.1.3.6.1.4.1.9.9.87.1.4.1.1.6
Object
This object reflects an internal state of the port
with regard to its ability to forward frames.
A port sometimes stops forwarding frames when it
is blocked by the Spanning Tree Protocol, or
while it is undergoing temporary load balancing
as part of the port grouping usage.
This object is true(1) if the port is allowed to
forward frames. It is false(2) otherwise.
Setting this object to true(1) will fail,
if the port is in the middle of being blocked by the Spanning Tree
Protocol, or while it is undergoing temporary load balancing
as part of the port grouping usage.
This object is only supported for static VLAN access ports.
