This problem is resolved in Release 12.1(12c)E1. (CSCdx32496)
• In a system with a Supervisor Engine 1 and an MSFC1, individual Layer 2 aging commands for each
VLAN might be present in the configuration file although only global Layer 2 aging has been
configured. This problem is resolved in Release 12.1(11b)E. (CSCdv21083)
