A MAC pool is a collection of network identities or MAC addresses that are unique in their layer 2 environment and are available to be assigned to vNICs on a server. MAC pools created in Cisco UCS Central can be shared between Cisco UCS domains. If you use MAC pools in service profiles, you do not have to manually configure the MAC addresses to be used by the server associated with the service profile.
In a system that implements multi-tenancy, you can use the organizational hierarchy to ensure that MAC pools can only be used by specific applications or business services. Cisco UCS Central uses the name resolution policy to assign MAC addresses from the pool.
To assign a MAC address to a server, you must include the MAC pool in a vNIC policy. The vNIC policy is then included in the service profile assigned to that server.
You can specify your own MAC addresses or use a group of MAC addresses provided by Cisco.

After creating a MAC pool you can edit it by selecting the Edit icon on the overall summary page of the selected MAC pool. To select a MAC pool, go to All Pools page and select the MAC pool that you want to edit. The page redirects you to the overall summary page of the selected MAC pool.

Deleting a Pool
If you delete a pool, Cisco UCS Central does not reallocate any addresses from that pool that have been assigned to vNICs or vHBAs in Cisco UCS Manager. All assigned addresses from a deleted pool remain with the vNIC or vHBA to which they are assigned until one of the following occurs:
The associated service profiles are deleted.
The vNIC or vHBA to which the address is assigned is deleted.
The vNIC or vHBA is assigned to a different pool.
Click the Browse Tables icon and choose Pools.
In the Pool Name column, locate the pool that you want to delete.
You can search for the pool in one of the following ways:
