Hi I could do with a little guidance please.
I am setting up a Cisco switch network for the first time. Having completed a 2 day course 2 months ago I am now the "expert" on site.
I have a network of 6 switches; 2 root, 4 edge, in a mesh configuration.
When accessing via Telnet all is well, and I can access any switch from any port, change configuration etc. but now I have invoked SSH I am unable to access any other switch except the one I am physically connected to: "connection refused by remote host" although I can still ping.
Any pointers please?
Solved! Go to Solution.

Hi Mark
I can access each individual switch using SSH when connected directly (at an edge port) but not over the network.
What does this code set?
ip ssh time-out 60
ip ssh authentication-retries 2
ip ssh source-interface xxxx
and this?
access-class x in

Thanks for your time and input Mark.
I have embarrassingly discovered that typing SSH before the IP address connects successfully.............

Hello
Have you enable ssh correctly / do you have any access-list negating ssh access?
ip domain-name xxxx.com
crypto key generate rsa general-keys ( specify the key size)
ip ssh version 2
line vty x x
transport input ssh

Thanks Paul
Do I need "general keys" here?: crypto key generate rsa general-keys
I have generated keys but without that part.

A little more info............
I have 2 vlans in use, default 1 and vlan 36. All edge ports are assigned on vlan 36.
Could my problem be that I have not set remote span-vlan ?
