I can login to our 2 fabrics using web/java console, but when I try to putty, I do not even get a login prompt.
I've looked through switch admin, and don't see a place either enable or disable SSH - where should I look to try to trouble-shoot this?
Check if the switch has IPfilter configured. You may have a rule preventing you from SSH'ing the switch.
it looks like someone used ipfilter policy to block access to switch via telnet
just login via serial and check policy ,
