I've got an issue I hope someone can help with. I have 2 x 4510 Catalysts and 1 x 4506 Catalyst switches that have been relocated within my estate. Since the move my LMS 4.2 seems to be unable to perform a config collection or carry out any sort of netconfig job on those three devices.
LMS is set to use SSH and if I check by using PuTTY from the server or my own PC all is ok but when I try a "reachability status" check I get the following
"Could not detect SSH protocols running on the device TFTP is not supported as a connection protocol for VLAN Fetch, Only TELNET and SSH are supported as connection protocols for VLAN Fetch TELNET: Failed to establish TELNET connection to x.x.x.x - Cause: Connection refused."
I've tried to delete the devices and re-add them but it's made no difference.
SSH is obviously running ok as I can PuTTY from anywhere else it's just the LMS application itself which can't connect
Are you using TACACS to device authentocation ?
Are there any Custom prompts configure on the device like :
If yes then open the TACACSPROMPT.ini file (NMSROOT/CSCOpx/objects/cmf/data )
The Tacacsprompt file will have the following entries:
PASSWORD_PROMPT=Password:Add your prompts in the file and see how it woorks.. This could be one of the reason for failure.
I hope this will help
Hi and thanks for the quick reply.
No, I don't use TACACS, just SSH with RADIUS authentication on Windows NPS which all works from every other location (even the desktop of the server running LMS 4.2.1)
