3500 VLAN and uplink with Cisco ASA

I have a L3 switch 3500-48, and I need to set up 4 different VLANs,
I understand Cisco but limited on HP
I am confused with tagged, untagged, no untagged and no tagged options in VLAN configs.

And, my uplink is a Cisco ASA, I dont think I need any VLAn or trunk set up needed in ASA box.

Let L3 switch handle the inter VLAN routing.

In the Cisco switches I can asign a IP address to any ethernet Interface and I can set ASA default gateway to downstream VLANs the conneted interface IP address. How can I do the same in 3500.

Any help would be much appreciated

Almost much the same with HP.
You should create vlan (or use default 1) to communicate with ASA, assing ip address/mask and gw (ASA). Then create any other vlan and assign an ip address/mask to it to route between vlans.

Re: 3500 VLAN and uplink with Cisco ASA

For any uplink that connects 2 devices and is used to carry traffic for multiple vlans, this port should be TAGGED under every vlan.


And for the ports that are defined for a specific vlan, these ports should be untagged members of that vlan, means put them UNTAGGED under that vlan.

By Default every port is untagged member of VLAN 1

Re: 3500 VLAN and uplink with Cisco ASA

no untagged means the command was removed,
it like you configured the untagged for a port then wanted to undo the command so you'll need to put no before it, that's it

no is used to undo whatever command you entered and wants to remove it
