  • 1.  snmp get , show interface traffic less than spirent testing

    I found, use SNMP to get interface traffic counter and show interface traffic, less than actual traffic usage. these may not include ethernet mac header,ethernet  Preamble, an Interframe gap, and so on. 

     

    for example, I use Spirent test 10G traffic, the result of physical traffic is 10G, show interface xe-0/0/3 , it only shows 9.5G. If I use 128byte packet 10G testing. it shows almost 8.6G on the switch

     

    is there any command and SNMP OID can monitor actual traffic usage include them?

    account-layer2-overhead , try this option. Or you can try same option in interface hierarchy 

    show configuration interfaces  
    ge-1/0/1 {
        unit 0 {
            account-layer2-overhead {
                18;			 adds 18 bytes per packet to interface statistics
            }

    it doesn't support switch products, it only supports routers.
