Configuring IPv4
DETAILED STEPS
This example shows how to configure a static ARP entry:
switch# configure terminal
switch(config)# interface ethernet 2/3
switch(config-if)# no switchport
switch(config-if)# ip arp 192.2.1.1 0019.076c.1a78
switch(config-if)# copy running-config startup-config
Configuring Proxy ARP
You can configure Proxy ARP on the switch to determine the media addresses of hosts on other networks
or subnets.
SUMMARY STEPS
1. configure terminal
2. interface ethernet number
3. no switchport
4. ip proxy-arp
5. (Optional) copy running-config startup-config
Command Purpose
Step 1
configure terminal
Example:
switch# configure terminal
switch(config)#
Enters configuration mode.
Step 2
interface ethernet number
Example:
switch(config)# interface ethernet 2/3
switch(config-if)#
Enters interface configuration mode.
Step 3
no switchport
Example:
switch(config-if)# no switchport
Configures the interface as a Layer 3 routed interface.
Step 4
ip arp ipaddr mac_addr
