configure isis password vlan
This command sets or clears the authentication password for one or all IS-IS VLANs.
|vlan all||Applies the password configuration to all IS-IS VLANs.|
|vlan_name||Specifies a single VLAN to which the password configuration is applied.|
|none||Clears the password configuration and disables hello PDU authentication.|
|encrypted||Specifies that the supplied password is encrypted and must be decrypted prior to using it in a TLV.|
|password||Specifies the password. Passwords may be up to 254 alphanumeric characters in length.|
|level [1 | 2]||Limits the password configuration to level 1 or level 2. If neither level 1 or level 2 is specified, the configuration applies to both levels.|
If configured, the specified password is included in Hello PDUs for the specified level. In addition, received Hello PDUs on the specified interface are authenticated with the same password. Hello PDUs that are not authenticated are discarded.
Only plain text passwords are supported. Note that if the password is changed on an interface with an existing adjacency, the neighboring router needs to be configured as well. Depending on how timers are configured, the adjacency may time out while transitioning between passwords. Although passwords appear in plain text during configuration, they are displayed and saved in encrypted form.
The following command assigns password Extreme to all level 1 VLANs configured for IS-IS:
configure isis vlan all password simple Extreme level 1
