Cisco 3750 Issues with Network Assistant

[SF02]

I have two stacks of 3750 switches with the following configuration:

1:ws-c3750g-12s

2:ws-c3750g-12s

3:ws-c3750g-12s

4:ws-c3750g-48ts

5:ws-c3750v2-24ts

I have just upgraded the software to the Cryptographic Services image in order to use SSH rather than telnet for CLI management. The image I am using is c3750-ipbaselmk9-tar.122-55.SE4 and it was upgraded using the tarball with archive download-sw.

I have enabled SSH and HTTPS using the following commands:

ip domain-name xxxxxx

crypto key generate rsa

ip ssh version 2

ip ssh time-out 60

ip ssh authentication-retries 3

line vty 0 4

transport input ssh

line vty 5 15

transport input ssh

no ip http server

ip http secure-server

ip http authentication local

I can now SSH to the stack CLI and use HTTPS from a web browser but when trying to connect with Cisco Network Assistant I get an unable to connect message. The only way I have been able to get this to work is to enable ip http server. Has anyone else encountered this issue and knows how to resolve?

Thanks,

Phill

Hi,

I can't see anything in the documentation you have linked which refers to the problem I am having. Can you be more specific please.

Thanks,

Phill

I have had the same issue, with the newer version of Network Assistant. I get the message on my 3750's, 2960 switches, which are running IOS 122-53.SE2 with Web device Manager. This is with Verison 5.7 that I get this all the time. I ended up down-grading to the 5.6 which does not give me this problem. I believe there is something wrong with the 5.7 version that is preventing any https connections to switches. CISCO NEEDS TO FIX the PROGRAM.

I'm glad it's not just me, I noticed today I am also getting this issue on my aironet APs. I recently updated to 5.7 of CNA before I began moving to using SSH and HTTPS.

I will try downgrading to 5.6 and confirm if this resolves the problem for me.

Cheers,

As per what krhashbarger posted, I downgraded CNA to 5.6.3 and this now works for all my HTTPS devices.

I agree that this seems to be a problem with version 5.7 which needs to be addressed by Cisco.

Thanks for the help.

No problem, glad to help. Hopefully Cisco will come out with a fix soon for this problem.
