I'm trying to get my head around the command...
switchport voice vlan dot1p
Here's what I think I understand...
The device and the IP phone use the same subnet.
The phone uses VLAN0
The Device uses Native VLAN of switchport
The phone and device can't see each other because of the VLAN Id Tag because it's not routed.
Dot1p is 3bit of a dot1Q.
Here's what I definetly don't understand...
If dot1p is 3bit of a dot1Q tag then does the port need to be a trunk port?
Can dot1p work with an Access port?
Does dot1p automatically configure the phone with a VLAN ID of 0?
What does all this mean if I have NEC phones compared to Cisco phones?
Why is dot1p recomended to use with non-cisco phones?
In our company we have NEC phones, the phones have to be manually configured with a VLAN ID, we then use a VOICE VLAN with the same VLAN ID, all ports are trunk. this is confusing me as I thought we should be using access ports, but then the dot1p rears it ugly head and I get all mixed up.
Any conformation or clarity will help me immensly
