4.4 Switch Lockout
Note: You cannot log into the switch using the same administrator account
concurrently on different IP routing domains.
You could lock yourself (and all others) out from the switch by:
1 Deleting all IP routing domains.
2 Deleting all port-based VLANs with the CPU port as a member. The “CPU port” is the
management port of the switch.
3 Filtering all traffic to the CPU port.
4 Disabling all ports.
5 Misconfiguring the text configuration file.
6 Forgetting the password and/or IP address.
7 Preventing all services from accessing the switch.
8 Changing a service port number but forgetting it.
Note: Be careful not to lock yourself and others out of the switch.
4.5 Resetting the Switch
If you lock yourself (and others) from the switch or forget the administrator password, you
will need to reload the factory-default configuration file or reset the switch back to the factory
defaults.
