NETGEAR 24-Port Gigabit Smart Managed Pro Switch with PoE+ and 2 SFP Ports Model GS724TPv2 The following table describes the nonconfigurable information on the page. Table 28. MST port status information Field Description Auto-calculated Port Path Cost Displays whether the path cost is automatically calculated (Enabled) or not (Disabled). Path cost is calculated based on the link speed of the port if the configured value for Port Path Cost is zero. Port ID The port identifier for the specified port within the selected MST instance. It is made up from the port priority and the interface number of the port. Port Up Time Since Counters Time since the counters were last cleared, displayed in days, hours, minutes, Last Cleared and seconds. Port Mode Spanning Tree Protocol administrative mode associated with the port or port channel. Possible values are Enable or Disable. Port Forwarding State Indicates the current STP state of a port. If enabled, the port state determines what forwarding action is taken on traffic. Possible port states are as follows: • Disabled. STP is currently disabled on the port. The port forwards traffic while learning MAC addresses. • Blocking. The port is currently blocked and cannot be used to forward traffic or learn MAC addresses. • Listening. The port is currently in the listening mode. The port cannot forward traffic nor can it learn MAC addresses. • Learning. The port is currently in the learning mode. The port cannot forward traffic. However, it can learn new MAC addresses. • Forwarding. The port is currently in the forwarding mode. The port can forward traffic and learn new MAC addresses Port Role Each MST bridge port that is enabled is assigned a port role for each spanning tree. The port role is one of the following: Root Port, Designated Port, Alternate Port, Backup Port, Master Port, or Disabled Port. Designated Root Root bridge for the selected MST instance. It is made up using the bridge priority and the base MAC address of the bridge. Designated Cost Displays cost of the port participating in the STP topology. Ports with a lower cost are less likely to be blocked if STP detects loops. Designated Bridge Bridge identifier of the bridge with the designated port. It is made up using the bridge priority and the base MAC address of the bridge. Designated Port Port identifier on the designated bridge that offers the lowest cost to the LAN. It is made up from the port priority and the interface number of the port. Configure Switching 129

The following table describes the nonconfigurable information on the page.
Table 28.
MST port status information
Field
Description
Auto-calculated Port Path
Cost
Displays whether the path cost is automatically calculated (Enabled) or not
(Disabled). Path cost is calculated based on the link speed of the port if the
configured value for Port Path Cost is zero.
Port ID
The port identifier for the specified port within the selected MST instance. It is
made up from the port priority and the interface number of the port.
Port Up Time Since Counters
Last Cleared
Time since the counters were last cleared, displayed in days, hours, minutes,
and seconds.
Port Mode
Spanning Tree Protocol administrative mode associated with the port or port
channel. Possible values are Enable or Disable.
Port Forwarding State
Indicates the current STP state of a port. If enabled, the port state determines
what forwarding action is taken on traffic. Possible port states are as follows:
•
Disabled
. STP is currently disabled on the port. The port forwards traffic
while learning MAC addresses.
•
Blocking
. The port is currently blocked and cannot be used to forward
traffic or learn MAC addresses.
•
Listening
. The port is currently in the listening mode. The port cannot
forward traffic nor can it learn MAC addresses.
•
Learning
. The port is currently in the learning mode. The port cannot
forward traffic. However, it can learn new MAC addresses.
•
Forwarding
. The port is currently in the forwarding mode. The port can
forward traffic and learn new MAC addresses
Port Role
Each MST bridge port that is enabled is assigned a port role for each spanning
tree. The port role is one of the following: Root Port, Designated Port, Alternate
Port, Backup Port, Master Port, or Disabled Port.
Designated Root
Root bridge for the selected MST instance. It is made up using the bridge priority
and the base MAC address of the bridge.
Designated Cost
Displays cost of the port participating in the STP topology. Ports with a lower
cost are less likely to be blocked if STP detects loops.
Designated Bridge
Bridge identifier of the bridge with the designated port. It is made up using the
bridge priority and the base MAC address of the bridge.
Designated Port
Port identifier on the designated bridge that offers the lowest cost to the LAN. It
is made up from the port priority and the interface number of the port.
