Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S8
Conditions: This symptom is observed when traffic flows to an ATM VC that is configured for MLP
with a QoS policy and when the Qos policy has a priority class.
Workaround: There is no workaround.
CSCse32112
Symptoms: On an Engine 3 GE line card, after several switchovers, the show policy-map interface
command output shows MDRR queues unallocated.
Conditions: This symptom is observed on Cisco 12000 series Internet routers with Engine3 GE line
card and with 2 RPs in SSO Mode. An output service policy is applied to the line card. It happens
in a systematic behavior (after the second switchover) if 8Qs/LC have been configured on the line
card. It happens in a random behavior (after a random number of switchover) if 4Qs/LC have been
configured on the line card (default configuration).
Workaround: There is no workaround.
CSCse50262
Symptoms: CE to CE pings fail in an EoMPLS Network when the PE edge facing interface is newly
provisioned in Port Mode (also known as the xconnect command is applied on the interface).
Conditions: This symptom is observed on Cisco IOS Release 12.0(32)SY and EoMPLS is
configured in port mode, on an Engine 3 GiGE line card for a link between PE-CE, and the port is
newly provisioned. This is seen only on one test bed and not seen on other test beds with the same
configurations.
Workaround: The problem goes away by doing a shut command followed by a no shut command
on the newly provisioned interface.
Further Problem Description: Once the workaround is applied, this problem does not happen for that
port even after the router or line card reloads. It also does not affect any traffic or any customers that
are added later on.
CSCsf09508
Symptoms: When passing full 10 Gig Traffic into an E5 LC wherein the Dual priority feature is
enabled and all the 10 Gig traffic is matching the higher priority criteria, the LC crashes. Conditions:
1. Dual priority feature enabled on the E5 LC
2. All the 10 Gig traffic matching the higher priority criteria.
Workaround: Don’t send all 10 Gig traffic as higher priority.

This Unexpected Reload on Cisco 12000 series routers running either GRP or PRP is seen when they
are connected back-to-back and one of them is reloaded or restarted. This problem happens when
BGP IPV4 prefix A recurses over a nexthop PrefixB. Also @a label is configured for the Prefix A.
All works fine in normal condition but when the Nexthop router crashes or when interface
connecting Prefix B flaps, the router crashes.
This problem could happen under following circumstances.
1. we have a recursive BGP route ie BGP aggregate resolved via /32 and vice- versa.
2. BGP IPv4 + label being used
Workaround: 1. Do not use BGP recursive routes.
2. Do not use IPv4 + label in the config
