ICX is not a product of Extreme Networks.<BR /> Sun, 24 Jun 2018 23:55:00 GMT Stephane_Grosj1 2018-06-24T23:55:00Z https://community.extremenetworks.com/t5/extremeswitching-other/dual-mode-and-voice-vlan-not-working-properly-on-brocade-switch/m-p/11829#M2857 Hello, We had cisco callmanager phone system. Using Brocade ICX 7450 switch with following config<BR /> <BR /> <BR /> <BR /> vlan 10 by port<BR /> <BR /> 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<BR /> <BR /> untagged ethe 2/1/19 to 2/1/24 ethe 2/1/37 to 2/1/44<BR /> router-interface ve 10<BR /> <BR /> <BR /> <BR /> vlan 100 by port<BR /> 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<BR /> router-interface ve 100<BR /> <BR /> <BR /> <BR /> <BR /> <BR /> interface ethernet 1/1/29<BR /> port-name DESKTOP-PHONE<BR /> dual-mode 10<BR /> inline power power-limit 15400<BR /> voice-vlan 100<BR /> <BR /> <BR /> <BR /> This worked fine. Phone got correct IP address in vlan 100, PC got correct IP address in vlan 10<BR /> <BR /> <BR /> <BR /> Switching to Mitel phone system this weekend. Created Vlan 90 for the Mitel phones with an address range of 10.8.90.x /24<BR /> <BR /> Still using Vlan 10 (as above) for desktops<BR /> <BR /> <BR /> <BR /> Removed Tagged ports from vlan100. This removed the voice-vlan from each port<BR /> <BR /> <BR /> <BR /> Added tagged ports to vlan 90 <BR /> <BR /> vlan 90 name MID-Mitel_Phones by port<BR /> 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<BR /> untagged ethe 1/1/47<BR /> router-interface ve 90<BR /> <BR /> <BR /> <BR /> New config on port looks like this<BR /> <BR /> interface ethernet 1/1/29<BR /> port-name DESKTOP-PHONE<BR /> dual-mode 10<BR /> inline power power-limit 15400<BR /> voice-vlan 90<BR /> <BR /> <BR /> <BR /> When we plug Mitel phones in they get an address in vlan 10 instead of vlan 90<BR /> <BR /> If we plug cisco phone back in, it gets address in vlan 90 like it is supposed to. <BR /> <BR /> <BR /> <BR /> What am I missing<BR /> Sun, 24 Jun 2018 22:06:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/dual-mode-and-voice-vlan-not-working-properly-on-brocade-switch/m-p/11829#M2857 Rick_Elliott 2018-06-24T22:06:00Z https://community.extremenetworks.com/t5/extremeswitching-other/dual-mode-and-voice-vlan-not-working-properly-on-brocade-switch/m-p/11830#M2858 Hi,<BR /> I think you are on the wrong forum.

I know some IP phones you have to specify for it to understand tagged traffic in the web-gui.
