21.3.5 fail-timer
Command：fail-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： valid range is from 1 to 3000s.
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.
Example： Configure fail timer of MRPP ring 4000 to 10s.
Switch(Config)# mrpp ring 4000
Switch(mrpp-ring-4000)#fail-timer 10
21.3.6 hello-timer
Command：hello-timer
no hello-timer
Function： Configure timer interval of Hello packet from primary node of MRPP ring, the
“ no hello-timer”command restores timer interval of default.
Parameter： valid range is from 1 to 100s.
Command Mode：
MRPP ring mode
Default： Default configuration timer interval is 1s.
Usage Guide： The primary node of MRPP ring continuously sends Hello packet on
configured Hello timer interval, if secondary port of primary node can receive this packet
in configured period; the whole loop is normal, otherwise fail. Transfer node of MRPP ring
doesn’t need this timer and configure.
Example： Configure hello-timer of MRPP ring 4000 to 3 seconds.
