Commands for IP process

1. arp

Syntax:

arp add <i/f> <IP address> <MAC address> arp delete <i/f> <IP address>

arp flush arp [list]

arp help [all<cmd>]

Description:

Allows display and manipulation of the ARP table: the list of IP addresses and corresponding MAC addresses obtained by ARP on Ethernet-like interfaces. Normally there is no need to add entries to the table with “arp add”, since they should be discovered by the ARP protocol. Displaying the table with “arp list” (or just “arp”) is sometimes useful, and deleting an entry with “arp delete”, or the whole table with “arp flush”, can sometimes speed up recovery from temporary problems if something unusual has happened. Entries added with “arp add” do not time out like those discovered by use of the ARP protocol, but they are deleted by “arp flush” and will not survive a restart (they are not saved by configuration saving). Note that the ARP table is used only for destinations on directly connected Ethernet-like networks, not for those reached through routers (although the ARP table may be used to discover the MAC address of the router).

Example:

DSL> ip arp add ether 192.168.50.1 8:0:20:19:9A:D9

DSL> ip arp

arp add flane 192.168.2.63 00:20:2b:e0:03:87 # 8m58s arp add flane 192.168.2.109 00:20:2b:03:08:b1 # 2m24s arp add ether 192.168.50.1 08:00:20:19:9a:d9 # forever arp add ether 192.168.50.57 00:20:af:2e:fa:3c # 3m25s DSL> ip arp delete flane 192.168.2.109

DSL> ip arp list

arp add flane 192.168.2.63 00:20:2b:e0:03:87 # 8m46s arp add ether 192.168.50.1 08:00:20:19:9a:d9 # forever arp add ether 192.168.50.57 00:20:af:2e:fa:3c # 3m13s

DSL> ip arp flush

DSL> ip arp

#flane ARP table is empty

#ether ARP table is empty DSL> ip arp
