Configuring IP Unicast Routing
Configuring IP Addressing
DETAILED STEPS
Command
1. configure terminal
2. arp ip-address hardware-address type
3. arp ip-address hardware-address type
[alias]
4. interface interface-id
5. no shutdown
6. arp timeout seconds
7. end
8. show interfaces [interface-id]
9. show arp
or
show ip arp
10. copy running-config startup-config
To remove an entry from the ARP cache, use the no arp ip-address hardware-address type global configuration
command. To remove all nonstatic entries from the ARP cache, use the clear arp-cache privileged EXEC command.
EXAMPLE
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# arp 10.0.0.0 aabb.cc03.8200 arpa
Switch(config)# end
Setting ARP Encapsulation
By default, Ethernet ARP encapsulation (represented by the arpa keyword) is enabled on an IP interface. You can change
the encapsulation methods to SNAP if required by your network.
BEFORE YOU BEGIN
The encapsulation type specified in this procedure should match the encapsulation type specified in the
ARP Cache, page 804.
Purpose
Enter global configuration mode.
Globally associate an IP address with a MAC (hardware)
address in the ARP cache, and specify encapsulation
type as one of these:

arpa—ARP encapsulation for Ethernet interfaces

snap—Subnetwork Address Protocol encapsulation
for Token Ring and FDDI interfaces

sap—HP's ARP type
(Optional) Specify that the switch respond to ARP
requests as if it were the owner of the specified IP
address.
Enter interface configuration mode, and specify the
interface to configure.
Enable the interface if necessary. By default, UNIs and
ENIs are disabled and NNIs are enabled.
(Optional) Set the length of time an ARP cache entry will
stay in the cache. The default is 14400 seconds (4
hours). The range is 0 to 2147483 seconds.
Return to privileged EXEC mode.
Verify the type of ARP and the timeout value used on all
interfaces or a specific interface.
View the contents of the ARP cache.
(Optional) Save your entries in the configuration file.
End with CNTL/Z.
