You can assign different passwords for different routing levels by using the keywords level-1 and level-2. The no form of this command disables the password for Level 1 or Level 2 routing, using the respective keywords level-1 or level-2. This password provides limited security as it is processed as plain text. isis priority Set the priority of the designated router you select. E-Series, S4810 Syntax Parameters isis priority value [level-1 | level-2] To return to the default values, use the no isis priority [value] [level-1 | level-2] command. value level-1 level-2 This value sets the router priority. The higher the value, the higher the priority. The range is 0 to 127. The default is 64. (OPTIONAL) Specify the priority for Level 1. This is the default. (OPTIONAL) Specify the priority for Level 2. Defaults Command Modes Command History value = 64; level-1 (if not otherwise specified). INTERFACE Version 8.3.12.0 Introduced on the S4810. Usage Information You can configure priorities independently for Level 1 and Level 2. Priorities determine which router on a LAN is the designated router. Priorities are advertised within hellos. The router with the highest priority becomes the designated intermediate system (DIS). NOTE: Routers with a priority of 0 cannot be a designated router. Setting the priority to 0 lowers the chance of this system becoming the DIS, but does not prevent it. If all the routers have priority 0, one with highest MAC address becomes DIS even though its priority is 0. 881
