Configure the Hello timer and
Fail timer for the RRPP domain
timer hello-timer hello-value
fail-timer fail-value
Required
By default, the Hello timer value
is 1 second and the Fail timer
value is 3 seconds.
z The Fail timer value must be equal to or greater than three times the Hello timer value.
z To avoid temporary loops when the primary ring fails in a dual-homed-ring network, ensure
that the difference between the Fail timer value on the master node of the subring and that
on the master node of the primary ring is greater than twice the Hello timer value of the
master node of the subring.
Configuring RRPP Fast Detection
The S7500E series Ethernet switches support RRPP fast detection only after SD or EB cards
are mounted in them.
Enabling Fast Detection
Perform this configuration on the master node, edge node, and assistant-edge node in the
RRPP domain to be configured.
Follow these steps to enable fast detection:
