Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S2
Conditions: This symptom has been observed on a GSR running Cisco IOS Release 12.0(32)S
060307 nightly image where the GSR is acting as a PE router. The router is configured with unicast
VPN and multicast VPN and unicast and multicast traffic is flowing through the router.
Workaround: There is no workaround.
CSCsd73063
Symptoms: After removing VRF, the following message with tracebacks is observed:
%GENERAL-3-EREVENT, %ALIGN-3-SPURIOUS, and %ALIGN-3-TRACE
Conditions: This symptom has been observed on a Cisco 12000 router with Cisco IOS
Release 12.0(32)S.
Workaround: There is no workaround.
CSCsd75890
Symptoms: On a bulk sync (reload) of a standby route processor (RP) or during an initial router
reload, all MDT configuration is erased on the standby. This erasure causes all MVPN traffic to fail
following an RP switchover.
Conditions: This symptom occurs on a dual RP router in RPR+ or SSO mode with MVPN
configuration. This symptom is only seen in conn_isp and the Cisco IOS Release 12.0(32)S throttle
branch.
Workaround: Deconfigure and reconfigure mdt default and mdt data configuration statements
within the VRF configuration.
Further Problem Description: This symptom occurs as a result of a bug in the initial CSCsd09324
commit.
CSCsd77990
Symptoms: Under some Cisco 12000 router configurations after a line card reload of a 4GE ISE line
card or RPR+ switchover, some interfaces on a 4GE ISE line card can stop receiving traffic.
Conditions: This symptom has been observed on a Cisco 12000 router with Cisco IOS
Release 12.0(32)S.
Workaround: There is no workaround. Using the shutdown and no shutdown commands on the
main interface recovers from this symptom.
CSCsd82249
Symptoms: In MPLS VPN topology, where E3 4xOC12 ATM line card is a Core-facing line card,
after performing a reload on any of Egress line cards, the ATM line card may reload.
Conditions: This symptom has been observed on a E3 4xOC12 ATM line card configured with
MPLS Aware Netflow, on a Cisco 12000 series that runs Cisco IOS Release 12.0(32)S2 or
12.0(32.1)S4.
Workaround: There is no workaround.
CSCsd88944
Symptoms: Decapsulation traffic stops forwarding if traffic for the encapsulation stream is stopped
when MVPN traffic is flowing bi-directionally on a PE router and the two streams collide with each
other and the encapsulation stream occupies the hardware hash table entry.
Conditions: This symptom has been observed when sending MVPN traffic in both directions on an
E3 line card, ensuring that one stream collides with the other stream.
Workaround: Use the clear ip mroute [vrf vrf-name] {* | group [source]} to clear this issue.
