CSCts95896
Symptoms: The router stops passing traffic on EVC interfaces.
Conditions: Occurs when you issue the default interface command and immediately restore the
configuration. The issue occurs with configurations containing either a large number of EFPs or
features that impact EFP programming at a lesser scale, such as QoS.
Workaround: Wait for the router to clear the old EFP configuration before adding a new
configuration.
CSCty30951
Symptom: The router displays the following console error message:
%QOSMGR-3-OUT_OF_TCAM_RESOURCES: SIP0: nile_mgr: Out of tcam resources to execute
command
Conditions: Occurs when you remove a QoS configuration by setting the interface to the default
configuration.
Workaround: There is no workaround.
CSCty34054
Symptom: The router displays CPU utilization traceback messages and drops all multicast traffic
for 2050 seconds.
Conditions: Occurs under the following conditions:
Multicast is enabled with more than 500 multicast groups.
–
The router is using RSP1B in SSM mode.
–
BDI is configured on the access side of the router.
–
There are 24 EFPs on each bridge domain.
–
You enter a shutdown command on the access interface.
–
Workaround: There is no workaround.
CSCty76744
Symptom: The show mac-address-table command does not show all of the EFPs with a given static
MAC address; the command only displays the first EFP with the MAC address.
Conditions: Occurs when you configure the same static MAC address on multiple EFPs.
Workaround: There is no workaround; however, the issue is cosmetic and functionality is not
affected.
CSCua22323
Symptom: Bit error rate testing (BERT) does not go in sync state.
Conditions: Occurs when you configure BERT on the PDH controller in local loopback mode.
Workaround: Initiate BERT on both ends of the connection.
CSCua25779
Symptom: An Ethernet virtual circuit (EVC) interface does not forward IPv4 traffic.
