QoS on 53xx and 93xx switche

[Kenneth Mogensen_1]

Hi

I have to locations, that are connect to each via fibre.

The two locations are setup as following:

Main:
============
HP Procurve 9308

Voice VLAN
- QoS priority is set to 5
Computer VLAN
Router VLAN to remote office
- With a virtual router interface
- And the command: qos-tos


Remote office:
============
HP Procurve 5308

Voice VLAN
- QoS priority is set to 5
Computer VLAN
Router VLAN to main office
- With a virtual router interface

And in global i have excute the command:
qos type-of-service diff-services

Is this a complete QoS implemenatation ?!?!

I have looked i the VoIP solutions cookbok, but is the above a good solid running QoS implementation ?!?!

Hi
You have Set up a priority Vlan (Voice Vlan) which is good, and the way is correct.
The command "qos type-of-service diff-services" is used to enforce prioritization across WAN
interfaces (the 9300 and 5300), so your implementation is correct.

Good Luck!

Hi again

... I have problems with the above QoS implementation, and i have a question about tagging and untagge the interfaces in the router interfaces ... should they be tagged or untaged ??

Main if untag >-- routing vlan --< untag if remote

or

Main if tag >-- routing vlan --< tag if remote

The priority bit, is preserved on a tagged interface but not on a untag interface, is that true ?!?!

For layer 2 priority bits, 802.1p, the VLANs that you wish to carry this information will need to be tagged. So yes it is true.
