ProCurve recommends using the default TCP port number (22). However, you
N u m b e r
can use ip ssh port to specify any TCP port for SSH connections except those
reserved for other purposes. Examples of reserved IP ports are 23 (Telnet)
and 80 (http). Some other reserved TCP ports on the switch are 49, 80, 1506,
and 1513.
