How to configure voice QoS on dell switch
Posted on 2011-09-19
We use Mitel IP phone, and dell 3548P (as pure layer2 switch) as edge switch, and dell PC6248 as Core (layer3) switch. The Mitel by default will put Priority value 6 on all voice traffic, and priority 3 for voice signalling (call control), and chose vlan 100 as voice vlan. My question is on edge switch (3548P), which way is the best to configure QoS for voice, is voice vlan or classofservice; on core switch, which way is the best to configure QoS just for voice.
Highly appreciated your time and help!
