Igmp Status - Intellinet 560900 User Manual

 Hello Time: Interval (in seconds) at which the root device transmits a configuration
message.
 Max Age: The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. All device ports (except for
designated ports) should receive configuration messages at regular intervals. Any port that
ages out STA information (provided in the last configuration message) becomes the
designated port for the attached LAN. If it is a root port, a new root port is selected from
among the device ports attached to the network.
 Fwd Delay: The maximum time (in seconds) the root device will wait before changing states
(i.e., discarding to learning to forwarding). This delay is required because every device
must receive information about topology changes before it starts to forward frames. In
addition, each port needs time to listen for conflicting information that would make it return
to a discarding state; otherwise, temporary data loops might result.
 Topology: Indicates if Spanning Tree topology is steady or undergoing reconfiguration.
(The time required for reconfiguration is extremely short, so no values other that "steady"
state are likely to be seen in this field.)
 Root ID: The priority and MAC address of the device in the Spanning Tree that this switch
has accepted as the root device, and the port connected to the root device.
RSTP Port Status
 Port/Group: The number of a port or the ID of a static trunk.
 Path Cost: The cost for a packet to travel from this port to the root in the current Spanning
Tree configuration. The slower the media, the higher the cost.
 Edge Port: Shows if this port is functioning as an edge port, either through manual selection
(see the RSTP Port Configuration table) or auto-detection. Note that if the switch detects
another bridge connected to this port, the manual setting for Edge Port will be overridden,
and the port will instead function as a point-to-point connection.
 P2P Port: Shows if this port is functioning as a Point-to-Point connection to exactly one
other bridge. The switch can automatically determine if the interface is attached to a
point-to-point link or to shared media. If shared media is detected, the switch will assume
that it is connected to two or more bridges.
 Protocol: Shows the Spanning Tree protocol functioning on this port, either RSTP or STP
(that is, STP-compatible mode).
