Mitel 5215 and Cisco Auxiliary VLAN - diregard last post

[keywestcity]

We are getting ready to install a mitel voip phone system on our Cisco network. We have been doing some research on how to configure our 4006 layer3 switch but have not found anything that states which config is better over another. From what we've found we should create an auxiliary vlan, set qos(doc refers as cos?) and the document offers different options for the packets (dot1, untagged, etc) Could someone offer a good suggestion which way to setup the vlan on our 4006 for the ip phones.

thank you in advance,

Mike

We found the answer. Basically with Mitel you want to program the 4006 with a trunk and auto speed and vlan:

on the switch

set trunk 3/23 on dot1q

set port speed 3/23 auto

You also have to go into the router and create a vlan for the phone system:

interface port-channel1.20

encapsulation dot1q 20

ip address 10.10.20.254 255.255.255.0

no ip redirects

no ip directed-broadcast

The above is an example that would make a Mitel phone work on port 3/23 with vlan 20. the phone would receive an ip address of 10.10.20.x from the dhcp

A couple of other pointers with the mitel systems with regards to QOS:

Phones are configured to mark cos by setting a DHCP option - this should be set to 5 in a Cisco environment.

Ports that link to phones should be configured to trust CoS on the port, and the port for your ICP should be set to mark all traffic as CoS 5 - some extracts from a doc I found once:

Enable QoS globally

Step 1: Enable QoS on the access layer Catalyst 4000,

Cat4k (enable) set qos enable

Configure the Queue Admission Configuration

Step 1: Map the CoS categories to the queues

Cat4k (enable) set qos map 2q1t 1 1 0-1

Cat4k (enable) set qos map 2q1t 1 1 2-3

Cat4k (enable) set qos map 2q1t 2 1 4-5

Cat4k (enable) set qos map 2q1t 2 1 6-7

Configure the IP phone port queuing

Step 1: Configure VLAN trunking set to 802.1q on the port.

Cat4k (enable) set trunk 3/1 on dot1q

Step 2: set the default data VLAN if necessary

Cat4k (enable) set vlan 10 3/1

And for the ICP

Step 1 Set the CoS value to be used for the 3300 ICP port

Cat4k-access> (enable) set port qos 3/2 cos 5
