Chapter 1 Configuring IP Unicast Routing
Configuring IP Addressing
Beginning in privileged EXEC mode, follow these steps to specify the ARP encapsulation type:
To disable an encapsulation type, use the no arp arpa or no arp snap interface configuration command.
Enable Proxy ARP
By default, the switch uses proxy ARP to help hosts learn MAC addresses of hosts on other networks or
subnets.
Beginning in privileged EXEC mode, follow these steps to enable proxy ARP if it has been disabled:
To disable proxy ARP on the interface, use the no ip proxy-arp interface configuration command.
Routing Assistance When IP Routing is Disabled
These mechanisms allow the switch to learn about routes to other networks when it does not have IP
routing enabled:
• Proxy ARP, page 1-13
• Default Gateway, page 1-13
• ICMP Router Discovery Protocol (IRDP), page 1-13
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Enter interface configuration mode, and specify the Layer 3
interface to configure.
Step 3
arp {arpa | snap} Specify the ARP encapsulation method:
• arpa—Address Resolution Protocol
• snap—Subnetwork Address Protocol
Step 4
end Return to privileged EXEC mode.
Step 5
show interfaces [interface-id] Verify ARP encapsulation configuration on all interfaces or
the specified interface.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Enter interface configuration mode, and specify the Layer 3
interface to configure.
Step 3
ip proxy-arp Enable proxy ARP on the interface.
Step 4
end Return to privileged EXEC mode.
Step 5
show ip interface [interface-id] Verify the configuration on the interface or all interfaces.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
