(M320 routers with Channelized OC3/STM1 Circuit Emulation PIC with SFP only and EX
Series switches) Reduce the Automatic Protection Switching (APS) switchover time in
Layer 2 circuits.
NOTE:
Configuring this statement reduces the APS switchover time only when
the Layer 2 circuit encapsulation type for the interface receiving traffic from
a Layer 2 circuit neighbor is SAToP.
When the fast-aps-switch
you must configure an appropriate value for revert time to achieve reduction
in APS switchover time.
To prevent the logical interfaces in the data path from being shut down,
configure appropriate hold-time values on all the interfaces in the data
path that support TDM.
The fast-aps-switch
option is configured.
The interfaces that have the
be used in virtual private LAN service (VPLS) environments.
