Dual Access Ports : Data and Voice
You need to make the port dual-mode port. Configuring a tagged port as dual-mode allows it to accept and transmit both tagged and untagged traffic at the same time. For example, I am going to connect a phone and a laptop to a port 1/1/1. This port is running in dual mode having a tagged membership in VLAN 13 (phone) and untagged membership in VLAN 12 (laptop).
Brocade (config)# vlan 12
Brocade (config-vlan-12)# tagged eth 1/1/1
Brocade (config-vlan-12)# vlan 13
Brocade (config-vlan-13)# tagged eth 1/1/1
Brocade (config-vlan-13)# int eth 1/1/1
Brocade (config-if-e1000-1/1/1)# dual-mode 12 – this command changes from the native vlan to vlan 12 which is for the data port and should be untagged.
I have been working in IT since 2004, but my passion for IT started when I was just a wee boy growing up in Scotland. I have been very fortunate that my passion has allowed me to travel the world and learn a great many things about IT and about life.
I wanted to start this website/blog to give back, to share mainly about Networking what I have learned from many great mentors and what I am learning still today. I have only been doing Networking as a job for 2 years but I have been studying for this career since 2012.
I hope you find the information useful, and I hope I can inspire you just as I have been inspired.
