Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S3
CSCsu36958
Symptoms: A router cannot be reloaded after the RP switches over three times.
Conditions: The router restarts three times, and each time due to watchdog timeout due to failure to
allocate memory. This symptom is related to a flood of multicast messages. Once this symptom
occurs, attempts to manually reload the router are unsuccessful as the NVRAM is locked, indicating
that it is being updated.
Workaround: There really is no workaround except to manually remove and re-insert the RP or
power-cycle the chassis.
CSCsu40491
Symptoms: When a second multilink is enabled between a PE and a connected CPE, the route may
not be propagated to the remote PE. A ping from the local PE to the CPE always works fine over
both multilinks; however, a ping from the remote PE to the CPE does not work when both links are
enabled.
Conditions: This symptom is observed under the following conditions:
1. The routing protocol between the PE and the CE is BGP.
2. Two static routes are defined on the PE toward the CE.
3. MLPPP is used on both links.
4. The PE is a Cisco 12000 series Internet router.
5. Both links are enabled.
These conditions do not guarantee that the problem will be reproduced; but it may occur under
certain circumstances.
Workaround: Perform either of the following two workarounds:
1. To clear the issue, redefine the static routes, or shut down both multilinks and bring them back up
again.
2. Enable only one multilink.
Further Problem Description: The MPLS label shows as “aggregate” instead of “untagged” during
the problem.
CSCsu41338
Symptoms: Set cos is not being applied for VPLS packets in E5 Gig. The source MAC address of
the VPLS packet from the disposition PE is getting corrupted.
Conditions: This symptom is observed only for VPLS packets in E5 cards when a service policy with
set cos is applied to the egress interface of the disposition PE.
Workaround: There is no workaround.
CSCsu54160
Symptoms: An RP becomes stuck.
Conditions: This symptom is observed after an SSO mode redundancy force switchover is executed.
Workaround: Reload the secondary RP.
CSCsu59282
Symptoms: The following message is continuously seen on SSO switchover even if the maximum
scale numbers are not configured.
%RP-3-ENCAP: Failure to allocate encap table entry, exceeded max number of entries,
slot 3 (info 0xC0000
