Aruba OS-CX l3-counter interface command

    What is the l3-counters command for, having searched the user guide and also applying to a CX 8325 switch, I can't see where these counters are.

    Is there a command to see the l3-counters?

    At first, I assumed it was #diag in 1/1/52 statistics

    but counters were incrementing in this output before the command.

    Hello Andy, the l3-counters command applies to a Layer 3 interface (thus a routing interface). Directly from documentation: "l3-counters enables counters on a layer 3 interface. By default, all interfaces are layer 3. To change a layer 2 interface to layer 3, use the routing command. The no form of this command, with no specification, disables both transmit and receive counters on a layer 3 interface. To disable transmit (tx) or receive (rx) counters only, specify the counter type you want to disable." so if your interface 1/1/52 is a Layer 2 interface (no routing) then Layer 3 counters not apply.

    Thanks for the info - although I'm still not clear. I read the documentation and tried to apply this on a live switch and found not a material difference in counters. 

    My example is from an uplink VLAN
    Following configuration 
    interface vlan3365
    vrf attach vrf-management
    description Link_to_core
    ip address 10.1.10.116/31
    ip mtu 9100
    l3-counters
    exit


    But when i run the command

    AOX-CX-001(config-if-vlan)# show int statistics | inc vlan3365
    vlan3365 0 0 0 0 0 0 0 0 0 0 0 0
    or
    AOS-CX-001# diag interface vlan3365 statistics
    AOS-CX-001#

    then I tried 
    dtsw-pilot-001(config-if-vlan)# show int vlan 3365

    Interface vlan3365 is up
    Admin state is up
    Description: Link_to_Core
    Hardware: Ethernet, MAC Address: 90:20:c2:bb:32:00
    IPv4 address 10.1.10.116/31
    active-gateway L3 source mac 90:20:c2:bb:32:00

    Statistic RX TX Total
    ---------------- -------------------- -------------------- --------------------
    L3 Packets 5238 0 5238
    L3 Bytes 890017 0 890017


    but there are no tx counters


    So trying to understand where i can make use of the command and the value.

    Hi Andy,

    What hardware and firmware ?

    ------------------------------
    PowerArubaSW : Powershell Module to use Aruba Switch API for Vlan, VlanPorts, LACP, LLDP...

    PowerArubaCP: Powershell Module to use ClearPass API (create NAD, Guest...)

    PowerArubaCL: Powershell Module to use Aruba Central

    PowerArubaCX: Powershell Module to use ArubaCX API (get interface/vlan/ports info)..

    ACEP / ACMX #107 / ACDX #1281

    hi and3p

    I have a 8325 with 10.06.0130 showing this:

    show interf vlan 4

    Interface vlan4 is up
    Admin state is up
    Description: management_4

    A 6400 with 10.07.0010 showing this:

    show interf vlan 1080

    Interface vlan1080 is up
    Admin state is up
    Description: trusted

    An on 6400 with 10.07.0010 and disabled L3-Counters it looks like this.

    show interf vlan 1080

    Interface vlan1080 is up
    Admin state is up

    But sorry, I dont have a 8325 with 10.07.0010. Maybe it is a bug in this combination. Have you tried updating to a newer version? e.g. 10.07.0021?

    Regards
