15.4. RMON Commands

Command Purpose

Use this command to enable RMON statistic collection on the interface.

Prerequisites

Command Syntax

rmon collection stats ID ( owner OWNER | )

no rmon collection stats ID

Command Mode

Interface Configuration

Default

None

Usage

To create one statistic only on a certain interface

Examples

This example shows how to collect RMON statistics for the owner test:

Switch# configure terminal
Switch(config)# interface eth-0-1
Switch(config-if)# rmon collection stats 1 owner test

Related Commands

show rmon statistics

Command Purpose

Use this command to enable RMON history collection for the specified number of buckets and time period.

Prerequisites

Command Syntax

rmon collection history INDEX ( buckets NUMBER | ) ( interval INTERVAL |) ( owner OWNER | )

no rmon collection history INDEX

Command Mode

Interface Configuration

Default

None

Usage

Use this command to enable a history statistics on a certain interface.

Examples

This example shows how to enable history RMON statistics on eth-0-1:

Switch# configure terminal
Switch(config)# interface eth-0-1
Switch(config-if)# rmon collection history 1 buckets 1000 interval 100 owner test

Related Commands

show rmon history

Command Purpose

Use this command to add an event to RMON event table.

Prerequisites

Command Syntax

rmon event INDEX ( log | ) ( trap TRAP | ) ( description DESCRIPTION | ) ( owner OWNER | )

no rmon event Index

Command Mode

Global Config

Default

None

Usage

Create an event is for RMON alarm. Permit event special triggered operate. Log can be sent by trap.

Examples

This example shows how to create an event:

Switch# configure terminal
Switch(config)# rmon event 1 log trap public description reach_max owner test

Related Commands

show rmon event

Command Purpose

Use this command to set an alarm on a MIB object.

Prerequisites

Command Syntax

rmon alarm INDEX OID interval INTERVAL ( delta | absolute ) rising-threshold RTHRE ( event numbs | ) falling-threshold FTHRE ( event NUMBER | ) ( owner OWNER | )

no rmon alarm Index

Command Mode

Global Config

Default

None

Usage

We need to create events for rising threshold and falling threshold first before we create an alarm for a mib.

Also the statistics need to be created on an interface, because we only support to set alarm monitor on etherStatsEntry.

Examples

This example shows how to set an alarm:

itch# configure terminal
Switch(config)# rmon alarm 1 etherStatsEntry.3.1 interval 10 delta rising-threshold 1000 event 1 falling-threshold 5 event 1 owner test

        Broadcast packets 0, multicast packets 0, CRC alignment errors 0, collisions 0
        Undersized packets 0, oversized packets 0, fragments 0, jabbers 0
        # of packets received of length (in octets):
