Hi Guys, need your help. I have a newly purchased Cisco5510 and I am configuring it as usual from the other high end ASA. But from this ASA, I cannot create a subinterface and cannot configure nameif from the main interface. Is it really a behaviour of Cisco5510?
Another problem I have is, I have downgraded the IOS from Version 9.0 to 8.25 as per our company standard. I was able to load the ios and boot to this IOS, however upon checking, the software version is still 9.0.
Are you sure that you have configured the "vlan" under the sub interface before you try to configure "nameif" or any other parameters? I wonder if having the firewall in Transparent mode would affect this also? Or is the firewall in its default Routed mode?
Also with regards to your software level problem. I would presume that the problem is that you have not removed the higher level software from the boot settings
Try the command
show run boot
If you can see the file for the software 9.0 mentioned then remove it. It might be first on the list and then after that the 8.2 and because of that the new software might still be booting up.
Firewall didn't accept "interface eth0/0.100" or any other subinterface, same thing when I go to main interface and try doing nameif, no available syntax for that.
With regards to IOS, yes I removed the previous IOS, from the show bootvar, it shows 8.2 image only. Actually, when I reload the firewall, it shows it is loading from 8.2 image. I will share the result once back to office.
You wont be able to create subinterfaces on the ASA5505 model as its a firewall with a built in switch module. Therefore it acts like a L3 switch and you configure Vlan interfaces instead of subinterfaces of actual physical ports. Seems there was some missunderstanding related to the ASA model. ASA5505 has switch ports and you can configure Trunk interfaces with the proper license (Security Plus). No other basic ASA model (other than the FWSM and ASASM) support Vlan interface to my understanding.
Depending if the ASA is using Base License or Security Plus license your allowed Vlan interface limit may vary. On the Base License its 3 vlans (of which one is resricted) and on Security Plus I think the limitation was 20 Vlans.
