VLAN Priority

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
lldp top-change-notify 1-22
vlan 1
   name "DEFAULT_VLAN"
   no untagged 23-24
   untagged 1-22,25-28
   ip address
vlan 16
   name "Voice"
   untagged 23-24
   tagged 1-22
   ip address


Re: VLAN Priority

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.
