I am setting up 30 switches for a remote site. Everything seems to be working fine. I can ping any switch extremely quickly with 1-3ms response times. However, when I try to SSH to a switch it takes 20+ seconds, and during that time the switch management interface stops responding to pings. What could be causing this?

Thankyou for sharing the info above.What firmware version is running on each switch ? This looks like a TAC scenario, you might need to share the wireshark output and they will be further able to assist with the issue.

Try to get one Linux/UNIX box, enable ssh login debug from that Linux/UNIX host:
ssh -vvv -l admin ip-of-that-switch-which-got-issue
Half duplex issue?
ethtool -v eth0
Are there any ip firewall between your client and switch?
As far as I know we do not need to care for DNS reserve query config for SSH daemon on Borcoade switch.
If you are using director, maybe you can try hafailover.
