I am trying to configure sub interfaces on a Cisco ASA running v7.2 but it will not let me use the sub interface command?

Hi,
If you have an interface say it gigabit ethernet 0/1 in order to create a subinterface of gigabitethernet 0/1 you have to issue the command:
interface gigabitethernet 0/1.x where x is a number (say it 1..for example)...
I hope this help.s
Best regards.

I tried that but I get the following
ciscoasa(config-if)# int ethernet0/0.100
^
ERROR: % Invalid input detected at '^' marker.

check your license - do you have a ASA5505 ?
04-07-2009 06:27 AM
Yes, which license should I have?

To be above to trunk and use sub-interfaces you need "Security Plus" Which allows for 20 vlans and trunking support.

I got similar problem.
My ASA says ethernet instead of Giga.
I def have Security Plus license, Check in "about" via ASDM.
Please help.

Because ASA 5505 only have ethernet ports not gig ports.Here's the datasheet:

Thanks, it is ASA 8.2
But I did that:
ciscoasa(config)# int e0/0
ciscoasa(config-if)# no nameif
ciscoasa(config-if)# no sec
ciscoasa(config-if)# no security-level
ciscoasa(config-if)# no ip ad
ciscoasa(config-if)# no ip address
and got this when trying to create subinterface:
ciscoasa(config)# int ethernet 0/0.1
^
ERROR: % Invalid input detected at '^' marker.
Any ideas?

you create a vlan interface, then assign the physical interface to the vlan.
Int vlan x
Interface fa0/0
Switchport access vlan x

You cannot create sub-interfaces on the physical interface on the ASA 5505 but you would need to create vlan interfaces as specified above.

I thought that with security plus license I can?
Basically I need outside interface to listen on more than 2 public IPs.
As outside interface is on /28 network.
If I create config as Andrew adicesed, will that work?
