TitleHow to monitor traffic in and out of a VLAN?
Objective
Monitor traffic in and out of a VLAN via SNMP in order to graph it with NMS software?
Environment
  • EXOS
  • SNMP
  • NMS
Procedure
  1. Enable VLAN monitoring on the VLANs you want to graph.
configure ports all monitor vlan <vlan_name>
 
  1. You then can see the VLAN stats with the below command.
show vlan statistics no-refresh
 
  1. Depending on the VLAN tags the OID's will be different per VLAN.  With the below OUIs you can just do a SNMP "get next" to find the correct VLANs.  The numbers will match the "show vlan statistics no-refresh" command.
Received Counters:

Name extremePortVlanTotalReceivedFramesCounter

OID .1.3.6.1.4.1.1916.1.2.8.2.1.8

OID .1.3.6.1.4.1.1916.1.2.8.2.1.7

        4. you can check the Vlan Name Index for the monitored Vlans by using the following MIB and OID
