In global configure directory, input arp, prompt is as below:
(00)dynamic
(01)A.B.C.D
Please Input the code of command to be excute(0-1): 1
Input 1，select A.B.C.D option，prompt is as below：
Please input a IP Address:
Input ip-address，prompt is as below：
(00) H:H:H:H:H:H
Please Input the code of command to be excute(0-0): 0
Input 0，prompt is as below：
Please input a Hardware Address:
Input hardware-address，prompt is as below：
(00)alias
(01)<cr>
Please Input the code of command to be excute(0-1):
Input 1，then it will map an IP address to a medium address globally in ARP buffer;
Input 0，select alias option，then you specify the router to reply to ARP request of specified IP address
with its own MAC address.
Use the following command to configure timeout of the ARP item in ARP buffer:
arp timeout seconds
Select 0 option in the prompt, then prompt is as below:
(00)timeout
Please Input the code of command to be excute(0-0): 0
Input 0，select timeout option，
(00)<0-4294967>
Please Input the code of command to be excute(0-0): 0
Input 0，prompt is as below：
Please input a digital number:Please input a string:
Configure timeout value.
To display the ARP timeout value being used on a particular interface, use the show interfaces
command. Use the show arp command to examine the contents of the ARP cache. To remove all
nonstatic entries from the ARP cache, use the privileged command clear arp-cache.
Enable Proxy ARP
The router uses proxy ARP, as defined in RFC 1027, to help hosts with no knowledge of routing
determine the media addresses of hosts on other networks or subnets. For example, if the router
receives an ARP request for a host that is not on the same interface as the ARP request sender, and if
the router has all of its routes to that host through other interfaces, then it generates a proxy ARP reply
packet giving its own local data link address. The host that sent the ARP request then sends its packets
to the router, which forwards them to the intended host. Proxy ARP is enabled by default.
To enable proxy ARP, select ip option in configuring prompt, then select option proxy-arp:
ip proxy-arp
2. Map a Host Name to an IP Addresse
Each unique IP address can have a host name associated with it. The router maintains a cache of host
name-to-address mappings for use by the command telnet, ping, etc.
