Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: There is no workaround.
• CSCsm86832
Symptoms: The line protocol of the serial interface keeps flapping.
Conditions: This symptom is observed after BERT is run simultaneously on more than one fractional
T1 with a Frame Relay sub-interfaces.
Workaround: Add and then remove the T1.
• CSCso29361
Symptoms: The commands given in the interface range command may not be synced to all
interfaces configured in the range in the standby supervisor.
Conditions: Occurs when configuration commands are entered under interface vlan range
command. They get attached to only the first VLAN in the range in the redundant supervisor. After
switchover, traffic does not flow due to the missing VLAN configuration.
Workaround: There is no workaround.
• CSCso40612
Symptoms: Router is crashing due to random memory corruption in parser code.
Conditions: The crash happens on only particular sequence and timing of configuration.
Workaround: There is no workaround.
• CSCso56038
Symptoms: The following error message may be seen:
%DUAL-3-INTERNAL: eigrp 4: Internal Error
Conditions: This symptom is seen when a PE-CE setup using site-of-origin (SoO) tags, in which an
PE router that is running EIGRP can learn the same route both by EIGRP (from a CE neighbor) and
also by redistribution.
The above error may be seen when EIGRP on the PE prepares to send information to a neighbor
about a route learned from another neighbor (with no SoO tag), but before the information can be
sent, the route is replaced by a redistributed route (with an SoO tag). The above error can be seen.
This behavior is very dependent on the timing of this series of events.
Workaround: There is no workaround.
Further Problem Description: It is not clear what functional impact this may have, or whether the
error message is purely a warning.
• CSCso57020
Symptoms: Etherchannel states for Link Aggregate Control Protocol (LACP) port-channels are
inconsistent between active and standby, which could possibly affect traffic forwarding.
Conditions: Occurs while configuring several LACP port channels. This could be seen if LACP port
channels are configured and the device is brought up in SSO mode.
Workaround: Once the standby is completely up in HOT state, perform a shut/no shut on the
interfaces that are inconsistent.
• CSCso74922
Symptoms: Resilient Ethernet Protocol (REP) state flaps after line card reset
Conditions: Occurs on routers running Cisco IOS Release 12.2(33)SRD with SIP600 ports
configured as REP edge ports.
Workaround: There is no workaround.
