Resolved Caveats—Cisco IOS Release 12.0(28)S1
Workaround: Reload the line card.
CSCee43259
Symptoms: In the case of a Cisco 12000 series router using Supervisor Engine 3 ISE QOC12 ATM
card, Route Processor (RP) may hang for about 15-20 minutes when the following two steps are
done:
Conditions:
Configure 1K ATM PVCs (1K ATM sub-interfaces) with a class-default (queue-limit) based
service-policy configured on all of the PVCs (service-policy should be configured under each
PVC to see RP hangs and crash).
On removing the above 1k ATM PVCs (sub-interfaces), RP hangs for about 15-20 minutes
before the user can regain control.
The following warning message may show up when deleting the ATM sub-intfs:
%WARNING: Features on ATM6/0.1 haven't been removed Please wait for approximately
ten minutes and retry.
% Removal of physical interfaces is not permitted.
On adding the 1K sub-intfs again (2nd attempt), RP crashes. This RP crash is reproducible.
Workaround: There is no workaround.
CSCee43562
Symptoms: The feature manager queue on the Route Processor may not drain for 20 minutes after a
reload in a scaled environment with 1400 IP and L3VPN connections (subinterfaces). The feature
manager pushes ACL and PBR configurations to the IP Services Engine (ISE) line cards for TCAM
processing. You can monitor the state of the feature manager queue with the show fm queue
command.
Conditions: This symptom is observed on a 12000 series that runs Cisco IOS Release 12.0(28)S and
may occur on any ISE line card that uses an associate message in the QoS manager.
Workaround: There is no workaround.
CSCee43569
Symptoms: The TE DB on a tunnel headend may become corrupted.
Conditions: This symptom is observed on a Cisco router that has MPLS configured.
Workaround: There is no workaround.
CSCee43880
Symptoms: After reloading an E2 16-port OC-3 POS line card that is a member line card of POS
channel, the peer POS channel members do not become active members again.
Conditions: The symptom is observed on a link-bundling interface of a Cisco 12000 series router
that runs Cisco IOS Release 12.0 S.
Workaround: There is no workaround.
CSCee45099
Symptoms: A Cisco 12000 series 8-port OC-48 or 2-port OC-192 line card may crash.
Conditions: This symptom is observed when the line card is configured for MPLS-TE FRR.
Workaround: There is no workaround.
CSCee47026
Symptoms: The ATM HA process may crash.
