Step 3
show ip source binding
Verify the binding entry.
Step 4
end
Return to privileged EXEC mode.
Step 5
copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to bind an entry with the hostname host1, IP address
192.168.0.55, MAC address AA-BB-CC-DD-EE-FF, VLAN ID 10, port number 1/0/5, and
enable this entry for the ARP detection feature.
Switch#configure
Switch(config)#ip source binding

2.2.2 Viewing Binding Entries
On privileged EXEC mode or any other configuration mode, you can use the following
command to view binding entries:
show ip source binding
View the information of binding entries, including the host name, IP address, MAC address, VLAN ID, port
number, protect type and collision status.
There are two types of collision status: Warning and Critical.
Warning
: The collision entries have the same IP address and MAC address, and all the collision entries are
valid. This kind of collision may be caused by the MSTP function.
Critical
: The collision entries have the same IP address but different MAC addresses. For the collision
entries learned from the same source, only the newly added entry will be valid. For the collision entries
learned different sources, only the entry with the highest priority will be valid. The priority of different entry
types, from high to low, is Manually, ARP Scanning and DHCP Snooping.
