The value of TRUE(1) means the stp status of the port is
enabled, otherwise it is disabled.

The administrative edged port status of this port.
A value of forceTrue(0) indicates that this port should
always be treated as edged port.
A value of forceFalse(1) indicates that this port should
not be treated a…

Ports with this object set as false(2) do not participate in
any STP computation; they are always in Forwarding state, do not
send any BPDU and all BPDUs received on these Ports will be discarded.
Such ports are used…

to no will up the port.

A unique value identifies an instance. The entry of this
table with index 0 always represents the CIST instance.

Each octet within this value specifies a set of eight
vlans, with the first octet specifying vlan 1 through 8,
the second octet specifying vlan 9 through 16, etc.
Within each octet, the most significant bit represent…

from 0 to 4095. The instances of this table entry with
rcMstpXstInstanceEditId of zero is automatically created
by the device and can not modified.
