Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S3
• CSCsu73675
Symptoms: In the case of E5 AToM QinQ, set cos is being set on the inner vlan_id.
Conditions: This symptom is observed in an E5 AToM with QinQ configuration that has set cos in
the policy map.
Workaround: There is no workaround.
• CSCsu74140
Symptoms: In E5 L2TPv3 dot1q set cos is not setting on the vlan-id.
Conditions: This symptom is observed in a configuration that has set cos in the policy.
Workaround: There is no workaround.
• CSCsu79988
Symptoms: Before this BGP aspath memory optimization, the memory consumption for aspath has
increased. With this memory optimization, the memory consumption for aspath is reduced.
Workaround: There is no workaround.
• CSCsu84357
Symptoms: The show mac address-table bridge-domain domain command may display
unexpected MAC addresses.
Conditions: This symptom has been reported on a Cisco 12000 series Internet router that is
configured with VPLS. When a service policy with input policing is applied on an interface that also
has bridge-domain configured and when police drops happen, ghost MAC addresses are present in
the MAC address table for that bridge-domain ID.
Workaround: There is no workaround. But no immediate impact on system behavior has been
observed.
Further Problem Description: This issue can occur with either ACL drops or policer drops on a
VPLS-enabled interface. If there are no ACL or CAR drops, this issue will not occur.
This unexpected MAC address might conflict with another real MAC address and may lead to some
other issues such as traffic being sent over the wrong interface for the same customer.
Let us assume that the customer is having two ACs on the same PE and that AC1 learned the proper
MAC address and the unexpected MAC address. If this unexpected MAC address is a valid MAC
address on AC2, then the traffic for this MAC address may be sent to AC1 instead of to AC2.
• CSCsu86288
Symptoms: A line card on a Cisco 12000 series Internet router generates tracebacks during LI
provisioning while installing a 50th tap request. After the appearance of the first traceback, LI
functionality stops working for newly requested taps.
Conditions: This symptom is observed when there are 48 active taps and 2 new taps arrive.
Workaround: Reload the line card or the whole router.
• CSCsu89509
Symptoms: When PEM PS is inserted, there is an increase in CPU utilization by the PowerMgr Main
process. The utilization is from 10 percent to 99 percent; the difference is caused by inserting timing.
Conditions: This issue is observed under the following conditions:
–
16-slot chassis
–
Enhanced fabric
–
Enhanced CSC
