This problem is resolved in Release 12.1(6)E8. (CSCdw65903)
Resolved Caveats in Release 12.1(6)E1
• When the active supervisor engine shuts down normally, it notifies the redundant supervisor engine
to switch over quicker. Occasionally, this notification fails, resulting in an infinite series of
SYS-2-INTSCHED messages. This problem is resolved in Releases 12.1(5c)E10 and 12.1(6)E1.
(CSCdt21103)
• Occasionally, the active supervisor engine fails to send clock updates to the redundant supervisor
engine, which hangs the heartbeat process on the active supervisor engine. This causes the system
to reload. This problem is resolved in Releases 12.1(5c)E10 and 12.1(6)E1. (CSCdt28184)
• With a large OSPF routing table, the MSFC might experience periods of high CPU utilization and
temporary loss of console communication when redistributing routes. This problem is resolved in
Releases 12.1(5c)E10 and 12.1(6)E1. (CSCdt71785)
Resolved Caveats in Release 12.1(6)E
• No warning message displays if you exceed the maximum number (63) of microflow policers. The
extra policers are displayed by the show mls qos ip command, but they do not work. If classes are
increased beyond the maximum number (255) in a policy map, the policy is rejected without a
warning message if applied to an interface.For Supervisor Engine 2, this problem is resolved in
Release 12.1(8a)E. For Supervisor Engine 1, this problem is resolved in Release 12.1(6)E.
(CSCds38349, CSCdt38130)
• When IGMP snooping receives a GS query, it always replies with a join message. IGMP snooping
should only reply to the GS query if there is at least one nonrouter host port other than the port from
which it received the GS query. This problem is resolved in Release 12.1(6)E. (CSCdt51303)
• The verify command fails when used on a file in the sup-bootflash device. This problem is resolved
in Release 12.1(6)E. (CSCdt09870)
• Occasionally, when IGMP snooping is enabled, some Layer 3-switched multicast groups might stop
forwarding traffic. This problem is resolved in Release 12.1(6)E. (CSCds28792)
• When VTP traps are enabled and a VTP trap is generated because a version 1 VTP device is
detected, communication between the supervisor engine and the MSFC might fail, which causes a
reload. This problem is resolved in Release 12.1(6)E. (CSCdt44708)
• Downloading images to an Intel Value series 200 Flash card in the PCMCIA slot may in rare
situations fail to write a valid image. This problem is resolved in Release 12.1(6)E (see the related
Release 12.0(7)XE1 resolved CSCdm52806 caveat). (CSCdm52806)
• The copy running-config startup-config command does not save the boot system flash command
in the startup configuration file. Enter the write memory command instead. This problem is
resolved in Release 12.1(6)E. (CSCds43994)
• Changes to the boot system flash command in the startup configuration file are not always copied
to the corresponding ROMMON variable. This problem is resolved in Release 12.1(6)E.
