I have a interesting problem
8 port cisco 3750G switch, access with SSH from core switch 6509E. direect access from MacOS no go because of old SSH security protocol.
When I try to enable privilege mode there is a problem
typing "enable" <enter>, this will lockout terminal input until the enable password has a timeout.
it gets worse, from the 6 3750G 8 port switches, 3 have this problem.
Has anyone experienced this ? Any solution?
thanks

- I presume the ssh from the 6509 may have limited capabilities too, I would advice a 'stronger' ssh-client, try for instance from a linux box.

- I would give it a try anyway, see what happens, if errors seen, post here.

thank you for your reply but Cisco release 12.2 only supports "old" ssh security.

hi Marce1000,
I managed to get putty installed locally and despite the warning on SSH encryption being depreciated I managed to get into the switch and was able to issue the enable + password command.
It seemed that trying ssh from several other switches in that network they all locked up.
Thank you all for your support

make a username with priv 15 and you won't need to enter enable password

thank you for your reply but to setup private 15 access I first have to get into these switches in Enable mode

Wow, 12.2(37)SE.
Check the logs and see if there are any duplicate IP addresses errors.

One to mitigate the issue, user has 15 priv can fix the issue, if the user has other priv - then what is the ssh version running on switch ?
show ip ssh give you information.

sorry but I took over remote management of these switches and only one account exists
SW05#sho ip ssh
SSH Enabled - version 1.99
Authentication timeout: 120 secs; Authentication retries: 3
I can only access these switches remotely as I'm not physically in the same location as these switches
06-13-2021 04:53 AM
what priv level that user ?
can you post show run

Hi, thank you for your feedback
I wish I knew as without getting into enable mode you cannot run this command.
