scenarios.
Condition: This symptom is observed when the E3 ATM is in the CE side.
Workaround: There is no workaround.
• CSCsl68227
Symptoms: An E3 linecard may drop packets larger than a certain size because of a buffer carving
problem when the mtu command is used for multilink interfaces.
Conditions: This symptom is observed with images based on Cisco IOS Release 12.0(32)S10.
Workaround: Changing the MTU or reloading the linecard may clear the problem.
• CSCsl89425
Symptoms: Bidirectional Forwarding Detection (BFD) sessions do not scale. This symptom is
especially visible with an OSPF client when one of the peers is rebooted after configuring the
maximum number of BFD sessions.
Conditions: This symptom occurs when configuring maximum BFD sessions or total number of
BFD sessions too close to the maximum limit.
Workaround: Configure 90 percent of the maximum allowed BFD sessions.
