This is driving me nuts. I cannot seem to get qos working.
We have a couple of Avaya IP Office units that use a diffserv code point of 46 for voip. If I use the same code point in a simple configuration our procurve switches don't seem to prioritise it.
Here is the first basic config that we used.
; J8165A Configuration Editor; Created on release #H.10.38

hostname "Fred"
snmp-server contact "The Boss"
snmp-server location "Computer Room"
interface 49
name "Inter Office Link"
speed-duplex 100-full
exit
snmp-server community "keepout"
vlan 1
name "DEFAULT_VLAN"
untagged 1-50
ip address dhcp-bootp
exit
qos device-priority 10.1.0.24 dscp 101110
qos device-priority 10.1.7.24 dscp 101110
qos type-of-service diff-services

But this doesnt work nor does the one below.
Running configuration:

; J8165A Configuration Editor; Created on release #H.10.38

hostname "Barney"
snmp-server contact "The Boss"
snmp-server location "Comms Room"
interface 7
name "IP Office"
exit
interface 49
name "Inter Office Link"
speed-duplex 100-full
exit
snmp-server community "keepout"
vlan 1
name "DEFAULT_VLAN"
untagged 1-50
ip address dhcp-bootp
exit
vlan 2
name "IP_Office"
no ip address
qos priority 6
tagged 7
voice
exit
qos type-of-service diff-services

The Avaya units use lots of broadcast traffic. I want to make sure that the broadcast traffic doesnt go down our 100mb inter-office connection and that our voip traffic gets the highest priority.

What do i need to do to get it working?

Thanks.
 
What type of IP Office are you using? Are you sure the diffserve is set correcly in the IP Office? Seen it often not being set correctly.

There is also a whitepaper available on the avaya site how to configure the HP switches. Follow that doc and you should be ok.

qos dscp-map 100010 priority 6 is there recommendation..

Good luck!
