Caveats for Cisco IOS Release 12.0
78-6455-12
Miscellaneous
None of the point-to-point adjacencies show up in the VIP for the serial port when the show
adjacency detail EXEC command is used in the VIP slot console. Valid adjacencies are present in
the RP and are displayed when the show adjacency detail command is issued on the main console.
Workaround: Enable only the ip cef global configuration command when you bring up the router.
Then turn on the ip cef distributed command if needed. Pings are functional when just the ip cef
command is configured.
Alternate workaround: After the router reloads, toggle the ip cef distributed configuration by
entering the no ip cef distributed command, followed by the ip cef distributed command.

Removing and then adding a channel group from the configuration of a PA-2CE1 port adapter may
cause the output to stick followed by a cbus complex; thereby producing the following error
message:
%RSP-3-RESTART: interface Serial4/0/1:11, output frozen
%RSP-3-RESTART: interface Serial4/0/1:12, output stuck
%RSP-3-RESTART: cbus complex
There is no workaround.
• CSCds23223
A configuration involving an ingress professional services automation (PSA) access list(ACL) on
one line card, combined with an output ACL and output committed access rate (CAR) on another
line card, could result in a line card reload when traffic is passed through this path. There is no
workaround.
• CSCds25711
A Cisco 3640 router with 1- or 2-port network module NM-1E2W= may experience output queue
wedged under load. There is no workaround.
• CSCds25745
A Cisco 4700 series router with ATM and Ethernet interfaces reloads periodically while running
Cisco IOS Release 12.0(12). There is no workaround.
• CSCds33876
When using IP Security (IPSec), a Cisco 2514 router running Cisco IOS Release12.0(12) may
reload unexpectedly with a software forced reload. Decoded tracebacks are consistent with memory
corruption. There is no work around.
• CSCds34988
It is possible on a Cisco gigabit switch router (GSR), that the 6 Port CT3 card experiences problems
with the fabric weighted random early detection/Modified deficit round robin (WRED/MDRR)
when there is congestion at the Egress of this Line Card. This is seen by applying WRED/MDRR
on the fabric direction, however there will be no noticeable impact. This was experienced when
running special image: gsr-p-mz.120-12.6.S2. There is no workaround.
• CSCds38804
Some Sandisk 48 MB flash cards do not boot. There is no workaround.
• CSCds40078
When Routing Information Protocol (RIP) is running on an interface, and the IP address is
deconfigured, RIP stops running on the correct interface. After this situation occurs, if a new IP
address is configured that falls under the RIP network statements, RIP will not start running on the
interface again.
Workaround: Deconfigure RIP, and reconfigure it again.
