VLAN Priority

  • 1.  VLAN Priority

    Posted Feb 21, 2018 01:34 AM

    I configured my Aruba 2530 with VLAN an LLDP-MED.

    Now I found out, that LLDP-MED will distribute a VLAN-priority, but my devices are sending DSCP, so I don't know it's a good idea to priorise the whole VLAN.

    What's here the behavior? I guess, that now also for example FTP-software-updates in this VLAN will priorised, but that's for me not the idea behind a clear priorising of VOIP.

    This is the actual configuration:

    qos type-of-service diff-services
    ip default-gateway 192.168.1.1
    lldp top-change-notify 1-22
    vlan 1
       name "DEFAULT_VLAN"
       no untagged 23-24
       untagged 1-22,25-28
       ip address 192.168.1.10 255.255.255.0
       exit
    vlan 16
       name "Voice"
       untagged 23-24
       tagged 1-22
       ip address 192.168.16.10 255.255.255.0
       voice
       exit

    With priority distribution via LLDP-MED you can more or less automatically configure the end device. If you have one VLAN just for voice you can potentially use the priority on the complete VLAN. If you are fine with DSCP forwarding coming from end-devices and they map you're configuration you can also just adapt these and not override them.
