and isolate the problem.
Figure 3-4: Analysis Flow
When the Ring Protocol is not running normally or the ring network failure is detected, isolate the problem by
following the failure analysis methods shown in the table below for all the nodes configuring the ring network.
Table 3-15: Ring Protocol Failure Analysis Method
No. Troubleshooting Steps and
Command
Action
1 Execute the show axrp command to
check the Ring Protocol operation state.
Go to No. 3 if "enable" is displayed on "Oper State."
If "-" is displayed on "Oper State," the setting necessary for operating Ring Protocol
is not set in the configuration.
Check the configuration.
If "disable" is displayed on "Oper State," Ring Protocol is disabled. Check the
configuration.
If "Not Operating" is displayed on "Oper State," Ring Protocol is inoperative.
Check to see if any inconsistency (such as combination of operation mode, attribute
and ring port of the system is invalid) exists in configuration. Go to No. 2 if
configuration is valid. [IP8800/S6700] [IP8800/S6600] [IP8800/S6300]
2 Execute the show logging
command to check the normality of the
entry registration to MAC address table
as the default operation of Ring
Protocol
[IP8800/S6700] [IP8800/S6600]
[IP8800/S6300]
Go to No. 3 if the message "The MAC address entry can't be registered at hardware
tables." is not output.
If the message "The MAC address entry can't be registered at hardware tables." is
output, the entry setting for MAC address table necessary for Ring Protocol operation
is failed.
See the corresponding part in the manual "Message Log Reference" and follow
descriptions in [Action]. Also, see "4.1.2 Action to Be Taken When MAC Address
Table Resource Shortage Occurs."
3 Execute the show axrp command to
check the operation mode and attribute.
Go to No. 4 if "Mode" and "Attribute" correspond to the operation mode and attribute
of network configuration.
Otherwise, check the configuration.
