4 Execute the show axrp command to
check the ring port for each VLAN
group and its operation state.
Go to No. 5 if "Ring Port" and "Role/State" correspond to the port state of network
configuration.
Otherwise, check the configuration.
5 Execute the show axrp detail
command to check the control VLAN
ID.
Go to No. 6 if "Control VLAN ID" corresponds to the VLAN ID of network
configuration.
Otherwise, check the configuration.
6 Execute the show axrp detail
command to check the VLAN ID which
belongs to the VLAN group.
Go to No. 7 if "VLAN ID" corresponds to the VLAN ID of network configuration.
Otherwise, check the configuration.
7 Execute the show axrp detail
command to check timer values for
transmission interval and hold time of
the health check frame.
Go to No. 8 if the timer value "Health Check Hold Time" of the health check frame
hold time is larger than the timer value "Health Check Interval" of the health check
frame transmission interval (i.e. transmission delay is considered).
Check and review the configuration if the timer value of the health check frame hold
time is equivalent or smaller than the that of health check frame transmission interval
(i.e. transmission delay is not considered).
8 Execute the show vlan detail
command to check the VLAN which is
used in Ring Protocol and its port state.
Go to No. 9 and 10 if there is no failure on the VLAN and its port state.
Check the configuration and restore the state if there is any failure.
9 Check settings of the filtering and QoS
control.
Ring Protocol control frames may have been discarded by filtering or QoS control.
See "3.23.1 Checking Filtering/QoS Setting Information" to check the setting. Also
see the manual "Configuration Guide."
10 Check the settings of the virtual link if
spanning tree or GSRP is used at the
same time.
Check to see if virtual link has been correctly configured for the network
configurations.
• Check to see if the virtual link settings of devices that Ring Protocol and either one
of spanning tree or GSRP are used together are correct.
• As for equipment in the whole ring network, confirm the VLAN used as a virtual
link belongs to the VLAN group of Ring Protocol.
