Syntax

[no]ip source-binding <mac-address> vlan

<vlan-id><ip-address>interface <port-number>

mac-address

Specifies a MAC address to bind with a VLAN and IP address on the specified

port in the DHCP binding database.

vlan-id

Specifies a VLAN ID number to bind with the specified MAC and IP addresses

on the specified port in the DHCP binding database.

ip-address

Specifies an IP address to bind with a VLAN and MAC address on the specified

port in the DHCP binding database.

<port-number>

Specifies the port number on which the IP-to- MAC address and VLAN binding

is configured in the DHCP binding database.

An example of the ip source-binding command is shown here:

HP Switch(config)# ip source-binding 0030c1-7f49c0

interface vlan 100 10.10.20.1 interface A4

NOTE: Note that the ip source-binding command is the same command used by the

Dynamic IP Lockdown feature to configure static bindings. The Dynamic ARP Protection and Dynamic

IP Lockdown features share a common list of source IP-to-MAC bindings.

Displaying the static configuration of IP-to-MAC bindings

To display the static configurations of IP-to-MAC bindings stored in the DHCP lease database, enter

the show ip source-lockdown bindings command.

Syntax

show ip source-lockdown bindings [port-number]

port-number

(Optional) Specifies the port number on which source IP-to-MAC address and

VLAN bindings are configured in the DHCP lease database.

An example of the show ip source-lockdown bindings command output

is shown in Figure 11-6.
