Hello, We had cisco callmanager phone system. Using Brocade ICX 7450 switch with following config



vlan 10 by port

tagged ethe 1/1/1 to 1/1/46 ethe 1/1/48 ethe 1/2/1 to 1/2/4 ethe 2/1/1 to 2/1/16 ethe 2/1/25 to 2/1/36 ethe 2/2/1 to 2/2/4

untagged ethe 2/1/19 to 2/1/24 ethe 2/1/37 to 2/1/44
router-interface ve 10



vlan 100 by port
tagged ethe 1/1/1 to 1/1/46 ethe 1/1/48 ethe 1/2/1 to 1/2/4 ethe 2/1/1 to 2/1/16 ethe 2/2/1 to 2/2/4
router-interface ve 100





interface ethernet 1/1/29
port-name DESKTOP-PHONE
dual-mode 10
inline power power-limit 15400
voice-vlan 100



This worked fine. Phone got correct IP address in vlan 100, PC got correct IP address in vlan 10



Switching to Mitel phone system this weekend. Created Vlan 90 for the Mitel phones with an address range of 10.8.90.x /24

Still using Vlan 10 (as above) for desktops



Removed Tagged ports from vlan100. This removed the voice-vlan from each port



Added tagged ports to vlan 90

vlan 90 name MID-Mitel_Phones by port
tagged ethe 1/1/1 to 1/1/46 ethe 1/1/48 ethe 1/2/1 to 1/2/4 ethe 2/1/1 to 2/1/16 ethe 2/1/25 to 2/1/36 ethe 2/2/1 to 2/2/4
untagged ethe 1/1/47
router-interface ve 90



New config on port looks like this

interface ethernet 1/1/29
port-name DESKTOP-PHONE
dual-mode 10
inline power power-limit 15400
voice-vlan 90



When we plug Mitel phones in they get an address in vlan 10 instead of vlan 90

If we plug cisco phone back in, it gets address in vlan 90 like it is supposed to.



What am I missing

Hi,
I think you are on the wrong forum. ICX is not a product of Extreme Networks.
you may want to check the Mitel phones. I know some IP phones you have to specify for it to understand tagged traffic in the web-gui.
