Cant access Cisco CLI through Putty anymore

[Pabsgc]

Hi,

Im using a cisco managed switch to access CLI to practice for my CCNA course, had a password configured and think I failed login a few times and one time it blocked me out. But now it just says "Network error: Permission  denied".

For the record, I had accessed the CLI before and it was working fine (via SSH)

Any idea what I can do to fix this?

details:

Cisco SG300-10 10 port managed switch (connecting to work laptop via ethernet port)

Thanks for your reply

Managed to get in but the password needs to be reset, any easy way to do this?

Hi @Pabsgc 

There are commands that block access after somes failed attempts.

If you can access after restarting the switch, attach the settings to check.
