Usage Guidelines

An active port is defined as one with a link up. If the link goes down, the two entries are automatically deleted.

Two history entries are generated for each device:

  • A sampling of statistics every 30 seconds
  • A sampling of statistics every 30 minutes

The history data can be accessed and displayed using any of the popular RMON applications.

The no form of the command removes the configured RMON history control.

Examples

The following example configures the RMON history. 

device(config)# rmon history 1 interface ethernet 1/1/1 buckets 10 interval 10 owner nyc02
