Procurve QoS

[MrJDH]

We have a variety of ProCurve switches within the building. We are currently preparing our network for a VoIP telephony system.

I’ve noticed that around 50% of the switch models feature a variety of QoS options, compared to a ‘slimmed’ down offering of QoS options on the remainder of the switches.

For example, our 2610, 2626 and 2650 models offer:

- Application Type

- Device Priority

- Type Of Service

- Protocol

- VLAN priority

- DSCP Policy Table

- DiffServe TOS

Whereas, our 2510, 2510G and 2510B models only offer;

- Type Of Service

- DSCP Policy Table

- DiffServe TOS

This is fine, as the 3 options above appear on all switches.

In terms of setup for VoIP, all switches feature the ‘Voice VLAN’ option, which I have already enabled for the VLAN created for the phone network. From reading, I believe that enabling the Voice option for the VLAN will auto set the CoS priority to 7 – confirmation would be good?

The 2510, 2510G and 2510B models support QoS, but don’t offer for the ‘Voice’ option to be enabled for the VLAN in the CLI. This is fine, as it can set the same parameters through the webmin. As the ‘DSCP Policy Table’ QoS option appears on all switches, this is what I would use.

 

Q. Do I simply select the correct DSCP codepoint, and then set the 802.1p priority to 7?

Thanks.
