62-3
the MRPP ring is enabled.
Example:
Configure MRPP ring 4000 of switch to primary node, and enable the MRPP ring.
Switch(config)#mrpp enable
Switch(config)#mrpp ring 4000
Switch(mrpp-ring-4000)#control-vlan 4000
Switch(mrpp-ring-4000)# node-mode master
Switch(mrpp-ring-4000)#fail-timer 18
Switch(mrpp-ring-4000)#hello-timer 6
Switch(mrpp-ring-4000)#enable
Switch(mrpp-ring-4000)#exit
Switch(config)#in ethernet 1/0/1
Switch(config-If-Ethernet1/0/1)#mrpp ring 4000 primary-port
Switch(config)#in ethernet 1/0/3
Switch(config-If-Ethernet1/0/3)#mrpp ring 4000 secondary-port
62.5 fail-timer
Command:
fail-timer <timer>
no fail-timer
Function:
Configure if the primary node of MRPP ring receive Timer interval of Hello packet or not, the “no
fail-timer” command restores default timer interval.
Parameter:
<timer> valid range is from 1 to 300s.
Command Mode:
MRPP ring mode
Default:
Default configure timer interval 3s.
Usage Guide:
If primary node of MRPP ring doesn’t receives Hello packet from primary port of primary node on
configured fail timer, the whole loop is fail. Transfer node of MRPP doesn’t need this timer and
configure. To avoid time delay by transfer node forwards Hello packet, the value of fail timer must be
more than or equal to 3 times of Hello timer. On time delay loop, it needs to modify the default and
increase the value to avoid primary node doesn’t receive Hello packet on fail timer due to time
delay.
