DHCP relay is started but the phones will not get an IP address from the server on port 48 and I can't see why. Phone is on port 37 just to avoid confusion. I'm probably missing something obvious but ....

Re: ip-helper with Avaya phone system on 2650 switch
Port 1 is missed simply as it's my test config, and the HP software has done one as it's reporting port 37 as being both tagged and untagged for vlan 10 which isn't possible, when in fact it is only tagged (I've reset the config to default and re-entered just to make sure).
I can make the config work by setting the DHCP server to have a NIC on each VLAN and allocate addresses accordingly BUT with the pressure to virtualise I'd only want a single NIC doing the work and have a secondary DHCP server sharing the addresses in event of failure.

Re: ip-helper with Avaya phone system on 2650 switch
do they speak lldp-med? then you need to enable it on the switch with:
vlan 10
voice
exit
wr mem

Re: ip-helper with Avaya phone system on 2650 switch
i am not really good with voip, here is what i mean:
your phones need to know which vlan (10 or 20) to use before making any dhcp requests. As far as i know there are three ways to do so:
1.) configure on the phone <- lot of work in large enviroments
2.)cdp <- doesn't work on hp switches as this is a cisco protocoll
3.)lldp-med <- open protocoll and supported (invented?) by hp
as your are playing in the lab just try lldp-med

Port 48 Isn't tagged aware in vlan 10. Should it be?
