Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S5
Miscellaneous
• CSCeb68673
Symptoms: On an ASBR-PE, the TFIB may be missing a forwarding entry for a prefix that is learnt
from a PE.
Conditions: This symptom is observed on an "ABSR-co-located PE" (that is, an ASBR that also
functions as a PE router) when the PE functionality is removed by deconfiguring VRF, for example,
by entering the no ip vrf vrf-name command.
Since this is a timing issue, it may occur in Cisco IOS Release 12.0 S, Release 12.2 S,
Release 12.2 T, and Release 12.3.
Workaround: There is no workaround.
• CSCeb84128
Symptoms: A Cisco 10000 series may stop responding.
Conditions: This symptom is observed when you attach a child policy map with four policing
statements to a parent policy map with a bandwidth queue and when the parent policy map is already
attached to 100 T1 interfaces.
Workaround: Attach the child policy map to the parent policy map before you attach the parent
policy map to the interfaces.
• CSCec25942
Symptoms: A POS Engine 2 line card originates a high traffic volume to a downstream router over
a POS link because the same packet is sent over and over.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(22)S5.
Workaround: There is no workaround.
• CSCed16284
Symptoms: Packet precedence on rate-limit actions with transmit is incorrectly remaining the same
because the set-prec- transmit action is not working.
Conditions: The interface configuration includes rate limiting with actions that sets precedence to
change on conform and/or exceed with the rate-limit command that includes conform-action
set-prec-transmit 1 and exceed-action set-prec-transmit 0. The packets received are initially at
Precedence of 2, but instead of changing to either a Precedence of 1 or a Precedence of 0, all packets
are transmitted still at a Precedence of 2. The numbers 0, 1, and 2 are examples and can be any
number in the range of 0-7.
Workaround: There is no workaround.
• CSCed89760
Symptoms: When a primary CSC switchover happens on a Cisco 12800 series, a line card may reset.
Conditions: This symptom is observed when there is primary CSC switchover, either through a CLI
command or a physically removal of the primary CSC.
Workaround: There is no workaround.
• CSCee04893
Symptoms: A Cisco router is not able to forward traffic to a TE tunnel.
Conditions: This symptom has been observed on a Cisco 10000 running Cisco IOS
Release 12.0(26)S1 and Release 12.0(27.3)S1 with Multilink PPP + MPLS + TE Tunnel.
