Network Asst shows Unreachable: unknown status

[a00181998]

Any idea what's wrong here?

Cisco Network Assistant 5.x shows my newest switch in red—"Unreachable: unknown status", despite everything seeming normal.  All the other switches in my network show good status.

I’m running a small domain with two of the PCs connected to each other via two 3560 switches.  There are no routers in the network.  The switches are connected using the fiber Gb connection.   The connection seems to work fine--I was able to join to the domain the PC connected to the new switch and can ping everywhere in and out of the switch.  However, the topology shows in cisco NA consistently shows the switch as "Unreachable: unknown status", despite show a fat green connection (sorry for the technical jargon). 

After fiddling with it for a while, I gave up, reset the flash and reconfig'd it.  Again, it connected to the domain fine, and I can ping both ways, except Network Assistant still shows it red, "Unreachable: unknown status."

I haven't used NA for a long time and I can't remember if it uses telnet, ssh or snmp to connect to the switches. From your PC where NA is installed, can you telnet, ssh and run an snmp query against the switch in question?

Hi Ian,

How are u doing?

I think CNA uses http/https to communicate with devices.

Hi,

As said in the last reply CNA use http.

You need to verify three things :

- your firmware, make a dir flash :, if the IOS is prefixed with "drwx" then you should have a web dev mgr image and so on http capable switch. You can do more precize checking with a "dir flash:c3....." to see if html directory is present.

- verify that http is enable, "ip http server"

- verify that http authentication match your password policy, "ip http authentication ". enable for enable password (default), local for username commands, aaa for radius/tacacs

Bye.
