Extreme 210

Extreme 210

Hello all

I have a customer with old 210 units. They said that they had to program all of their ports as trunk ports in order to allow a PC (untagged) and a phone (tagged) to Co exist on the same port...

They also needed to know if the port was a PC only port, a phone only port or a phone and pc port.

Is there not a way to have the port set up so that it has tagged voice and defaulted vlan for data?

That way it doesn't matter what I plug in, it will work with any combination?

And set as an access port?

RE: Extreme 210

So that is effectively what you have. One untagged VLAN (the Native or Access VLAN) and a single tagged VLAN that is the Voice VLAN.
The IP phones need to discover the Voice VLAN tag and can do that a number of ways - CDP, LLDP, DHCP vendor options (provided by the access VLAN DHCP scope meaning the phone does a 'double DHCP boot') or manually hard-coded.
If it was a Cisco switch it would be an access port (switchport mode access) with a Voice VLAN (switchport voice vlan xx). However the end result is the same - you have an untagged access/Native VLAN and a single tagged Voice VLAN. If you plug a PC in it will connect to the access VLAN. If you plug an IP phone in then as long as the network is provisioned correctly (CDP, LLDP or DHCP) then it will use tagged frames.
