Chapter 21 Configuring RMON

Collecting Group History Statistics on an Interface

You must first configure RMON alarms and events to display collection information.

Beginning in privileged EXEC mode, follow these steps to collect group history statistics on an interface.
This procedure is optional.

To disable history collection, use the no rmon collection history index interface configuration
command.

This example shows how to collect and show RMON history for the owner root:

ML_Series(config)# interface gigabitethernet1

ML_Series(config-if)# rmon collection history 2 owner root

ML_Series(config-if)# end

ML_Series# show rmon history

Entry 2 is active, and owned by root

Monitors ifIndex.393217 every 1800 second(s)

Requested # of time intervals, ie buckets, is 50,

Command

Purpose

Step 1

configure terminal

Enter global configuration mode.

Step 2

interface interface-id

Specify the interface on which to collect history, and enter
interface configuration mode.

Note

Group history statistics do not work on

Ethernet interfaces.

Step 3

rmon collection history index

[buckets bucket-number] [interval seconds]
[owner ownername]

For index, identify the RMON group of statistics. The range
is 1 to 65535.
