CentOS does support port based VLANing from your definition. Meaning you can configure the NIC to use 802.1q-VLAN-tagging and add the required VLAN-information to the ethernet frame. The interface ... [by tigalch]
I am trying to make sure Vlan tagging is correctly configured on our Cisco Switches. I've been seeing considerable network slow down and suspect its due to our camera traffic entering the data Vlan. We separate traffic, Vlan 1 = data, Vlan 3 = Camera.
My question is this, What is the difference between Port to Vlan and Vlan to Port?
I'm Confused from the fact that Vlan tagging is done at access port and trunk port always gets tagged packets (until its case of native vlan).But I still believe in other fact which says tagging happen only when a frame hit the trunk port which means trunk port gets untagged frame and tagging is not possible at access port.
Would like to know where actually this tagging happens ?
