Unable to access ASDM

[WilliamHamilton02800]

I have a Firepower2120 utilizing ASA 9.14.2 on a test bench currently connected to a single Management terminal via the Management port.

I am able to access the CLI of the device and ASDM when in the default routed mode. Upon configuring for Transparent mode the config is dropped as expected. After reconfiguring the Management Port and SSH username/password I am able to reach the device via Console and am able to ping it on the Management Port but am unable to authenticate via SSH or ASDM.

What would the next logical step be for this? I've verified the interface, and reconfigured the authentication / Keys already.

If you connected to console post the configuration ? from what IP address you trying to connect ASDM ?

[WilliamHamilton02800]

I'm connected to the Console Port and the Management port currently. I am attempting to connect via the default management IP of 192.168.45.1 (I reconfigured the Port back to the Default IP to help isolate the issue).

i prefer to see the configuration - have you have this config "http 192.168.45.0 255.255.255.0 management"

[WilliamHamilton02800]

My bad misunderstood what you were asking for. I'll post it here, just need a min to reconfig it since I have Org info in there currently. Was trying to import the known good config.

but yes:

"http 192.168.45.0 255.255.255.0 management"

is in there. My Interface looks like this:

interface Management1/1
no management-only
nameif management
security-level 0
ip address 192.168.45.1 255.255.255.0

There is concern on 

no management-only

but I am unable to change it and researching it shows that it is correctly configured anyways.

[balaji.bandi]

If you have configured SSH and http/S config you should be able to get in (with that information it hard to say what is wrong) - if you get a chance post show run (full config)

or watch this video :

[WilliamHamilton02800]

Attached is the Config I am currently working on after wiping my previous one. Since taking this Snapshot I've turned on ASDM history and pointed the Firewall towards the ASDM.Bin file as per step 3 of your link. I'm still watching the video but this is where I am at currently.

high level i do not see ASDM config here : the video is for reference.

# show disk0:

asdm image disk0:/asdm----version.bin (not just ASDM.BIN) 

then try

https://192.168.45.1

[WilliamHamilton02800]

As I posted in the top comment. I directed the ASA to the ASDM.Bin file after pulling that config. It did not correct the issue. Since then I have pulled the .Bin file from the known good and replaced the ASDM.Bin in my test bench and repeated. It did not correct the issue. I've been able to hit the 192.168.45.1 webpage since the start of this. I think it is an authentication issue since I can ping the port, the webpage works, and the "Unable to launch device manger from 192.168.45.1" error is immediate.

Might sound super stupid on my part. But I hadn't actually saved and rebooted the box during my configuration time. I did a quick save / restart and that seems to have cleared it up with no additional configuration changes. Balaji you were super helpful! That guide was really well put together and helped me understand it a bit better too!

 Balaji you were super helpful! That guide was really well put together and helped me understand it a bit better too!

Sure and Glad all went well, you could able to move forward to set up the next goal - this is the best part of the community to help each other and share the knowledge widely what we learning.. Good stuff..!!!!
