The following question was asked by Ben Kaduk during IESG review of the
following document: 




     grouping l2-node-attributes {


         leaf sys-mac-address {

           type yang:mac-address;


             "System MAC address.";



If there are more than 1 system mac address in a switch, how would this
model handle it. 


My understanding is that most switches have 1 system mac address for network
management.  Therefore, the L2 topology model supports one. 


Question for Yang Doctors: 


1) Is this the normal assumption for yang models? 

2) If not, what is the normal assumption on system mac addresses? 


3) Am I correct that switches with more than 1 system MAC will augment their
basic yang model with the second system MAC Address. 


Thank you, Susan Hares
