Hey Guys, I had a question about a certain set-up that is coming up. We have a small office going live soon and the set-up is as follows. Our network connection coming in will be linked to a Cisco ASA5505 that will serve as a DHCP client for 2 VLAN's.This will link to a 2960 which will feed Avaya IP Phones and computers on the same link. My question is, is it possible to have 2 DHCP sets on the ASA that serve each VLAN. If so, what is the set-up to do that. Also, on the switch side, what is the set-up for each link? Obviousley they need to be trunking but what else? Thank you so much for your help.
Thanks. I guess for more detail this is what i am trying to do.
ASA will have 2 DHCP ranges, 10.2.25.x - x, and 10.2.27.x - x. This ASA will link to a 2960 switch and off of each port will be an Avaya IP phone and a computer. Computers get the 25 range and phones get the 27 range.
Usually, your voice vlan is different then your data vlan. So, yes, you need two different vlans with 2 different DHCP scopes. And yes, the switch will have a trunk link to the ASA. You also need a management vlan/ip to manage the switch.
Now I set the ethernet 0/1 on the ASA to trunking and it should trunk both of these VLAN's? What do i do on the switch for configuration other than setting the uplink as a trunk? Do I need to do any native vlan config? Do i set all trunks on the switch as trunks then? How do the computers know which address to pull?
