QoS for voice on a 8212zl

[cepacs]

We have a procurve 8212zl and need to setup QoS for VoIP.  Someone told me that the 8212zl automatically does QoS if you name the vlan "Voice", which we did name it Voice.  Does anyone know if this is true?  I was thinking I'd have to set 802.1p priority on the voice vlan.

The 'voice' designation is for LLDP-MED purposes and notifies a LLDP-MED capable phone of what the voice VLAN on the switch is.  You can prioritize your voice VLAN with 802.1p however that would require a tagged 802.1q infrastructure since 802.1p is carried in the VLAN tag.  If your network infrastructure has that VLAN tagged throughout great, if not then you'd need to look at configuring DSCP.

What would happen if I went into the VLAN Priority and set the 802.1p Priority to 6 for the voice vlan?  That would still require tagging, right?  I'm guessing with LLDP-MED, I would not need to configure anything in the VLAN Priority?

Hi,

If you configure "qos priority 6" under your vlan interface, this will only affect input traffic in vlan 6.

You will need to manually configure each front-panel port for tagging or configure LLDP-MED functionnality by hand for each port  possibily concerned by IPPhone or equivalent.

Bye.
