ip <subcommand>
These commands are used for the Internet Protocol service.
ip address [<addr>]
Display or set the default local IP address. This command
must be given before an 'attach' command if it is to be used
as the default IP address for the interface.
ip heard
Display the ip-heard list. This shows the recently heard tcp/ip
systems. See also the 'ip hport' command.
ip hport [<iface>] [on | OFF]
Display or set the ip-heard facility. If no argument is given,
show the interfaces on which ip-heard is currently active. If
<iface> is given, shows the status of the ip-heard flag for the
given interface. If <iface> <on|off> is given, it will set the
flag on or off. Default is off.
If this flag is on, ip heard frames will be logged in a table.
This table can be shown with the 'ip heard' command or with the
nodeshell 'IHeard' command. Ip-heard logging on ax.25 interfaces
logs all ip stations heard on the port, even if the system wasn't
directly involved in the ip activity. For non-ax.25 interfaces,
only ip frames that we were actively involved in (i.e. that we
routed) are logged. (this difference is due to code internals)
ip hport port1 on
ip hsize [n]
Display or set the maximum size of the Ip heard table. 0 means
no limit. Default=8
ip rtimer [<seconds>]
Display or set the IP reassembly time-out. Default = 30 seconds
ip status
Display Internet Protocol (IP) statistics, such as total packet
counts and error counters of various types.
ip ttl [<hops>]
(B) Display or set the default time-to-live value placed in each
outgoing IP datagram. This limits the number of switch hops the
datagram will be allowed to take. The idea is to bound the
lifetime of the packet should it become caught in a routing loop.
You should make the value slightly larger than the number of hops
across the network you expect to transit packets. The default is
set at compilation time to 255, the official recommended value
for the Internet.
