Allied Telesis AT-WR4500 manual Address Resolution Protocol, Submenu level /ip arp

88	AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers
	RouterOS v3 Configuration and User Guide

Property Description

actual-interface (read-only: name) - only applicable to logical interfaces like bridges or tunnels. Holds the name of the actual hardware interface the logical one is bound to.

address (IP address) - IP address

broadcast (IP address; default: 255.255.255.255) - broadcasting IP address, calculated by default from an IP address and a network mask

disabled (yes no; default: no) - specifies whether the address is disabled or not interface (name) - interface name the IP address is assigned to

netmask (IP address; default: 0.0.0.0) - specifies network address part of an IP address

network (IP address; default: 0.0.0.0) - IP address for the network. For point-to-point links it should be the address of the remote end

￿

You cannot have two different IP addresses from the same network assigned to the router. Exempli gratia, the combination of IP address 10.0.0.1/24 on the ether1 interface and IP address 10.0.0.132/24 on the ether2 interface is invalid (unless both interfaces are bridged together), because both addresses belong to the same network 10.0.0.0/24. Use addresses from different networks on different interfaces.

Example

[admin@AT-WR4562] ip address> add address=10.10.10.1/24 interface=ether2

[admin@AT-WR4562] ip address> print
Flags: X - disabled, I - invalid, D - dynamic
#	ADDRESS	NETWORK	BROADCAST	INTERFACE
0	2.2.2.1/24	2.2.2.0	2.2.2.255	ether2
1	10.5.7.244/24	10.5.7.0	10.5.7.255	ether1
2	10.10.10.1/24	10.10.10.0	10.10.10.255	ether2

[admin@AT-WR4562] ip address>

5.1.3 Address Resolution Protocol

Submenu level: /ip arp

Description

Even though IP packets are addressed using IP addresses, hardware addresses must be used to actually transport data from one host to another. Address Resolution Protocol is used to map OSI level 3 IP addresses to OSI level 2 MAC addresses. A router has a table of currently used ARP entries. Normally the table is built dynamically, but to increase network security, it can be built statically by means of adding static entries.

Property Description

address (IP address) - IP address to be mapped

interface (name) - interface name the IP address is assigned to

mac-address (MAC address; default: 00:00:00:00:00:00) - MAC address to be mapped to

￿

Maximum number of ARP entries is 8192.
