I have a question about the network objects on an ASA running V 8.0(3). After creating an network object with the corresponding netmask in ASDM I cant see it via CLI. Thers just the name without netmask. Where is the netmask stored? How does the ASA deal with this objects and netmasks?
If you configure the 188.8.131.52 address as /8, it should not show as it is a Class A address and this is the default mask for it. /32 mask should show as 'host 184.108.40.206'. But all others should show in the CLI, otherwise how will the ASA differentiate between /28 and /30.
Also please remember ASA uses subnet mask and not wild-card mask.
Oh I get it now, you are confusing the 'object-group' command with the 'name' command.
The 'name' command does not support any netmask whatsoever, it is just like how u do 'ip host' on the router. However personally I hate to use them, firstly its difficult to troubleshoot and view logs, people are usually doing 'show log | inc 10.20.20.20' and they get nothing :), because they are supposed to do 'show log | include ISA-SERVER'. Similarly to date Cisco MARS also does not support it.
The netmask you configure (in ASDM) will be visible by:
show run object-group
and NOT by
show run name
You just CALL that name in the object-group command (if you don't want in to to type the IP address and make configs more readable).
