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
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.
