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.

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 "
."
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.
Analysis Flow
Any failure on node 
constituting ring network or 
port as ring port?
Any failure on cable 
or hardware?
Any failure on software?
Replace the faulty 
parts.
Correct the problem 
on hardware 
configuration.
Execute the dump 
command and collect 
the failure information.
Correct the problem 
on settings.
