Cisco ASA Security Levels

Hi Juan,

The main difference between the 5505 and the 5510 or higher is that the 5505 has switchports and VLAN interfaces. The 5510 only has L3 interfaces.

Configuration is similar to a L3 switch, here’s an example for an INSIDE and OUTSIDE:

ASA(config)# interface vlan 100
 ASA(config-if)# nameif OUTSIDE
 ASA(config-if)# security-level 0
 ASA(config-if)# ip address 192.168.1.254 255.255.255.0
 ASA(config-if)# no shutdown

 ASA(config-if)# interface vlan 200
 ASA(config-if)# nameif INSIDE
 ASA(config-if)# security-level 100
 ASA(config-if)# ip address 192.168.2.254 255.255.255.0
 ASA(config-if)# no shutdown

 ASA(config)# interface ethernet 0/0
 ASA(config-if)# switchport access vlan 100
 ASA(config-if)# no shutdown

 ASA(config-if)# interface ethernet 0/1
 ASA(config-if)# switchport access vlan 200
 ASA(config-if)# no shutdown

The 5505 is the last ASA that uses these switchports and VLAN interfaces, the 5506 has 8x L3 interfaces.

Hope this helps!

Rene
