Port Port or trunked port identifier.
Priority Defines the priority used for this port
in the Spanning Tree Algorithm.
If the path costs for all ports on a Switch are the same, the port with
the highest priority (i.e., lowest value) will be configured as an active
link in the Spanning Tree. This makes a port with higher priority less
likely to be blocked if the Spanning Tree Algorithm is detecting
network loops. When more than one port is assigned the highest
priority, the port with lowest numeric identifier will be enabled. The
range is from 0 to 240, in steps of 16; and the default is: 128.
Path Cost The Internal Path Cost setting allows you to specify the relative cost
of sending spanning tree traffic through the interface to adjacent
bridges within a spanning tree region.
Designated Root
Bridge
Displays the root bridge for the CST. It is comprised using the bridge
priority and the base MAC address of the bridge.
External Root Cost External root cost is the cost to the CIST root.
Regional Root
Bridge
This is the bridge identifier of the CST regional root. It is made up
using the bridge priority and the base MAC address of the bridge.
Designated Bridge This is the bridge identifier of the bridge of the designated port. It is
made up using the bridge priority and the base MAC address of the
bridge.
Edge Port
Conf/Oper
Displays the edge port state.
P2P MAC
Conf/Oper
Modify link type to point-to-point or a shared LAN.
Port Role Each MST bridge port that is enabled is assigned a port role within
each spanning tree. The port role will be one of the following values:
Root Port, Designated Port, Alternate Port, Backup Port, Master
Port, or Disabled.
Port State The forwarding state of this port. The state parameters are:
Discarding, Learning, Forwarding, or Disabled.
Migration Start When STP migrate between different protocol, basically device will
keep (or lock) the using protocol for a while to avoid flapping or
toggling.
