53.12 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.

" 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 53.15 on page 280.

53.13 SNMP

The SNMP manager server cannot get information from the IP DSLAM.

53.14 Telnet

I cannot telnet into the IP DSLAM.

Table 128 Troubleshooting the SNMP Server

STEPS CORRECTIVE ACTION

1 Ping the IP DSLAM 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 IP DSLAM matches the SNMP

server’s community.

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

(if configured).

Table 129 Troubleshooting Telnet

STEPS CORRECTIVE ACTION

1 Make sure that the number maximum allowed number of telnet sessions has not already

reached. The IP DSLAM only accepts up to five telnet sessions at a time.

Make sure that a telnet session is not already operating. The IP DSLAM only accepts one

telnet session at a time.

2 Make sure that your computer’s IP address matches a configured secured client IP

address (if configured). The IP DSLAM immediately disconnects the telnet session if

secured host IP addresses are configured and your computer’s IP address does not

match one of them.
