HP 2530 switches have a known issue in version YA.15.16 of its firmware that can result in incorrect packet length calculation. The error adversely affects SSH keepalive packets and prevents Auvik from successfully logging into the switches.
The issue was resolved in the YA.15.17 firmware.
If your HP 2530 switches are running firmware version YA.15.16, we recommend updating to firmware version YA.15.17 (or newer) so that Auvik can successfully log into the HP 2530 switches.
