Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

pm (oc)

To configure the pm parameters for OC controller, use the pm ocn command in the config mode. To delete the pm parameters, use the no form of this command.

pm [ 15-min | 24-hour] { ocn} [ report | threshold]

no pm [ 15-min | 24-hour] { ocn} [ report | threshold]
