Description (partial)


If a Stateful Switchover (SSO) is done with a local switching connection
between an Ethernet interface and a VLAN with the VLAN's physical interface
shut down, followed by doing <CmdBold>no shutdown<noCmdBold> on the
physical interface, the connection never comes up and packets fail to
traverse the connection.


This symptom has been observed in IOS-XE Release 3.12 and later on the
ASR1000 platform.
