Displaying ARP Cache

You can display the ARP cache on Gigabit Ethernet interfaces.
Note Use the physical interface, not the subinterface, for all ARP cache commands.
Use the show ips arp interface gigabitethernet command to display the ARP cache on the Gigabit
Ethernet interfaces. This command takes the Ethernet interface as a parameter and returns the ARP cache
for that interface. See
Example 7-3
switch# show ips arp interface gigabitethernet 7/1

Clearing ARP Cache

The ARP cache can be cleared in two ways: clearing just one entry or clearing all entries in the ARP
cache.
Use the clear ips arp command to clear the ARP cache. See
Example 7-4
switch# clear ips arp address 10.2.2.2 interface gigabitethernet 8/7
arp clear successful
Example 7-5
switch# clear ips arp interface gigabitethernet 8/7
arp clear successful

Displaying IPv4 Statistics

Use the show ips stats ip interface gigabitethernet to display and verify IP v4 statistics. This command
takes the main Ethernet interface as a parameter and returns the IPv4 statistics for that interface. See
Example
Use the physical interface, not the subinterface, to displayIPv4 statistics.
