Configuring IPv4
SUMMARY STEPS
1. configure terminal
2. interface ethernet number
3. no switchport
4. ip arp ipaddr mac_addr
5. (Optional) copy running-config startup-config
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.
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
Example:
switch(config-if)# ip arp 192.2.1.1
0019.076c.1a78
Associates an IP address with a MAC address as a
static entry.
Step 5
copy running-config startup-config
Example:
switch(config-if)# copy running-config
startup-config
(Optional) Saves this configuration change.
