This object is used to enable or disable a shared MAC for SNMP protocol usage. Note that if a shared MAC has insufficient capabilities to run the SNMP stack then an attempt to set the status to active will fail. This object has three values: available, unavailable and snmpMac. The meaning of each of these is:

available: This MAC is currently available to run SNMP on behalf of the management card. unavailable: MAC cannot be selected to carry SNMP on behalf of the management card. The MAC may be in this state for a number of reasons. Examples are insufficient resource on the card, shared MAC already in use for something other than SNMP. snmpMac: This MAC is currently being used as the physical interface for management card SNMP traffic.

To select a MAC write snmpMac to this object. If the MAC is suitable and available then the current snmpMac will become unavailable and the selected MAC will become available.
