Chapter
Caveats in Cisco IOS XE 3.8S Releases
Workaround: There is no workaround; however, the router applies the QoS policy normally.
• CSCua77688
Symptom: The router experiences remote CFM MEP flapping.
Conditions: Occurs when the router is connected via a CFM xconnect and the link is running a high
traffic rate.
Workaround: Reduce the rate of traffic.
• CSCua90879
Symptom: QoS policies with a police statement on the class-default class do not take effect.
Conditions: Occurs when you apply a police statement to the class-default class within a QoS policy
on an ingress EVC interface.
Workaround: Apply the police statement to a static class, such as class cos0.
• CSCub50477
Symptom: The router does not pass Multicast traffic after a stateful switchover (SSO).
Conditions: Occurs when you issue an SSO while the router is passing Multicast traffic on an
inbound MLP interface.
Workaround: There is no workaround.
• CSCub65096
Symptom: The router crashes when running multicast traffic.
Conditions: Occurs when the router is passing IGMP join messages at a rate of 6 packets per second
over 240 serial interfaces.
Workaround: Send IGMP joins at a lower rate.
• CSCub77354
Symptom: An RSP switchover causes the serial interfaces to flap on the peer device.
Conditions: Occurs when you perform an RSP switchover by physically removing the active RSP.
Workaround: Use the following workarounds:
– Perform an RSP switchover using the redundancy force-switchover command.
– Configure the local device to use clock source line and the remote device to use clock source
internal.
• CSCub78861
Symptom: Following a reload, the router handles CFM only on 128 VLANs or bridge-domains.
Conditions: Occurs when the router configuration contains CFM and more than 128 VLANs or
bridge-domains.
Workaround: There is no workaround.
• CSCuc01154
Symptom: The router does not report B1, B2, and B3 alarms at normal thresholds.
Conditions: Occurs on the OC-3 interface module when the router sends errored frames.
Workaround: There is no workaround.
