Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: The symptom is observed with the following conditions:
1. Encapsulation QnQ (or dot1q) is configured and removed on the sub-interface, on a WAN
interface (SIP400).
2. Same VLAN configured as Encapsulation QnQ (or dot1q) on a LAN interface (ES+).
3. Perform shut/no shut on the ES+ interface.
Workaround: There is no workaround.

Symptoms: The router crashes when doing concurrent VRF add and deletion configurations.
Conditions: The symptom is observed when a multiple configuration terminal is doing concurrent
VRF add and deletion configurations.
Workaround: Do not do concurrent VRF addition and deletion.

Symptoms: On a Cisco 10000 series router/PRE-3 that is running Cisco IOS Release 12.2(33)SB7
and ISG, the memory on the standby RP may become severely fragmented due to some SSS
functions.
After an SSO switchover, the new-active RP initially takes over with fragmented memory causing
frequent malloc errors and eventually requiring a reload to recover.
Conditions: The symptom is observed on a Cisco 10000 series router/PRE-3 that is running
Cisco IOS Release 12.2(33)SB7 with 10K ISG sessions in a mix of web-login, TAL, prepaid, and
passthrough.
Workaround: A reload will recover memory.
CSCtd35091
Symptoms: The input queue on ISG access interface gets filled up causing the interface to wedge.
Conditions: The symptom is observed when an L2-connected IP session for a client exists on the
ISG and traffic from that client comes in with a different IP address to the one used to identify the
session. This traffic is dropped and interface wedging is observed.
Workaround: There is no workaround other than a router reload.
CSCtd40804
Symptoms: The EVC configuration does not exist on the ES20 line card. The first “show” command
(below) shows that the EVC was known to the Route Processor (RP) on the Supervisor Engine, while
the second command shows that the EVC did not exist on the ES20 line card in slot 4:
#sh ethernet service instance id 3555 interface gi4/0/1
Identifier Interface State CE-Vlans
3555 GigabitEthernet4/0/1 UP
#remote command mod 4 sh ethernet service instan id 3555 int gi4/0/1
EFP ID 3555 on interface GigabitEthernet4/0/1 does not exist
Conditions: The symptom is observed after a Supervisor switchover.
