No. Items to check and
commands
Action
1Use the
show axrp command to
check the operating status of the
Ring Protocol.
If
enable is displayed for Oper State, go to No. 3.
If a hyphen (
-) is displayed for Oper State, required items for using the
Ring Protocol have not been configured. Check the configuration.
If
disable is displayed for Oper State, the Ring Protocol is disabled.
Check the configuration.
If
Not Operating is displayed for Oper State, the Ring Protocol
functionality is not running. Check the configuration for any conflict (for
example, an incorrect combination of the attribute and ring port for the
operating mode of the Switch). If there is no conflict in the configuration,
for AX6700S, AX6600S, or AX6300S series switches, go to No. 2. For
AX3800S, AX3600S, or AX2400S series switches, go to No. 3.
2Use the
show logging command
to check whether entries are
properly registered in the MAC
address table as the initial
operation of the Ring Protocol.
If the message
The MAC address entry can't be registered at
hardware tables. is not displayed, go to No. 3.
If the message
The MAC address entry can't be registered at
hardware tables. is displayed, the entry setting in the MAC address
table needed to operate the Ring Protocol has failed. See the appropriate
part in the manual Message and Log Reference, and take the action
described in Action. Also, see 4.1.2 Actions to be taken when a MAC
address table resource shortage occurs.
3Use the
show axrp command to
check the operating mode and
attribute.
If the operating mode and attribute defined in the network configuration are
displayed for
Mode and Attribute, go to No. 4.
If any other information is displayed, check the configuration.
4Use the
show axrp command to
check the ring port and its status for
each VLAN group.
If the information about the port and status defined in the network
configuration is displayed for
Ring Port and Role/State, go to No. 5.
If any other information is displayed, check the configuration.
5Use the
show axrp detail
command to check the control
VLAN ID.
If the VLAN ID defined in the network configuration is displayed for
Control VLAN ID, go to No. 6.
If any other information is displayed, check the configuration.
For example, the Control VLAN IDs might be different for each device in
a ring topology.
6Use the show axrp detail
command to check the VLAN IDs
that belong to the VLAN group.
If the VLAN IDs defined in the network configuration are displayed for
VLAN ID, go to No. 7.
If any other information is displayed, check the configuration.
For example, the VLAN IDs that belong to the VLAN group might be
different for each device in a ring topology.
7Use the show axrp detail
command to check the timer value
of the health-check frame sending
interval and that of the
health-check frame hold time.
If the
Health Check Hold Time timer value of the health-check frame
hold time is larger than the
Health Check Interval timer value of the
health-check frame sending interval (i.e., transmission delay is taken into
account), go to No. 8.
If the timer value of the health-check frame hold time is equal to or smaller
than that of the health-check frame sending interval (i.e., transmission
delay is not taken into account), check the settings in the configuration.
