The nodes in a VC are represented as the cards of a chassis. Each card is assigned a slot number. Using the slot number, services are provisioned on the card using the format slot-number/mda-number/port-number:sap-id, where the slot-number is configured for every node/card, the mda-number is always set to 1 for all 7210 SAS-Sx/S 1/10GE platforms supporting VC, and the port-number corresponds to the front-panel Ethernet port number and ranges from 1 to 28 or from 1 to 52 for 7210 SAS-Sx/S 1/10GE platforms.
