150 Using the CMC Web Interface
Troubleshooting the CMC
The CMC Web interface provides tools for identifying, diagnosing, and fixing
problems with your chassis. For more information about troubleshooting, see
"Troubleshooting and Recovery" on page 259.
The following message is
displayed for unknown reasons:
Remote Access: SNMP
Authentication Failure
Why does this happen?
As part of discovery, IT Assistant attempts to verify
the device’s get and set community names. In IT
Assistant, you have the get community name =
public and the set community name = private. By
default, the community name for the CMC agent
is public. When IT Assistant sends out a set
request, the CMC agent generates the SNMP
authentication error because it will only accept
requests from community = public.
You can change the CMC community name using
RACADM.
To see the CMC community name, use the
following command:
racadm getconfig -g cfgOobSnmp
To set the CMC community name, use the
following command:
racadm config -g cfgOobSnmp -o
cfgOobSnmpAgentCommunity
<
community name >
To prevent SNMP authentication traps from being
generated, you must input community names that
will be accepted by the agent. Since the CMC only
allows one community name, you must input the
same get and set community name for IT Assistant
discovery setup.
