32.6 System Lockout

Any of the following could also lock you and others out from using in-band

management (managing through the data ports).

1 Deleting the management VLAN (default is VLAN 1).

2 Incorrectly configuring the CPU VLAN.

3 Incorrectly configuring the access control settings.

4 Disabling all ports.

Note: Be careful not to lock yourself and others out of the system.

If you lock yourself (and others) out of the system, you can try using the console

port to reconfigure the system. See Section 32.9 on page 242.

Table 97 Troubleshooting the SNMP Server

STEPS CORRECTIVE ACTION

1 Ping the VOP from the SNMP server. If you cannot, check the cable,

connections and IP configuration.

2 Check to see that the community (or trusted host) in the VOP matches the

SNMP server’s community.

3 Make sure that your computer’s IP address matches a configured trusted host

IP address (if configured).
