Configuring Interfaces and TCP/IP Features
5-15
A.B.C.D is the IP address of the ARP entry, specified in dotted-decimal
notation.
mac-address is a 48-bit hardware address of the ARP entry.
type is the encapsulation type.
alias specifies that the software respond to ARP as if it owns the specified
address, if proxy arp is enabled.
2. To set the ARP cache timeout for a specific interface, use the arp timeout
command in Interface Configuration mode, as shown below:
MOT(config)#arp timeout <number>
where:
number is ARP cache timeout value, expressed in minutes; valid entries are 1
to 6000; default is 60.
Use the no arp timeout command to restore the default.
Reverse ARP
Reverse ARP, defined in RFC 903, works like ARP, except that the RARP request
packet requests an Internet address instead of a hardware address. The BSR acts as an
RARP server. To enable RARP, use the ip rarp-server command in Interface
Configuration mode, as shown below. Set the IP address to one of the interface
addresses.
MOT(config-if)#ip rarp-server <A.B.C.D>
where:
A.B.C.D is the source protocol IP address in replies.
