Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsr64777
Symptoms: A router crashes because of a block overrun (overwriting the memory block).
Conditions: This symptom is observed only when NetFlow version 5 is used.
Workaround: NetFlow version 9 could be used for exporting.
CSCsr72674
Symptoms: There is a possibility the RP could encounter a software exception, resulting in a crash.
Conditions: The symptom is observed with MPLS VPN enabled over a tunnel (GRE, for example)
and when the tunnel is configured to be associated with a user-configured VRF.
Workaround: There is no workaround.
CSCsu04049
Symptoms: Following an SSO, pruning recalculations are not done on the new active supervisor and
all the VLANs that are available on the switch are put into a not-pruned list.
Conditions: The symptom is observed following an SSO on the new active supervisor.
Workaround: There is no workaround.
Further Problem Description: The join messages from the peer are not handled because flag clearing
after the VLAN addition is not occurring on the standby. Thus, after the standby becomes active, the
pruning recalculations do not occur.
CSCsu45210
Symptoms: After upgrading from Cisco IOS Release 12.2(18)SXF8 to 12.2(33)SXH2, the standby
supervisor constantly reloads with no error messages.
Conditions: The symptom is observed after a software upgrade using the standby. The standby is
reloaded with the new software, there is a switchover, then the standby is reloaded again.
Workaround: Remove the port security configuration on all ports.
CSCsu46644
Symptoms: After the router reboots, the username/password prompt does not appear after three
minutes. The following message is shown instead of the router login prompt:
% Authentication failed
Conditions: The symptom is observed on a router that is running Cisco IOS interim
Release 12.2(33.1.18)SB1.
Workaround: Add the “no no aaa account system guarantee-first” configuration.
CSCsu59900
Symptoms: Standby RP crashes.
Conditions: Occurs when a shut/no shut is performed on the subinterface with a anything over
MPLS (AToM) VP configured.
Workaround: There is no workaround.
CSCsu76993
Symptoms: EIGRP routes are not tagged with matching distribute-list source of route-map.
Conditions: Problem is observed where the route-map is applied to a specific interface. When the
route-map is applied globally without the specific interface things appear to work fine.
Workaround: There is no workaround.
