NETGEAR GS752TP, GS728TPP manual 212

GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches

•Port Role. Each MST bridge port that is enabled is assigned a port role for each spanning tree. The port role can be one of the following values: Root Port, Designated Port, Alternate Port, Backup Port, Master Port, or Disabled Port.

•STP Mode. The Spanning Tree Protocol (STP) administrative mode for the port or LAG. The possible values for this field are:

•Enable. Spanning Tree Protocol is enabled for this port.

•Disable. Spanning Tree Protocol is disabled for this port.

•STP State. The port current state spanning tree state. This state controls what action a port takes on receipt of a frame. If the bridge detects a malfunctioning port, it places that port into the broken state. The other five states are defined in IEEE 802.1D:

•Disabled

•Blocking

•Listening

•Learning

•Forwarding

•Broken

•Admin Mode. The port control administration state:

•Enable. The port can participate in the network (default).

•Disable. The port is administratively down and does not participate in the network.

•LACP Mode. The Link Aggregation Control Protocol administration state:

•Enable. The port is allowed to participate in a port channel (LAG), which is the default mode.

•Disable. The port cannot participate in a port channel (LAG).

•Physical Mode. The port speed and duplex mode. In autonegotiation mode, the duplex mode and speed are set from the autonegotiation process.

•Physical Status. The port speed and duplex mode status.

•Link Status. Indicates whether the port link is up or down.

•Link Trap. Determines whether to send a trap when link status changes. The factory default is Enable.

•Enable. The system sends a trap when the link status changes.

•Disable. The system does not send a trap when the link status changes.

•Octets Received. The total number of octets of data (including those in bad packets) received on the network (excluding framing bits, but including FCS octets). This object can be used as a reasonable estimate of ethernet utilization.

•Packets Received 64 Octets. The total number of packets (including bad packets) received that were 64 octets in length (excluding framing bits but including FCS octets).
