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 age 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 waits before changing states (i.e.,
discarding to learning to forwarding). This delay is required because every device should
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 occur.
➤
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.
IGMP Status
IGMP Status
IGMP Status shows the IGMP Snooping statistics for the whole switch.
➤
VLAN ID: VLAN ID number.
➤
Querier: Show whether Querying is enabled.
➤
Queries transmitted: Show the number of transmitted Query packets.
➤
Queries received: Show the number of received Query packets.
➤
v1 Reports: Show the number of received v1 Report packets.
➤
v2 Reports: Show the number of received v2 Report packets.
➤
v3 Reports: Show the number of received v2 Report packets.
➤
v3 Leave: Show the number of v3 leave packets received.
