www.qtech.ru

 Usage Guide: If domain ID of ERRP needs to be configured, the compatible mode of

ERRP should be enabled firstly. When executing this command, it should create a new

ERRP domain if there is no ERRP domain. However, the no command is used to delete

the corresponding domain ID of ERRP.

 Example: Configure domain ID for ERRP globally.

 Switch(Config)#errp domain 1

3.6 fail-timer

 Command: fail-timer <timer>

o 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.

 Example: Configure fail timer of MRPP ring 4000 to 10s.

 Switch(config)# mrpp ring 4000

 Switch(mrpp-ring-4000)#fail-timer 10

3.7 hello-timer

 Command: hello-timer <timer>

o 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: <timer> 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.

 Switch(config)# mrpp ring 4000

 Switch(mrpp-ring-4000)#hello-timer 3
