The ARP table displays the following fields:
•
IP Interface—The IPv4 Interface of the directly-connected IP subnet where the IP device
resides.
•
IP Address—The IP address of the IP device.
•
MAC Address—The MAC address of the IP device.
•
Status—Whether the entry was manually entered (static) or dynamically learned.
To add a static ARP entry:
1.
Click Add.
2.
Enter the parameters:
•
Interface—An IPv4 interface can be configured on a port, LAG or VLAN. Select the
desired interface from the list of configured IPv4 interfaces on the device.
•
IP Address—Enter the IP address of the local device.
•
MAC Address—Enter the MAC address of the local device.
3.
Click Apply. The ARP entry is saved to the Running Configuration file
IPv6
The Internet Protocol version 6 (IPv6) is a network-layer protocol for packet-switched Internet
works. IPv6 was designed to replace IPv4, the predominantly deployed Internet protocol.
IPv6 introduces greater flexibility in assigning IP addresses because the address size increases
from 32-bit to 128-bit addresses. IPv6 addresses are written as eight groups of four hexadecimal
digits, for example FE80:0000:0000:0000:0000:9C00:876A:130B. The abbreviated form, in
which a group of zeroes can be left out, and replaced with ‘::’ is also acceptable, for example, ::-
FE80::9C00:876A:130B.
IPv6 nodes require an intermediary mapping mechanism to communicate with other IPv6 nodes
over an IPv4-only network. This mechanism, called a tunnel, enables IPv6-only hosts to reach IPv4
services, and enables isolated IPv6 hosts and networks to reach an IPv6 node over the IPv4
infrastructure.
The device detects IPv6 frames by the IPv6 Ethertype.
