# Configure RMON to gather statistics for interface GigabitEthernet 2/0/1. 

<Sysname> system-view 

[Sysname] interface GigabitEthernet 2/0/1 

[Sysname-GigabitEthernet2/0/1] rmon statistics 1 owner user1 

After the above configuration, the system gathers statistics on packets received on GigabitEthernet 

2/0/1. You can view the statistics in any of the following ways: 

z 

View the statistics of the interface with the display command. 

<Sysname> display rmon statistics GigabitEthernet 2/0/1 

EtherStatsEntry 1 owned by user1-rmon is VALID. 

  Interface : GigabitEthernet2/0/1<ifIndex.3> 

  etherStatsOctets         : 21657     , etherStatsPkts          : 307 

  etherStatsBroadcastPkts  : 56        , etherStatsMulticastPkts : 34 

  etherStatsUndersizePkts  : 0         , etherStatsOversizePkts  : 0 

  etherStatsFragments      : 0         , etherStatsJabbers       : 0 

  etherStatsCRCAlignErrors : 0         , etherStatsCollisions    : 0 

  etherStatsDropEvents (insufficient resources): 0 

  Packets received according to length: 

  64     : 235       ,  65-127  : 67        ,  128-255  : 4 

  256-511: 1         ,  512-1023: 0         ,  1024-1518: 0

Obtain the value of the MIB node directly by executing the SNMP Get operation on the NMS 

through software. 

As shown in 

, Agent is connected to a configuration terminal through its console port and to 

Server through Ethernet cables. 

Gather statistics on received packets on GigabitEthernet 2/0/1 every one minute through RMON history 

statistics table, and thus the administrator can view whether data burst happens on the interface in a 

short time.
