Setting up Qos on an HP Switch

Last Modified: 2015-08-09

We are using HP ProCurve 2910al-48G ethernet switches.  At my work we network 2 separate locations that are connected via a 10 mbps fiber point-to-point connection.  Lets call the primary office = Office#1 and the secondary office = office#2.

I probably should mention that we are a small company with 32 employee and Office#2 will have 5 employees at the most at any given time. Hence, the majority of the fiber point to point traffic, during business hours, is used for telephony.  For the past year we have been replicating backups from Office#1 to Office#2 using the fiber point-to-point connection during the evening hours.  I have scheduled the replication to transfer the data at full blast (10 mbps) at 11:00 pm - 7:00 am.  the other times (8:00 pm - 11:00 pm it is set to replicate at a lower rate 7.0 mbps).  The problem that we are dealing with is that once every month the Phone system at Office#2 is non-functional and it must be restarted.  I can do that remotely, I can connect to the appliance from Office #1 and remotely restart the appliance.  The everything is fine again; but, I should not have to remotely restart that appliance once every 2-3 months.

The telephony vendor stated that we should enable QoS on the ethernet switches.  We already have that on the Office#1 switch; but, not on the Office#2 switch.  Please see some configurations below.

Office#1 switch
vlan 101
   name "Office1_Voice"
   untagged 2-4
   qos priority 5
   ip address XX.XX.X.254

Office#2 switch
vlan 102
   name "Office2_Voice"
   untagged 3
   ip address XX.XX.X.254

To properly utilize QoS will QoS need to be configured on both the switches at both locations?  I am just wondering what I can do to help prevent the telephony system from going down and then needing a restart every once in a while.  This never happened before we began replicating our backups to Office#2.

It it is required to setup QoS on the Office#2 switch tehn how may I do that?  I did not setup QoS on the Office#1 switch.
