Caveats
Resolved Caveats in Release 12.1(8b)E10
• If you enter an invalid interface range for the SPAN sources or destinations, the SPAN feature may
not work correctly and the system might reset. Changing the configuration to reflect a valid interface
range corrects this problem. This problem is resolved in Release 12.1(8b)E10. (CSCdv07321,
CSCdv07079)
• Setting the next hop for BGP route reflectors should be allowed only through the outbound
route-map and not through the nexthop-self command. This problem is resolved in
Release 12.1(8b)E10. (CSCdt84706)
• A packet encapsulation error occurs in DLSw. This problem is resolved in Release 12.1(8b)E10.
(CSCdx20546)
• In a PFC2/MSFC2 system with a fabric-enabled 48-port 10/100 Mbps RJ45 module and a
fabric-enabled 16 port 1000 Mbps GBIC module installed, when traffic enters the fabric-enabled
48-port 10/100 Mbps RJ45 and exits through the fabric-enabled 16 port 1000 Mbps GBIC module,
or vice versa, dCEF forwarding is not enabled on the ingress module and traffic is dropped at the
ingress port. This problem is resolved in Release 12.1(8b)E10. (CSCdw55635)
• Configuring protocol filtering on an interface to block IPX, AppleTalk, and other protocols also
blocks egress IP and IPX traffic (ingress IP and IPX traffic is not affected). This problem is resolved
in Release 12.1(8b)E10. (CSCdv23611)
• Enabling IGMP snooping causes multicast packets to be dropped. This problem is resolved in
Release 12.1(8b)E10. (CSCdv24735)
• Partial component failures are not reported and do not trigger switchover in redundant supervisor
engine configurations. This problem is resolved in Release 12.1(8b)E10. (CSCdw31630)
• If a system running Release 12.1(8b)E7 is used in a Server Load Balancing configuration, this error
message may occur:
Jan 13 19:17:08 MET: %ICC-5-WATERMARK: 1123 pkts for class L3-MGMT are waiting t o be
processed
This problem is resolved in Release 12.1(8b)E10. (CSCdw45465)
• The mls aging fast command has no effect. This problem is resolved in Release 12.1(8b)E10.
(CSCdw66953)
• MAC address entries on DFCs do not age out. This problem is resolved in Release 12.1(8b)E10.
(CSCdw76397)
• With IP or IPX ACLs configured on an interface, any incoming IPX packets with source and
destination network numbers set to zero might get dropped on that interface. This problem is
resolved in Release 12.1(8b)E10. (CSCdw76549)
• In a topology where two redundant routers are eligible to be distribution routers for a LAN, a
PIM-SM router may see an interface in its Outgoing Interface List (OIL) with the expiration timer
stuck and the outgoing interface never gets removed. This problem can occur when the backup
distribution router is active, but the failed link from the primary distribution router is restored,
causing the active distribution router status to change to from backup to primary.
Workaround: Enter the clear ip mroute command. This problem is resolved in
Release 12.1(8b)E10. (CSCdw80366)
• The supervisor engine reloads when a write terminal command is entered. This problem is resolved
in Release 12.1(8b)E10. (CSCdw83512)
