sf300 - vlan bandwidth management

[bob reiber]

i have a small network with Polycom phones connected to the sf300 switch and have the pc's daisy chained via the second switch port on each phone. i have the pc traffic running on the default vlan 1 and the voice traffic running on the voice vlan 100. can i do bandwidth management on a vlan/port basis or is that not necessary. i want to ensure that the voice traffic is never impacted by the pc traffic on the same cable.

Hello Bob,

Yes, You can..

You can mark the traffic comming from the phone ( DSCP values) so you can provide priority to that

An easy way to configure that is to use the auto-qos configuration method

Hope I could help

Hi Bob, here is a documentation that should help you.

Make sure to use the 1.1.2.0 code at the minimum. The switch supports auto voice vlan, with the auto voice vlan, it takes care of the QoS for you. Since you're using Polycom phones, I'd recommend to follow the documentation on the link below.

If you're having problems with extension to extension calls, it is a layer 1 or layer 2 issue most likely. If you're having issues with LAN to external user calls, that is a firewall or ISP/ITSP issue.
