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.
