• RSTP—Rapid Spanning Tree Protocol (IEEE 802.1w); RSTP is the default.
Priority—Specifies the bridge priority value. When switches or bridges are running STP, each is
assigned a priority. After exchanging BPDUs, the device with the lowest priority value becomes
the Root Bridge. The default value is 32768. The port priority value is provided in increments of
4096. For example, 4096, 8192, 12288, etc. The range is 0 to 65535.
Hello Time—Specifies the number of seconds a root bridge waits between configuration
messages. The default is 2 seconds. The range is 1 to 10 seconds.
Maximum 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 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. (References to "ports" in this section mean "interfaces, " which
includes both ports and LAGs.) The default max age is 20 seconds. The range is 6 to 40 seconds.
Forward Delay—The maximum time (in seconds) this 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. The default is 15 seconds. The
range is 4 to 30 seconds.
Path Cost Method—The path cost is used to determine the best path between devices. The
path cost method is used to determine the range of values that can be assigned to each
interface
• Long—Specifies 32-bit based values that range from 1-200,000,000. (This is the default.
• Short—Specifies 16-bit based values that range from 1-65535.
Transmission Limit—The maximum transmission rate for BPDUs. This limit is specified by
setting the minimum interval between the transmission of consecutive protocol messages.
