Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• Changes in the Unicast routing table can cause an inconsistency between software and hardware
programming of the RPF interfaces of specific multicast groups. This inconsistency causes
group-specific multicast traffic to be lost. This problem is resolved in Release 12.1(8b)E14.
(CSCdz44110)
• 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(8b)E14. (CSCdz16276)
• With multicast support configured, a reload might occur when an interface flaps. This problem is
resolved in Release 12.1(8b)E14. (CSCdy89663)
• 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(8b)E14.
(CSCdy73313)
• 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(8b)E14. (CSCdy72767)
• 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(8b)E14. (CSCdy60995)
• In rare situations, an MSFC2 might freeze when it can receive control traffic from the supervisor
engine, but it cannot send it. This problem is resolved in Release 12.1(8b)E14. (CSCdy15598)
• A reload might occur when you enter the no ip routing command. This problem is resolved in
Release 12.1(8b)E14. (CSCdy02831)
• A reload might occur when you enter the show ip mroute command. This problem is resolved in
Release 12.1(8b)E14. (CSCdx79227)
• A multilink PPP bundle might forward traffic intermittently. This problem is resolved in
Release 12.1(8b)E14. (CSCdx48611)
• To avoid a reload, do not shut down any interfaces while another user is displaying the output from
the show ip pim neighbor command. This problem is resolved in Release 12.1(8b)E14.
(CSCdx25551)
• A reload might occur following a “%ALIGN-1-FATAL” message. This problem is resolved in
Release 12.1(8b)E14. (CSCdx22902)
• A Gigabit Ethernet EtherChannel formed with DFC-supported ports and nonDFC-supported ports
and configured not to use PAgP may stop passing traffic if you reset or OIR one of the Gigabit
Ethernet switching modules. This problem is resolved in Release 12.1(8b)E14. (CSCdx00390)
• When an (S,G) entry with the T flag set transitions to an (S,G,R) entry an (S,G) RP-bit prune is sent
towards the source instead of towards the RP. This problem is resolved in Release 12.1(8b)E14.
(CSCdw95442)
• A multicast output interface might be added to the output interface list more than once. This problem
is resolved in Release 12.1(8b)E14. (CSCdw54615)
• Following a reload command, the redundant supervisor engine might not boot properly. This
problem is resolved in Release 12.1(8b)E14. (CSCdw39543)
• A reload might occur when you enter the show ip mroute command. This problem is resolved in
Release 12.1(8b)E14. (CSCdw20251)
