Vlan Tgs one one interface

[n.modarresi]

Hello,

suppose there is one ethernet interface contains traffics that comes from different sources( better to say there are aggregated from E1 lines),now i want to find a way to diffrentiate these traffics by VLAN TAGS, is it possible to differentiate traffics by vlan id , is there any switching method to differentiate traffics and capbale to put vlan id to traffics coming from one interface?

thx in advance

I am not sure that I fully understand what you are asking here, but the only way to differentiate traffic by VLAN on a router is to configure a VLAN trunk with subinterfaces for the different VLANs otherwise VLAN information is removed before presenting it to the router.

This is the case:

putting different VLAN IDs to traffics coming from one interface.i think trunking is a way to alow different trafics to come form one interface ,but this case is creating VLANs on one interface.
