a3ComBrCentralMacCtl 1.3.6.1.4.1.43.2.17.2.1.17

This object is used to enable or disable the Boundary Routing Central MAC feature. If this feature is enabled, (ie, if this object has the value centralMac(1)), the Central Node (in a Boundary Routing environment) will use a special internally saved MAC address as its source MAC address on this port. This will allow certain protocols (such as TCP/IP and IPX) running on the Leaf Nodes to switch to another Central Node without losing sessions. Note, in order for this feature to operate properly, it must be enabled on all the Central Nodes attached to the same Leaf Node. Also note, this feature only applies to Central Nodes (in a Boundary Routing environment) and doesn't apply to the Leaf Nodes. Note, when this parameter is enabled/disabled, the port itself must be disabled and then re-enabled for the new value to take effect. This is done by setting the corresponding instance of ifAdminStatus to up(1).
