Greetings,
I've recently been tasked with making some of my servers FIPS-compliant. In the process I've run into a problem accessing my sg500x-48p switch via SSH. I get the following error:
no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1
I've searched and found similar issues here and elsewhere which were solved by increasing the size of the diffie-hellman key used to something like 2048 or 4096 with the cli command `ip ssh dh min size 2048`. This command doesn't seem to be supported by my switch though, I've searched the CLI manual and can't find an equivalent command. I've updated my switch to the latest available firmware. According to cisco the switch is still supported but no longer sold. Thanks to any who can offer some insight.
