Clearing VSRP information

NOTE
All trunk ports must have the same delayed-link-down-event configuration.
The following command will delay the sending of port "down" event for 100ms when a port state is
detected "down". If the port state is detected "up" afterwards within 100ms, the delayed "down"
event is cancelled; otherwise, the "down" event is sent after 100ms. This allows the upper layer
applications not to be affected by a port state flapping.
BigIron RX (config-if-e1000-1/2)# delay-link-event 2 down
Syntax: delay-link-event <time> up | down
The <time> parameter is the number of 50-ms units. The default is 0.
The <up> parameter means only "up" events are delayed.
The <down> parameter means that only the down events are delayed.
Clearing VSRP information
You can clear all VSRP statistics, globally and per-instance, by entering the following command.
BigIron RX# clear vsrp
Syntax: clear vsrp

VSRP and MRP signaling

A device may connect to an MRP ring through VSRP to provide a redundant path between the
device and the MRP ring. VSRP and MRP signaling, ensures rapid failover by flushing MAC
addresses appropriately. The host on the MRP ring learns the MAC addresses of all devices on the
MRP ring and VSRP link. From these MAC addresses, the host creates a MAC database (table),
which is used to establish a data path from the host to a VSRP-linked device.
shows two possible data paths from the host to Device 1.
