Upper boundary for the range of dynamic UDP and TCP ports. The smallest
acceptable range, between the lower and upper boundaries, is 500.
When needed, the TCP/IP implementation of the unit randomly selects a dynamic
port amongst the free ports of the range.
For example, the dynamic ports range is configured from 41000 to 42000. The unit
needs to download a new version of its software. The TCP/IP implementation of
the unit selects a local UDP port for the TFTP client. The port is selected in
the dynamic ports range so the port has a value between 41000 and 42000.
The UDP and TCP ports are separated in three ranges: well-known ports (0 to
1023), registered ports (1024 to 49151) and dynamic ports (49152 to 65535). The
IANA (Internet Assigned Numbers Authority, www.iana.org) assigns the well-known
ports. The IANA also lists the registered ports. The dynamic ports are not under
the authority of the IANA. Most TCP/IP implementations use the range 1025 to
65535 for dynamic ports instead of the range defined by the IANA.
This variable?s semantics are different depending on protocol and/or
hardware platforms.
