CSCuf79504
Symptom: ATM Virtual Channel Connections (VCCs) creation on standby RSP fails.
Conditions: This issue occurs after issuing shutdown command followed by no shutdown
command on the multiple controller on active RSP.
Workaround: There is no workaround.
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.
CSCtz65778
Symptom: The control plane goes down with VPNv6 traffic.
Conditions: Occurs with 64-byte VPNv6 traffic. The issue only occurs for small, tunnelled packets.
Workaround: There is no workaround.
CSCua57325
Symptom: The router displays an OIR SPA error.
Conditions: Occurs under the following conditions:
The router is running offloaded CFM sessions over an xconnect (pseudowire) interface.
–
The router is using a redundant hardware (dual RSP) configuration.
–
The remote router is using a non-redundant (single RSP) hardware configuration.
–
You reload the router.
–
Workaround: There is no workaround.
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.
CSCub18160
Symptom: The router drops traffic on a link twice and displays a remote fault error message.
Conditions: Occurs when you issue an interface module reset (OIR) while the 10.000M XFP
(DWDM Edge performance) or XFP10GER-192IR-L XFPs are plugged into the ten Gigabit
Ethernet interface module and active.
Reloading the router also takes significantly longer when using these XFPs.
