Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: When FastEthernet SPA on SIP400 is used as the core-facing side, switch virtual
interface (SVI)-based EoMPLS/VPLS traffic does not flow out of the pseudowires. Receiving
Traffic on the pseudowire is fine.
Conditions: Occurs when FE spa on SIP400 is used as the core facing side for SVI-based
EoMPLS/VPLS. All the imposition traffic is dropped.
Workaround: There is no workaround.

Symptoms: Router crashes when we send multiple access packets for same username when
configured for RADIUS Load Balancing (RLB).
Conditions: Occurs with the following topology
CLIENT----->RLB----->SERVER
Client sends multiple access retry packets to server and router crashes after a period of time. This
issue will be seen in cases where multiple access requests are seen for the same username, and 60
seconds expire since the arrival of the first of such access requests, before an accounting start for
the same username is seen.
Workaround: If RLB do not see multiple access packets we wouldn’t see any crash.
• CSCsy87385
Symptoms: For IPv6 adjacencies, MTU is incorrectly programmed.
Conditions: Occurs with simple IPv6/6PE setup.
Workaround: There is no workaround.
• CSCsy92895
Symptoms: When SIP-400 is configured as Lawful Intercept service module, after a line card online
insertion and removal (OIR), the SIP-400 may not get selected as Lawful Intercept service module.
Conditions: Occurs when SIP-400 is configured as Lawful Intercept service module on a Cisco
7600.
Workaround: After line card OIR, select the SIP400 again as the LI service module using the
command li-slot list <sip400 slot number>.
• CSCsy95540
Symptoms: L2TP tunnel not coming up for ATM attachment circuit.
Conditions: The problem is seen on Cisco 7200 router running Cisco IOS Release 12.2(33)SRC.
Workaround: There is no workaround.
• CSCsz08876
Symptoms: Packets are not getting in output policy.
Conditions: Occurs on ES+ card configured for L2TPv3.
Workaround: There is no workaround.
• CSCsz11877
Symptoms: MPLS-TE tunnel label reallocation on midpoint router occurs while RSVP is gracefully
restarting due to CPU switchover.
Conditions: Occurs on a Cisco 7600 that is configured as the midpoint router when the upstream
node is a Cisco IOS-XR router. This does not happen if the upstream node is also a Cisco IOS router.
Because of this label re-allocation, traffic downtime is ~100 msec
