Cisco UCS manager – How to Create the MAC POOL ?

Cisco UCS blades are not encoded with MAC address. So we need to create the MAC addresses, that are unique in their Layer 2 environment and are available to be assigned to vNICs on a server.  To assign a MAC address to a blade , you have to 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.  For each group of servers (i.e. “ESXi_Servers” etc.), create two MAC pools. One that will go out of the “A” fabric another that will go out the “B” fabric.

 

Create MAC pool for Fabric – A  (For Sub-organization – ESXi-Pool)

 

1. Login to the UCS Manager .

2. Navigate to LAN  tab – > Pools – > root -> “Sub-organization” – > Click the “Sub-organization” which we have created.

3. Right click the “MAC Pools” and click on “Create MAC pool” .

From there,  give each pool a name and MAC address range that will allow you to easily identify the type of server it is (e.g. “11” for production ESXi host) and the fabric it should be going out (e.g. “A” or “B”).
