Role of this port in Spanning Tree. This may be one of the following:
Designated - The port is designated for (i.e. carries traffic towards the root for) the LAN it is
connected to.
Root - The single port on the bridge, which provides connectivity towards the root bridge.
Backup - The port is attached to a LAN that is serviced by another port on the bridge. It is not
used but is standing by.

Cost
Synopsis: 0 to 4294967295
Cost offered by this port. If the Bridge RSTP Parameters Cost Style is set to STP, 1Gbps ports
will contribute 4, 100 Mbps ports will contribute 19 and 10 Mbps ports contribute a cost of 100. If
the Cost Style is set to RSTP, 1Gbps will contribute 20,000, 100 Mbps ports will contribute a
cost of 200,000 and 10 Mbps ports contribute a cost of 2,000,000. Note that even if the Cost
style is set to RSTP, a port that migrates to STP will have its cost limited to a maximum of
65535.
