Description: This is the list of port(s) on which the given MAC Address is configured Note that this port list is constructed assuming there are as many ports per slot as given in the object extremeChassisPortsPerSlot. Thus, if extremeChassisPortsPerSlot is 128, then the 129th bit in the port list (reading left to right) indicates port 2:1. Similarly, the 256th bit would indicate port 2:128 while the 257th bit would indicate port 3:1. Note especially that the bit positions in port list do not depend on the actual physical presence or absence of the given ports on the blade or of any blade itself.
