Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
Conditions: This symptom is observed on a 4-port OC-12 ATM line card that is configured for
L2TPv3 and that is installed in a Cisco 12000 series that runs the gsr-p-mz image of Cisco IOS
Release 12.0 S.
Workaround: Reload the line card.
• CSCee42281
Symptoms: Some interfaces on a channelized SONET line card may not carry bidirectional traffic
following an APS switchover. Interfaces may be up and routes may be present when this occurs.
Conditions: The symptom is observed on Cisco 12000 series Engine 3 channelized line cards
(OC-48 or 4XOC-12 channelized to DS-3) that functions in an 1+1 APS configuration. However the
symptom could occur on any channelized APS interface.
Workaround: Enter the shutdown command followed by the no shutdown command on the affected
interfaces.
• 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.
• 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.
• CSCee49862
Symptoms: A Cisco 7500 series multichannel T3 port adapter (PA-MC-2T3+) may not provide a
two-second delay before bringing down the T3 controller.
Conditions: This symptom is observed when an alarm as defined in the ANSI T1.231 specification
occurs.
Workaround: There is no workaround.
• CSCee49983
Symptoms: When the controller of multichannel T3 port adaptor (PA-MC-2T3+) goes down for a
short duration and an alarm occurs, the port adapter does not report the type of alarm.
Conditions: This symptom is observed on a Cisco 7200 series and Cisco 7500 series that are
configured with a PA-MC-2T3+. The port adapter should provide a history table of recent alarm
conditions along with a corresponding time stamp to allow for proper troubleshooting.
