Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8

OL-10394-05 Rev. R0

Switch(config-if)#arp timeout 300

Further Problem Description: While a MAC address is in this condition, the following outputs will

look like this:

Switch#show mac-address-table address 0000.0000.0001 all det

MAC Table shown in details ========================================

PI_E RM RMA Type Alw-Lrn Trap Modified Notify Capture Flood Mac Address Age Pvlan SWbits

Index XTag

----+---+---+----+-------+----+--------+------+-------+------+--------------+----+------+------+------+----

Module 1: No No No DY No No Yes No No No 0000.0000.0001 0x3A 360 0 0x7FFF 0 Active

Supervisor: No No No DY No No Yes No No No 0000.0000.0001 0x69 360 0 0x342 0

Here, we see that the MAC address is not present on Module 2, which it should be. On Module 1,

we see that the index pointed to is 0x7FFF, which represents the internal drop index in the 6500.

Also, we see the "Flood" bit is set to ’No’. In this condition, all frames egressing Module 1 for this

MAC will be dropped. Had "Flood=Yes", the frames would be flooded instead of dropped, which is

normal behavior.

• CSCso42210

Symptoms: Following reload, controllers come up, but interfaces stay down.

Conditions: A router with HA Sup720 and non-HA Sup32 is connected with 8xCHT1/E1 SPA,

1xCHSTM1 SPA and 4xCT3 SPA in a SIP-200. Upon reloading 8xCHT1/E1 SPA alone on both

sides simultaneously, 6-7 interfaces go down and never come up. They show as up/up in line card

but up/down in RP.

Workaround: There is no workaround.

• CSCso84507

Symptoms: When a downgrade is done from Cisco IOS Release 12.2(33)SB to Release 12.2(31)SB,

the Standby that is loaded with Cisco IOS Release 12.2(31)SB fails to do config sync and keeps

crashing.

Conditions: This symptom occurs when both Active and Standby are loaded with Cisco IOS Release

12.2(33)SB image with PPPOX (PPPoA or PPPoE) configurations. Standby is downgraded to Cisco

IOS Release 12.2(31)SB. The standby loaded with Cisco IOS Release 12.2(31)SB fails to do

configuration sync and keeps crashing after configuring issu loadversion command.

This is also seen in the case of an upgrade from Cisco IOS Release 12.2(31)SB* to Cisco IOS

Release 12.2(33)SB image, after issu runversion command, when Active has Cisco IOS Release

12.2(33)SB and Standby has Cisco IOS Release 12.2(31)SB* image.

Workaround: For upgrade from Cisco IOS Release 12.2(31)SB* to Cisco IOS Release 12.2(33)SB

image:

After issu runversion command, when Active has Cisco IOS Release 12.2(33)SB:

1. Configure the following:

router#configure terminal router(config)#redundancy router(config-red)#force-rpr 1

2. Cisco IOS Release 12.2(31)SB* becomes Standby and will crash once and then come up in RPR

mode.

3. Do issu commitversion and Standby will come up with Cisco IOS Release 12.2(33)SB image.

For downgrade from Cisco IOS Release 12.2(33)SB to Cisco IOS Release 12.2(31) SB* image:

1. Configure the following on Active PRE Cisco IOS Release 12.2(33)SB:

router#configure terminal router(config)#redundancy router(config-red)#force-rpr 1

1 2 ... 83 84 85 86 87 88 89 90 91 92 93 ... 397 398
