Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• When the OSPF cost is changed on one of the upstream paths in the network and a request to delete
or remove the stale entry is not received, the TTFIB table contains stale entries that causes traffic
loss. This problem is resolved in Release 12.1(22)E. (CSCed01611)
• A FlexWAN module is not detected during the boot process causing it to be ignored during the
startup configuration process. This problem is resolved in Release 12.1(22)E. (CSCed00781)
• Directly connected multicast enabled subnets might not be programmed correctly into the PFC. This
problem is resolved in Release 12.1(22)E. (CSCed00394)
• Memory corruption causes the software to reload when an illegal write operation is performed by
the authentication, authorization, and accounting (AAA) process. This problem is resolved in
Release 12.1(22)E. (CSCec85347)
• Directed broadcasts to a destination network that is part of an MPLS VPN fail.This problem is
resolved in Release 12.1(22)E. (CSCec75499)
• The ip pim register source command is not supported in Release 12.1E. This problem is resolved
in Release 12.1(22)E. (CSCec70483)
• When protocol independent multicast (PIM) dense mode is enabled, an interface in the outgoing
interface list may indicate it is in forwarding mode, but the P flag may be set to the group (S,G) state,
which prevents the interface from forwarding packets. This problem is resolved in
Release 12.1(22)E. (CSCec70428)
• L3-PS-DRVR messages are seen every 12 to 16 seconds. This problem is resolved in
Release 12.1(22)E. (CSCec63833)
• When an interface that is configured with multiple IP multicast helper maps for the same group
address and for different broadcast addresses is removed, it generates false memory-access errors.
If the interface is reconfigured and removed again, the router will crash. This problem is resolved in
Release 12.1(22)E. (CSCec63186)
• With a 13-slot chassis, a bus error and reload might occur if you configure EtherChannels that
include any slot 13 ports. This problem is resolved in Release 12.1(22)E. (CSCec49438)
• Incorrect processing of received PIM packets causes IGMP snooping to fail. When this occurs, the
system is unable to learn the correct outbound interface for the multicast traffic. This problem is
resolved in Release 12.1(22)E. (CSCec46892)
• After you remove a Cisco IOS ACL from an interface, the packets continue to be passed or dropped
as they would with the Cisco IOS ACL still attached. This problem is resolved in Release 12.1(22)E.
(CSCec43666)
• With VLAN aging configured, the routed MAC (RM) bit might be set on the Layer 2 entries for
routed traffic, which causes the entries to be purged every 5 minutes. One packet might be flooded
and relearned for each purged entry. This problem is resolved in Release 12.1(22)E. (CSCec43605)
• A FIB-related memory leak might occur. This problem is resolved in Release 12.1(22)E.
(CSCec43573)
• For BGP routes learned through a WAN interface, if the BGP neighbor goes down, the default route
adjacency does not change if the default route learned through BGP had a better metric than a static
route configured locally. This problem is resolved in Release 12.1(22)E. (CSCec41005)
• An IGMP packet flood might cause a reload. This problem is resolved in Release 12.1(22)E.
(CSCec39132)
• With an MPLS PE configuration, some IP-to-tag adjacencies might be incorrectly installed on the
switch processor after interfaces go up and down and a large number of BGP routes need to be
resolved. This problem is resolved in Release 12.1(22)E. (CSCec30461)
