Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• With IGMP snooping enabled, the system does not learn router ports from IGMP membership
queries. This problem is resolved in Release 12.1(13)E. (CSCdx39149)
• When the MSFC is the IGMP querier on a Layer 3 interface and it receives a topology change
notification (TCN), the MSFC does not send the required general queries when only IGMP is
enabled. The MSFC sends the two general queries, spaced 10 seconds apart, only if CGMP is
enabled. This problem is resolved in Release 12.1(13)E. (CSCdx42565)
• Slowly inserting or removing a module might freeze the system in a switching bus stall. This
problem is resolved in Release 12.1(13)E. (CSCdy19226)
• If you enter the no mls qos command to disable QoS on a Layer 2 port that is configured for
VLAN-based QoS with the mls qos vlan-based command, any policies applied to the port’s VLAN
continue to be applied to traffic coming from the port. This problem is resolved in
Release 12.1(13)E. (CSCdy26824)
• With a PFC2 and with DFCs, you cannot configure Layer 2 EtherChannels that include interfaces
on different DFC-equipped switching modules. This problem is resolved in Release 12.1(13)E.
(CSCdt27074)
• If you enter the do command under the interface range command, Cisco IOS executes the do
command for each interface in the range. This problem is resolved in Release 12.1(13)E.
(CSCdw92111)
• In a system that has policing configured and a Switch Fabric Module installed, the “AgId” field is
reset to zero in the display after an OIR of a Switch Fabric Module, and the counters may not show
packets that are policed. This problem is resolved in Release 12.1(13)E. (CSCdy19696)
• You cannot configure a port on a fabric-enabled switching module as a SPAN source port. This
problem is resolved in Release 12.1(13)E. (CSCdw74764)
• Because of a lack of IPC buffer space, a system with a Supervisor Engine 1 and an MSFC2 might
reload when ICC messages are waiting in the queue. Before the system reloads, messages of the
following type may appear:
%ICC-SP-5-WATERMARK:5988 pkts for class L3-MGR are waiting to be processed
%IPC-SP-3-NOBUFF:The main IPC message header cache has emptied
This problem is resolved in Release 12.1(13)E. (CSCdw53279, CSCdx05096)
• IP connectivity to the supervisor engine Gigabit Ethernet ports does not work in Releases
12.1(11b)E and 12.1(11b)E1. This problem is resolved in Release 12.1(13)E. (CSCdx04363)
• With loose Unicast RPF configured on the MSFC, traffic that should be dropped is still forwarded
through the MSFC. This problem is resolved in Release 12.1(13)E. (CSCdw92775)
• 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 in the other direction, 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(13)E. (CSCdw55635)
• If you enter the do command under the interface range command, Cisco IOS executes the do
command for each interface in the range. This problem is resolved in Release 12.1(13)E.
(CSCdw92111)
• To avoid unreliable operation, do not enter the do command in EXEC mode. This problem is
resolved in Release 12.1(13)E. (CSCdx02925)
