Arp - Digi PortServer/8 User Manual

arp

Syntax: [ range= range]
set arp
set arp ip=
set arp range=
This sets or displays the arp (Address Resolution Protocol) table entries. The arp table maps IP
addresses to Ethernet addresses. In most cases, this is done automatically by the ARP protocol
and manual modification of this table will not be required. Making changes with ARP requires
root priveledges. The arp options are:
range
set arp range=
If the set arp command is entered with no options other than a range, the current
ARP table entries for that range are displayed. ( set arp with no range prints the
entire table.)
ipaddress ether= ethernetaddress [ tim2liv= time]
set arp ip=
The second form of the set arp command is used to add a new entry into the ARP
table. Set ipaddress to the ip address to be mapped (in the normal nnn.nnn.nnn.nnn
format) and set ethernetaddress to the six byte Ethernet address that this IP address
should be mapped to (such as 08:00:20:05:0b:da).
The optional parameter tim2liv can be set to the length of time, in seconds, to keep
an entry in the ARP table. If no value is specified, a default of 1200 seconds (20
minutes) is used.
range rmarp=on
set arp range=
This is used to remove entries from the ARP table. Set range equal to the range of
table entries to be removed, using the numbers from the Index field when you view
the table using set arp .
You may define up to 16 arp table entries.
ipaddr ether= etaddr [ tim2liv= time]
range rmarp=on
