IEEE8021-AS-MIB Table View

A table of gPTP port related variables in a time-aware 
Bridge or for a time-aware end station.  A value of 1 is used in 
a bridge or an end station that does not have multiple 
components.
          
For a given media port of a Bridge or an end station, there may 
be one or more gPTP port, and depends whether a media port 
supports point to point link (e.g. IEEE 802.3 Ethernet) or point 
to multi-point (e.g. CSN, IEEE 802.3 EPON, etc) links on the 
media port.
