Check the link status by navigating to
Configuration > ERPS.
Select the ERPS
number and verifty that the Protection State displays Idle (meaning the link
is up and working as expected).
Select and then
click .
This ensures the ERPS page automatically refreshes after
the WTR (Wait to Restore) timer ends later in this process.
Disconnect the cable from switch 1 to switch 3 so the link goes down.
Return to the web browser and verify that the Protection
State now displays Protected.
Restore the normal link for switch 1 and switch
3.
Verify the Protection State displays
Pending until the WTR (Wait to Restore) timer
expires.
When the page
refreshes, the Protection
State should return to Idle. If it does not,
see Getting Help to
submit a support ticket, as something else is causing ERPS to fail.
and then
click
