MAC pools control IP address allocation based on a client’s MAC address. A MAC pool is a group containing one or more MAC addresses. After creating a MAC pool and adding MAC addresses to it, you can set deployment options to control which clients are allowed to receive IP addresses from specific DHCP pools.
By default, all MAC addresses are allowed to obtain an IP address from a DHCP server. You can change this behavior with three DHCP service deployment options: Allow MAC Pools, Deny MAC Pools, and Deny Unknown MAC Addresses. These deployment options can be set at the configuration, IP block, IP network, or DHCP range levels.
To create a MAC pool:
- From the configuration drop-down menu, select a configuration.
- Select the Devices tab. Tabs remember the page on which you last worked, so select the tab again to ensure you're on the Configuration Information page.
- Click the MAC tab.
- Under Pools, click New.
- In the Name field, type a name for the MAC pool.
- Under Change Control, add comments, if required.
- Click Add or click Add Next.
