RSTP
IEEE 802.1w Rapid Spanning tree protocol (LACP) provides a loop-free network and
redundant links to the core network with rapid convergence to ensure faster
recovery from failed links, enhancing overall network stability and reliability.
RSTP System Configuration
System Priority: This parameter configures the spanning tree priority globally for
this switch. The device with the highest priority becomes the STP root device.
However, if all devices have the same priority, the device with the lowest MAC
address will then become the root device. Number between 0 - 61440 in
increments of 4096. Therefore, there are 16 distinct values.
Hello Time: Interval (in seconds) at which the root device transmits a
configuration message (BPDU frame). Number between 1-10 (default is 2).
Max Age – The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. That also means the
maximum life time for a BPDU frame. Number between 6-40 (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 –
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: Click on the tick-box 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.
