WDS and STP
‐Range: 0‐65535
‐Default: 32768
–Bridge Max Age is 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 STP 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. Range: 6‐40 seconds
‐Default: 20
‐Minimum: The higher of 6 or [2 x (Hello Time + 1)].
‐Maximum: The lower of 40 or [2 x (Forward Delay ‐ 1)]
–Bridge Hello Time is the interval (in seconds) at which the root device transmits a configuration message. Range: 1‐10 seconds
‐Default: 2
‐Minimum: 1
‐Maximum: The lower of 10 or [(Max. Message Age / 2) ‐1]
–Bridge Forward Delay is the maximum time (in seconds) this device waits before changing states (for example, 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. Range: 4‐30 seconds
‐Default: 15
‐Minimum: The higher of 4 or [(Max. Message Age / 2) + 1]
‐Maximum: 30
–Link Path Cost is used by the STP to determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. Path cost takes precedence over port priority.
‐Range: 1‐65535
‐Default: Ethernet interface: 19; Wireless interface: 40
–Link Port Priority defines the priority used for this port in the Spanning Tree Protocol. If the path cost for all ports on a switch are the same, the port with the highest priority (for example, 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 Protocol is detecting network loops. Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled.
‐Default: 128
‐Range: 0‐255, in steps of 16
