Configuring IPv4 IMPB IP-MAC Binding Configuration
2.2.2 Binding Entries via DHCP Snooping
Follow these steps to bind entries via DHCP Snooping:
Step 1 configure
Enter global configuration mode.
Step 2 ip dhcp snooping
Globally enable DHCP Snooping.
Step 3 ip dhcp snooping vlan vlan-range
Enable DHCP Snooping on the specified VLAN.
vlan-range: Enter the vlan range in the format of 1-3, 5.
Step 4 interface { fastEthernet port | range fastEthernet port-list | gigabitEthernet port | range
gigabitEthernet port-list | ten-gigabitEthernet port | range ten-gigabitEthernet port-list |
interface port-channel port-channel-id | interface range port-channel port-channel-id-list
}
Enter interface configuration mode.
Step 5 ip dhcp snooping max-entries value
Configure the maximum number of binding entries the port can learn via DHCP snooping.
value: Enter the value of maximum number of entries. The valid values are from 0 to 512.
Step 6 show ip dhcp snooping
Verify global configuration of DHCP Snooping.
Step 7 end
Return to privileged EXEC mode.
Step 8 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to enable DHCP Snooping globally and on VLAN 5, and
set the maximum number of binding entries port 1/0/1 can learn via DHCP snooping as
100:
Switch#configure
Switch(config)#ip dhcp snooping
Switch(config)#ip dhcp snooping vlan 5
Switch(config)#interface gigabitEthernet 1/0/1
Switch(config-if)#ip dhcp snooping max-entries 100
Switch(config-if)#show ip dhcp snooping
Global Status: Enable
