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.

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.

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.
