As shown in
the arp-ping mac command on Switch A to check whether the MAC address 0013-46E7-2EF5
is in use.
Figure 2-2 Implementation procedure of ARP-Ping MAC
The following describes how to implement ARP-Ping MAC on Switch A:
Run the arp-ping mac 0013-46E7-2EF5 10.1.1.0 or arp-ping mac 0013-46E7-2EF5
gigabitethernet 1/0/0 command on Switch A. After receiving the ICMP Reply packets replied
by all the hosts on the network, Switch A displays the IP address of the host with the MAC
address 0013-46E7-2EF5.
Through the command output, you can obtain the IP address corresponding to the MAC address.

2.3 Configuring Static ARP

Static ARP indicates that there is a fixed mapping between an IP address and a MAC address.
Static ARP needs to be configured by an administrator.
Issue 01 (2012-03-15)
After setting the specified MAC address through the command line, you can send broadcast
ICMP Echo Request packets and start the timeout timer.
After receiving an ICMP Echo Request packet, each device or host on the LAN replies with
an ICMP Echo Reply packet.
After receiving the ICMP Echo Reply packet, the source device compares the source MAC
address contained in the Echo Reply packet with the MAC address input in the command
line. If they are consistent, the IP address of the Echo Reply packet is displayed. Then the
source device prompts you that the MAC address is in use and disables the timeout timer.
The operation finishes.
If the timeout timer of the ICMP Echo Reply packets times out, it means that the MAC
address is not in use.
NOTE
If the system denies the request for replying with the network segment address, the sender cannot receive
the ICMP Echo Reply packet.
Figure 2-2, Switch A and Gigabitethernet A are directly connected. You can run
Host A
0013-46E7-2EF5
GE1/0/0
10.1.1.1/24
Gigabitethernet A
NOTE
The arp-ping mac command is applicable to the outgoing interface in one of the following types: the
Ethernet interface, Gigabit Ethernet interface, Eth-Trunk interface, and VLANIF interface.
