Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCte14504
Symptoms: Router crash with TLB (load or instruction fetch) exception.
Conditions: The symptom is observed with a reload of the router that is running a Cisco IOS
SRD Release.
Workaround: There is no workaround.
Further Problem Description: This is memory issue and so it might not be seen at every reload. In
the local testbed, the crash is seen after a reload with a few VRF configurations under VLAN.

Symptoms: A Cisco router may reload when an L2TP xconnect pseudowire is configured using a
pseudowire class that has not yet been defined.
Conditions: This symptom is observed when the following sequence of commands is entered:
configure terminal
interface Ethernet0/0.1
encapsulation dot1Q 400
xconnect 10.0.0.1 555 encapsulation l2tpv3 pw-class test
pseudowire-class test
encapsulation l2tpv3
protocol l2tpv3 test
ip local interface Loopback0
vpdn enable
This symptom affects all platforms.
Workaround: Define the pseudowire class using the pseudowire- class configuration command
before referencing that pseudowire class in an xconnect configuration.
CSCte28933
Symptoms: L2TPv3 VLAN-mode reassembled packets get dropped on ES+.
Conditions: The symptom is observed when “L2TPv3 cookie” is configured and L2TPv3 packets
get fragmented in the core or at source.
Workaround: Configure L2TPv3 without cookies.
CSCte37192
Symptoms: Traffic is dropped in the egress by SIP400.
Conditions: The symptom is observed when BRE is configured, then removed, then reconfigured.
Then perform a shut/no shut on the interface where the PVC is present.
Workaround 1: Perform a shut/no shut on the interface.
Workaround 2: Perform a SPA OIR.
CSCte38652
Symptoms: The standby reloads due to one of the line cards getting powered down with the reason
given as: “Failed to configure the line card”.

amount of configuration.
Workaround: There is no workaround.
