I have two Cisco Catalyst 2960-S 48-port switches 'stacked' using the Cisco FlexStack module. Originally I had to set them up using 'Express Setup', which I absolutly hate from my limited use of it.
I configured hostnames, ip addresses, and made sure the stack was functioning properly. I tested by plugging in a laptop and making sure it could open an internet page and all was well. I configured each switch exactly the same with the exception (obviously) of the hostname and IP. I then powered them OFF and installed the stacking module and they auto-configured themselves..
Before:
Switch-A (192.168.10.3)
Switch-B (192.168.10.4)
After:
Switch-A (192.168.10.3) Master 1
Switch-B Member 2
What I need and want to do now is setup remote access. If I have to go connect up with a console cable to configure that's fine, but I'm not sure if I need to..
If I open PuTTY and use Telnet to connect it states 'password required, but none set' and the PuTTY window closes.
If I open PuTTY and use SSH to connect it prompts me 'login as:'
If I press enter (@192.168.10.3's password:) it proceeds to prompt me for a password, which entering the password I used to setup the switch I receive 'access denied'.
I know I didn't configure SSH or Telnet for that matter when I initially set these up. I want to fix that now.
I want SSH (v2) enabled and I want to disable Telnet.
Any suggestions?
It appears that the switch needs to have a new key generated to using a greater length than 1024. 32 bit key generator url safe. However when I try this, certain crypto commands seem to be missing. For example when I try 'crypto key generate rsa modulus 2048' it says invalid input.
