Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsz30839
Symptoms: Switch virtual interface (SVI)-to-SVI Layer 3 ping is failing.
Conditions: Occurs when SVI (VLAN) is configured with IP address on both ends.
Workaround: There is no workaround.
CSCsz37530
Symptoms: Port is shut down, and following error message is displayed:
%SYS-DFC3-2-LINKED: Bad enqueue of 191C92B4 in queue FD9EAD0 -Process= "SCP Hybrid
process"
Conditions: Problem is seen with Cisco 7600 running Cisco IOS Release 12.2SRD image with
Port-channel configured and the member-link used is a ES+ Linecard interface.
Workaround: There is no workaround.
CSCsz39086
Symptoms: With a subinterface or software Ethernet Over MPLS (EoMPLS) configured for a single
tag, QinQ traffic with outer VLAN tag matching the configuration, but with full-range of inner tag
is dropped.
Conditions: All QinQ traffic with the outer tag matching the configured tag on subinterface is
dropped.
Workaround: Use scalable EoMPLS, which provides a versatile range of VLAN matching and has
the required properties as expressed in this defect.
CSCsz40772
Symptoms: Traffic is lost for local forwarding between two EVCs in a VRF.
Conditions: Occurs when VRF includes attachment circuits which are defined as EVCs. Each EVC
is configured on separate bridge-domain and separate IP subnet. Forwarding between remote PEs
works properly but local traffic between the EVCs breaks.
Workaround: Keep the EVC on different NPs on the ES40 or replace EVC and bridge domain
configuration by sub-interfaces.
CSCsz42143
Symptoms: 6148A-GE-TX module resets due to keep-alive failures.
Conditions: Excessive errors and micro link flaps on a port.
Workaround: There is no workaround.
Further Problem Description: This is a rare problem triggered by misbehavior of a 10Base-T hub
when a FastEthernet host is connected to it.
CSCsz43691
Symptoms: If TAL subscribers attempt to logon when the Cisco ASR 1000 series router RADIUS
service download requests a time-out, some sessions will get stuck in "Attempting" state during
user/service authorizations. Once 200 sessions are stuck in this state, no subscriber will be able to
login until all the sessions (those that are active and those that are stuck in "Attempting" state) are
manually cleared using the clear subscriber session all command.
Conditions: The symptom is observed when TAL subscribers attempt to logon while the Cisco ASR
1000 series router RADIUS service download requests a time-out.
Workaround: Use the clear subscriber session all command to manually clear all sessions. This
may be, however, service disruptive and impractical in a production network.
