Caveats
• Systems running a Release prior to 12.1(13)E1 might display the following message and reload:
%ALIGN-1-FATAL: Illegal access to a low address" 02:58:35:
%IPC-SP-5-INVALID: Seat in Update Last Ack Sequence=0x6F4F-Traceback=
401DE764 401DF8D8 4018BF0C 40189B28 40189D60 40116DD4 05:40:15:
%IPC-SP-5-INVALID: Seat in Update Last Ack Sequence=0xCAC9-Traceback=
401DE764 401DF8D8 4018BF0C 40189B28 40189D60 40116DD4
%ALIGN-1-FATAL: Illegal access to a low address addr=0x39,
pc=0x401DE740, ra=0x401DE71C, sp=0x42DC10A8
This problem is resolved in Release 12.1(13)E1. (CSCdy87300)
• When hardware switching is enabled, packets for (S,G) PR bit entry are not installed in hardware
and are not forwarded using the (*,G) entry. This problem is resolved in Release 12.1(13)E1.
(CSCdy73313)
• An incorrect traceback message is generated during boot up or reload of a system running
Release 12.1(13)E. This problem is resolved in Release 12.1(13)E1. (CSCdy79272)
• When you enter the ip igmp snooping and no ip igmp snooping interface commands on a VLAN
interface in a system running Release 12.1(13)E, the configuration is applied globally and the
interface configuration mode changes to global configuration mode. This problem is resolved in
Release 12.1(13)E1. (CSCdy87384)
• The ACL command keyword established does not work with PFC2. This problem is resolved in
Release 12.1(13)E1. (CSCdz00544)
• Port channel configuration may be lost after an RPR+ forced switchover. This problem is resolved
in Release 12.1(13)E1. (CSCdz10789)
Resolved General Caveats in Release 12.1(13)E
• The drop counters on Gigabit Ethernet interfaces might incorrectly increment excessively, even
during low traffic conditions. No data is actually dropped. This problem is resolved in
Release 12.1(13)E. (CSCdv86024)
• There is no Layer 3 hardware-switching support for multicast traffic that needs to be fragmented and
which passes through ingress and egress interfaces that have different MTU sizes. This problem is
resolved in Release 12.1(13)E. (CSCdx95080)
• If a (S,G) state is created by receiving a prune at the source’s first hop router, and then if the source
starts sending, the registering process does not occur, which leads to the loss of multicast traffic.
This usually happens when the source was sending traffic initially, and then stopped sending, and
then starts sending again. This problem is resolved in Release 12.1(13)E. (CSCdw71336)
• A reload might occur when you enter the show ip mroute command. This problem is resolved in
Release 12.1(13)E. (CSCdx79227)
• Following a reload command, the redundant supervisor engine might not boot properly. This
problem is resolved in Release 12.1(13)E. (CSCdw39543)
• With a Supervisor Engine 1, some traffic that does not match the routing policy is policy routed.
This problem is resolved in Release 12.1(13)E. (CSCdx17428)
• A reload might occur while displaying the group-rp mapping cache. This problem is resolved in
Release 12.1(13)E. (CSCdw16433)
• The IGMP ROBUSTNESS_VAR is increased from 1 to 2 in Release 12.1(13)E. (CSCdt45806)
• With Cisco IOS SLB configured, a reload might occur following these messages: “Unexpected
exception, CPU signal 10, PC = 0x602D8934” or “%ALIGN-1-FATAL.” This problem is resolved
in Release 12.1(13)E. (CSCdy40171)
