3. Troubleshooting Functional Failures in Operation

3.13 Communication Failure on High-reliability Function

3.13.1GSRP Communication Failures

If the communication is not possible in the GSRP configuration, isolate the problem according to the failure analysis method shown in the table below.

1

On this system and remote system

Go to No. 2 if one system is master and the other system is non-master.

 

constituting a GSRP group, check the status

 

 

If either system is Backup (No Neighbor), recover from the communication failure

 

of the VLAN group to which the failed

command.

 

monitoring, discarding control, or shaper of the QoS control.

 

 

 

 

See "3.23.1 Checking Filtering/QoS Setting Information" to check for it.

 

 

If necessary, change the system that is Backup (No Neighbor) to Master using the

 

 

set gsrp master command.

 

 

If both systems are Backup or Backup (Waiting), check to see if the master/backup

 

 

selection method (Selection-Pattern) is the same between the systems.

 

 

 

 

 

If both systems are Backup (Lock), reset the lock status of either or both systems.

 

 

 

 

 

If both systems are Master, restart either GSRP program using the restart

 

 

gsrp command.

 

 

In other cases, temporary status transition is in progress. Wait for a while for the

 

 

communication to recover.

 

 

 

2

Check the status of the VLAN port on this

path.

 

 

If the conditions below are all met, activate the VLAN port using the activate

 

 

 

 

command.

 

 

• The MAC address table flash method for the current VLAN port is "Reset"

 

 

(determine by using the show gsrp command with "port" parameter

 

 

specified).

 

 

Go to No. 3 if there is no failure on the VLAN port of this system or systems on

 

 

the communication path.

 

 

 

3

Check the MAC address table flash method

If the MAC address table flash method is either GSRP or Reset and does not match

 

(GSRP/Reset/No) to the VLAN port on this

the configuration, correct it using configuration command gsrp

 

system using the show gsrp command

reset-flash-port and gsrp no-flash-port.

 

with "port" parameter specified.

If the MAC address table flash method is either GSRP or Reset and matches the

 

 

 

 

configuration, restart the GSRP program on this system with the restart gsrp

 

 

command.

 

 

If the MAC address table flash method is No, wait for aging of MAC address table

 

 

on the neighboring system on the communication path.

 

 

 

If master/backup is not switched as expected in the GSRP configuration, isolate the problem using the failure analysis method shown in the table below.
