Voice VLAN's and IP phones (not Cisco)

[n.oneill]

Hi

We currently have VoIP but QoS is not configured at present. We mainly have 3500XL and 2900XL Enterprise edition switches. Having looked at the docs I think we need to configure a seperate voice vlan and trunking to support CoS end to end. The phones we are using are Mitel 5010 and they support a seperate PC connection.

I am thinking of the following:

int f0/1

switchport access vlan 10

switchport voice vlan 11

Would this send data on vlan 10 and voice on vlan 11?

vlan and how do I check if the phone supports it, is 802.1p support enough?

Thanks

n.oneill,

You will want to check with Mitel to see if they support dot1p; I'm not familiar with that product line. What you have above will send data on vlan 10 and voice on vlan 11. However, the config above "switchport voice vlan 11" supports dot1q. In order for dot1p to work, take out what you have above and you will want to configure "switchport voice vlan dot1p". I hope this info helps!

Thanks for that. It has helped me understand the difference in the configuration options.

We use Mitel sets on 2950s and 2900XLs and here is a sample of our switchport configuration that works whether we plug in an IP set itself, a PC itself, or an IP set with a PC plugged into the IP set:

interface FastEthernet0/10

switchport trunk encapsulation dot1q

switchport trunk native vlan 500

switchport mode trunk

spanning-tree portfast

end

Here, vlan 500 is used by the PC. The IP set picks up an IP address on our voice vlan via DHCP. Note that no voice vlan is specified here:

Name: Fa0/10

Switchport: Enabled

Administrative mode: trunk

Operational Mode: trunk

Administrative Trunking Encapsulation: dot1q

Operational Trunking Encapsulation: dot1q

Negotiation of Trunking: Disabled

Access Mode VLAN: 0 ((Inactive))

Trunking Native Mode VLAN: 500 (LU)

Trunking VLANs Enabled: ALL

Trunking VLANs Active: 1,50,100,102,202,204,208,250,251,253,341,370,498-501,

506,507,600-620,700,701,800,991,992

Pruning VLANs Enabled: 2-1001

Priority for untagged frames: 0

Override vlan tag priority: FALSE

Voice VLAN: none

Appliance trust: none

Self Loopback: No

Hope this helps.

Thanks for the helpful response John.

Could you tell what DHCP option is used to set the vlan used by the phones?

Thanks again!

Here are the DHCP options required. We are using DHCP on a Win2K server and have it disabled on our Mitel 3300. The TFTP server on the 3300 is also being used.

DHCP Option Information

003 – Router Address IP Address, e.g. 192.167.22.251

066 – FTP IP address (same as option 129),for E2T IP Address, e.g. 192.167.22.10

067 – Name of file on FTP server “bootfile”

128 – (Specific) TFTP Server IP Address, e.g. 192.167.22.10

129 – (Specific) RTC IP Address, e.g. 192.167.22.10

130 – (Specific) IP Phone Load “MITEL IP PHONE”

132 – (Specific) VLAN ID (32 bit) 0x2

133 – (Specific) Priority (32 bit) 0x6

For example, our voice vlan is vlan 615 so option 132 contains 0x267 (a Long integer).

Hope this helps.
