[cisco-voip] HP switches for VoIP (specifically QoS and multicast routing)

[Norton, Mike]

I have looked into using HP switches and came close, but have never actually done it...

My understanding with the voice vlan is that only Cisco switches support CDP for setting the voice vlan. (That's what the "C" stands for.) However, the newish versions of the phone firmware are able to get the voice vlan setting from LLDP-MED, which HP and other non-Cisco switches do support.

Hi guys,



Has anyone had any experience using HP switching infrastructure? Specifically how to configure QoS to trust Cisco phones marking DSCP and COS values.



Can they also be configured to support multicast routing? And if so, can they be configured to join a RP-address on a Cisco voice gateway?



I've also heard that some HP switches do not support Cisco proprietary CDP and you have to manually assign each phones voice vlan? Is there a way of automating this process or is it a hand-on approach to each phone?



Configuration guides and templates would be great thanks.



Thanks all in advance.



Cheers

Dana
