Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
hh:mm:ss Date: Address Error (load or instruction fetch) exception, CPU signal 10, PC
= 0x424ECCE4
Conditions: This symptom is observed while using IP SLA.
Workaround: There is no workaround.
CSCtb90653
Symptoms: TCP ports 4509, 4510, and 2222 are opened without any configuration.
Conditions: The following releases are affected: Cisco IOS Release 12.2(33)SRD, 12.2(33)SRD1,
12.2(33)SRD2, 12.2(33)SRD2a, and 12.2(33)ZZ.
Workaround: Disable the listening of the ports with the privileged CLI command: test platform
ezdriver deactivate.
CSCtb99472
Symptoms: Doing an OIR of a PA-2CT3 Port Adapter in subrate mode causes some of the interface
configurations to get lost and the subrate channels to go down.
Conditions: The symptom is observed with Cisco 7200 series routers that is running with Cisco IOS
Release 12.2(33)SRD2.
Workaround: To reapply the serial configuration, perform a “shut/no shut”.
CSCtc01196
Symptoms: ISIS topology is broken after two or three consecutive SSOs with “isis nsf ietf” enabled.
This causes routes to be missing in the routing table and permanent traffic loss.
Conditions: The symptom is observed when “isis nsf ietf” is enabled and the restarting router comes
up too slowly, causing neighboring routers on LAN interfaces to time out.
Workaround: Perform a shut/no shut on the interface and ISIS will re-establish adjacency with the
neighbors on the LAN interface.
CSCtc04459
Symptoms: High CPU is observed when sequential IMSI values are sent in a PDP request and, as a
result, low NDR is observed.
Conditions: The symptom is observed under the following conditions:
1. GTP-SLB is configured.
2. Sequential IMSI values are sent in a GTP PDP request.
Workaround: Use random IMSI values.
CSCtc15394
Symptoms: The parity errors are seen on a 4XOC3-ATM 1XOC3-ATM 1XOC12-ATM SPA while it
is operational and plugged into SIP200 or SIP400 chassis with or without traffic running.
Conditions: No known conditions. Soft errors can happen any time due to environmental effects.
Workaround: There is no workaround.
CSCtc17058
Symptoms: VC stops sending traffic due to duplicate VPN ID in port-based EoMPLS.
Conditions: The symptom is observed on a Cisco 7600 series router that is running Cisco IOS
Release 12.2(33)SRD.
Workaround: Do a shut/no shut on the interface (either on the same interface on which the VC has
stopped sending traffic or an interface which has the port-based EoMPLS configured on the router).
