Use this command to configure an authentication password for the interface.
| password | Specifies an authentication password for the interface. |
| level-1 | (Optional) Specifies that the configured password is applied to level 1 for the interface. |
| level-2 | (Optional) Specifies that the configured password is applied to level 2 for the interface. |
If an IS-IS level is not specified, the level type defaults to both level 1 and level 2.
Interface configuration.
Entering a password on an interface overrides any device level key chain or password configuration for the interface. Both a key chain and password can not coexist on an interface. If a key chain configuration already exists on the interface, it must be removed before configuring an interface level password.
The “no” form of this command removes the IS-IS password configuration on the interface.

System(rw)->configure System(rw-config)->interface vlan 100 System(rw-config-intf-vlan.0.100)->isis password password System(rw-config-intf-vlan.0.100)->
