We recently upsized our internet speed and purchased an ASA 5512 to be able to take advantage of that, as the 5505 was capped at 100mbps. So here's my issue. I'm trying to create the VLANs on the new firewall but I can't seem to assign the same VLAN to multiple ports.
Example from old ASA 5505 configuration:
interface Vlan300
nameif DMZ
security-level 50
ip address 192.168.5.5 255.255.255.0
!
interface Vlan400
nameif INSIDE
security-level 90
ip address 192.168.1.5 255.255.255.0
interface Ethernet0/3
switchport access vlan 300
!
interface Ethernet0/4
switchport access vlan 300
!
interface Ethernet0/5
!
interface Ethernet0/6
switchport access vlan 400
!
interface Ethernet0/7
switchport access vlan 400
On the new firewall I have to create a subinterface for the VLAN, so the VLAN is setup on a physical interface, and it does not allow me to make the same VLAN on a different port. Does anyone know of a way to assign a VLAN from one port to another?
