Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• The output packet counter on a VLAN interface displays incorrect information. This problem is
resolved in Release 12.1(13)E5. (CSCea02680)
• In a topology with routed interfaces, multicast packets may be lost because of incorrect management
of LTL indexes. If you enter a shutdown command followed by a no shutdown command on the
interfaces or perform an OIR of the modules, this problem might occur. This problem is resolved in
Release 12.1(13)E5. (CSCea04508)
• The CAM table might lose a static MAC address entry when multicast MAC addresses and unicast
IP addresses are used in redundant firewalls. This problem is resolved in Release 12.1(13)E5.
(CSCea18561)
• An ACL configured with a “deny udp any any eq 0” ACE blocks noninitial fragmented UDP traffic,
although the noninitial fragment packet does not contain a UDP header. This problem is resolved in
Release 12.1(13)E5. (CSCea27336)
• If the previously active supervisor engine is not automatically rebooted after an RPR+ switchover,
devices may be missing from the ciscoFlashMIB SNMP MIB. This problem is resolved in
Release 12.1(13)E5. (CSCea45559)
• With the RADIUS load balancing feature of Cisco IOS server load balancing (Cisco IOS SLB),
memory corruption and a system reload might occur if you use the replicate casa command or
RADIUS sticky objects for high availability. This problem is resolved in Release 12.1(13)E5.
(CSCea48170)
• With HSRP and EIGRP configured, the system might not be stable with heavy IP Protocol
Independent Multicast (PIM) dense mode traffic. (CSCdz47426)
• To avoid a reload when PIM auto-rendezvous point (AutoRP) or bootstrap router (BSR) is
configured, do not enter the show ip pim rp mapping command. This problem is resolved in
Release 12.1(13)E5. (CSCdy60995)
• To avoid a reload, do not enter the clear ip igmp group command while another user is displaying
the output from the show ip igmp group detail command. This problem is resolved in
Release 12.1(13)E5. (CSCdy72767)
• When the route for a prefix is advertised by both BGP and IGP and the BGP session goes down, the
IGP route for the prefix takes over and LDP allocates and advertises the label for it. When the BGP
session comes up, the LDP session withdraws the label after a 5-minute wait. Traffic is dropped until
the label is withdrawn. This problem is resolved in Release 12.1(13)E5. (CSCdx74321)
• With PIM configured and an (S,G) entry with the F flag reset, a directly connected source might not
start registering when the source becomes active, and the (S,G) state might time out. This problem
is resolved in Release 12.1(13)E5. (CSCdz16276)
• A Multicast Source Discovery Protocol (MSDP) encapsulated packet that receives a type length
value (TLV) with more than one source-active (SA) entry count generates data read errors.
(CSCdz39544)
• Unicast RPF does not work. This problem is resolved in Release 12.1(13)E5. (CSCdz83820)
Resolved General Caveats in Release 12.1(13)E4
• Numerous “EARL-SP-5-EXCESSIVE_INTR” might be displayed. This problem is resolved in
Release 12.1(13)E4. (CSCdz68529)
• Traffic floods incorrectly in a redundant configuration with an EtherChannel configured across both
supervisor engines and across different DFC-equipped modules. This problem is resolved in
Release 12.1(13)E4. (CSCdz54333)
