ASA5520 with VLAN tagging for CAT3750

Hi all

Let's take a look at the attachments.

We want to manage 2 vlan with the 3750 (layer 3 switch) that is on the inside port. Those 2 VLAN will be use for the 2950 layer 2 switch that is in a DMZ port of my ASA 5520. The fileserver will be in one VLAN and the database in the other. I know that you can make vlan in the 5520, but I don't want to do that on the ASA level. Is the ASA can tag the vlan of the 3750 in trunking mode ?

Does it tag with ISL or dot1q ?

Thanks you very much

Hi

The ASA will tag with 802.1q and yes you can use 802.1q tagging with the ASA. See the attached link for configuration details
