Immediate revertive switchover: The local PE immediately switches traffic to the master PW
and notifies the fault to the remote PE of the backup PW. The PE notifies the fault recovery
to the remote PE of the backup PW after the period of resume-time.
Delayed revertive switchover: The PE switches traffic to the master PW after the period of
delay-time.
None revertive switchover: The PE does not switch traffic to the master PW until the backup
PW is faulty.
If the remote shutdown function is configured on the interface of a PE that connects to a CE,
do not use the policy of immediate revertive switchover, because this policy may lead to
network flapping and traffic loss. You can use the policy of delayed revertive switchover
and set delay-time equal to or more than 30 seconds.
If the Ethernet OAM function is configured on the interface that connects the PE to a CE,
and the revertive switchover policy is configured, then the value of resume-time cannot be
0. The value must be equal to or more than one second.
Run the display mpls l2vc [ vc-id | interface interface-type interface-number ] command
on the PE to view information about the local end of the PW.
Run the display mpls l2vc brief command on the PE to view brief information about the
local end of the PW.
Run the display mpls l2vc remote-info [ vc-id ] command on the PE to view information
about the remote end of the PW.
Run the display mpls l2vpn forwarding-info [ vc-label ] interface interface-type
interface-number [ | { begin | exclude | include } regular-expression ] command to view
forwarding information about the L2VPN.
