 Configuring free ARP function
The switch can know whether the IP addresses of other devices collide with its IP address by sending free
ARP message. The source IP address and the destination IP address contained by free ARP message are
both the local address of the switch. The source MAC address of the message is the local MAC address.
The switch processes free ARP message by default. When the switch receives free ARP message from a
device and finds that the IP address contained in the message collide with its own IP address, it will return an
ARP answer to the device, informing the device that the IP addresses collide with each other. At the same
time, the switch will inform users by logs that IP addresses collide.
The switch’s function to send free ARP message is disabled by default. Run the following commands to
configure the free ARP function on the port of the switch:
Run… To…
arp send-gratuitous
Start up free ARP message
transmission on the interface.
arp send-gratuitous intervalvalue
Set the interval for sending free ARP
message on the interface.
The default value is 120 seconds.
2. Mapping host name to IP addres
Any IP address can correspond to a host name. The system stores a hostname-to-address mapping cache
that you can telnet or ping.
Run the following command in global configuration mode to specify a mapping between host name and IP
address:
Run… To…
ip hostname address
Statically map the host name to the IP
address.
