 Hello Time: Interval (in seconds) at which the root device transmits a configuration
message (BPDU frame). Number between 1 and 10 (default is 2).
 Max Age: The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. This also means the maximum
lifetime for a BPDU frame. Number between 6 and 40 (default is 20).
 Forward Delay: The maximum time (in seconds) the root device will wait before changing
states (i.e., discarding to learning to forwarding). Number between 4 and 30 (default is 15).
 Force Version: Set and show the RSTP protocol to use. Normal - use RSTP; Compatible -
compatible with STP.
RSTP Port Configuration
 Port: The port ID. Aggregations mean any configured trunk group.
 Protocol Enabled: Select to enable/disable the RSTP protocol for the port.
 Edge: Expect the port to be an edge port (linking to an end station) or a link to another STP
device.
 Path Cost: This parameter 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. Set the RSTP path cost on the port. Number
between 0 and 200000000. The default value is "auto," meaning the system will
automatically generate path cost.
