Parameter
static: Specifies a static address.
ip_address: Enter the client’s static IP address.
mac_address: Enter the client’s MAC address.
Description
■ Use the dhcp-security command to assign a client’s static IP address to a
particular MAC address. In this way you can build a table of static IP addresses
and corresponding MAC addresses. The table applies globally, that is, it is not
associated with a specific DHCP server group.
■ Use the undo dhcp-security command to remove an entry from the static
table.
You can use the display dhcp-security command to view the static IP address
information.
Related command: display dhcp-security, dhcp-server.
Example
To assign the IP address 1.1.1.1 to the MAC address 0005-5D02-F2B3, and add
this information to the static address table, enter the following:
[SW7700]dhcp-security static 1.1.1.1 0005-5D02-F2B3
