Cross-Platform Release Notes for Cisco IOS Release 12.0S

OL-1617-14 Rev. Q0

Resolved Caveats—Cisco IOS Release 12.0(27)S2

Workaround: There is no workaround. The fix for this DDTS adds the new show monitor

event-trace psar command to show any bursty error events that are traced but not visible in the

output of the show logging command.

• CSCed15913

Symptoms: An Engine 0 12xE3 line card may reload when changing the MTU on an Engine 2

3x1GE line card.

Conditions: This symptom is observed on a Cisco 12416 router that is running the gsr-p-mz image

of Cisco IOS Release 12.0(26)S.

Workaround: Ensure there is no traffic going through the Engine 0 12xE3 and Engine 2 3x1Ge line

cards when attempting to change the MTU.

• CSCed21111

Symptoms: There is no console response from the primary or secondary route processor.

Conditions: This symptom occurs after the redundancy force-failover main-cpu EXEC command

is sent for the second cutover.

Workaround: There is no workaround.

• CSCed22358

Symptoms: A Cisco 12000 series may forward packets to an incorrect interface. This behavior can

been seen by looking at the hardware CEF entry on this input line card:

execute-on slot x show ip hardware-cef a.b.c.d (a.b.c.d is the destination IP address)

The output looks similar to the following, in which the CEF lookup is null:

LC-Slot0#show ip hardware-cef a.b.c.d Leaf FCR 2 0x784C6FC0 found 2 deep alpha ip

loadbalance: 0x78198D00 - lbl not equal. cef lookup NULL

After clearing the route, the output looks as follows:

LC-Slot0#show ip hardware-cef a.b.c.d Leaf FCR 4 0x784C6FC0 found 2 deep Fast

Adjacency: alpha adjacency: 0x701E8280 [0-7] oi 0x4019100 oq 4000 in 15 ab 0 hl 20 gp

11 tl 0 loq BC01 15/0 mtu 4470 packets 1750013440 bytes 776867999767

Output Queue / Local Output Queue Bundle: [0-7] output queue 0x4000 local output queue

0xBC01

This problem may cause packets to be dropped because a loop is created and the TTL expires for

the packets.

Conditions: This symptom is observed under very specific conditions on a Cisco 12000 series that

runs Cisco IOS Release 12.0(24)S or a later release when traffic that enters an Engine 3 line card

toggles between a static-to-null route and a more specific route as the destination.

Workaround: Avoid the specific conditions mentioned above. Clearing the route resolves the

problem only temporarily.

• CSCed28604

Symptoms: Enabling autonegotiation on an E1 Gigabit Ethernet interface causes the standby route

processor (RP) to fail.

Conditions: This symptom is observed on a Cisco 12000 series router that is running Cisco IOS

Release 12.0(26)S.

Workaround: Stop the traffic, enter the shutdown command on the interface, configure

autonegotiation on the interface, enter the no shutdown command on the interface, and resume the

traffic.
