Someone reported something similar for Netscreen:

It seems that someone at Junpier/Netscreen has been misreading the SSH
protocol spec. Could you file a bug with them so we can figure out which
versions of their products are affected? Once we know this, and their
banner strings (yours is "SSH-2.0-2.0.12") then we can add a workaround.
