2318 CHAPTER 153: RMON CONFIGURATION COMMANDS

Description Use the display rmon history command to display RMON history control entry and last history sampling information, including bandwidth utilization, number of bad packets, and total packet number.

Related command: rmon history.

Example # Display RMON history entry information for interface Ethernet 1/0.

<Sysname> display rmon history ethernet 1/0

 

History control entry 1 owned by user1 is VALID

 

Samples interface

: Ethernet1/0<ifEntry.642>

 

Sampling interval

: 10(sec) with 10 buckets max

 

Latest sampled values :

multicast packets :0

, CRC alignment errors

:0

undersize packets :0

, oversize packets

Table 611 Description on the fields of the display rmon history command

 

 

 

 

Field

Description

 

 

 

 

History control entry

Index of the history control entry for the interface, 1 in this

 

example

 

 

owned by

Owner of the entry

 

VALID

Status of the entry identified by the index (VALID means the entry

 

is valid, and UNDERCREATION means invalid. You can use the

 

display rmon command to view the invalid entry and with the

 

display current-configuration and display this commands you

 

cannot view the corresponding rmon commands.)

Samples Interface

The sampled interface

 

Sampling interval

Sampling interval

 

buckets max

History table size for the entry, if the specified value of the

 

buckets argument exceeds the history table size supported by

 

the device the latter is displayed.

 

Latest sampled values

The latest sampled values

 

Dropevents

Dropped packets during the sampling period

 

octets

The number of octets received during the sampling period

packets

The number of packets received during the sampling period

broadcastpackets

The number of broadcasts received during the sampling period

multicastpackets

The number of multicasts received during the sampling period

CRC alignment errors

The number of packets received with CRC alignment errors

 

during the sampling period

 

undersize packets

The number of undersize packets received during the sampling

 

period

 

 

oversize packets

The number of oversize packets received during the sampling

 

period

 

 

fragments

The number of fragments received during the sampling period

jabbers

The number of jabbers received during the sampling period. (The

 

support for the field varies with devices.)

 

collisions

The number of colliding packets received during the sampling

 

period
