the type of protocol messages the RSTP node transmits, as described
below:
- STP Mode – If the switch receives an 802.1D BPDU (i.e., STP
BPDU) after a port’s migration delay timer expires, the switch
assumes it is connected to an 802.1D bridge and starts using only
802.1D BPDUs.
- RSTP Mode – If RSTP is using 802.1D BPDUs on a port and
receives an RSTP BPDU after the migration delay expires, RSTP
restarts the migration delay timer and begins using RSTP BPDUs on
that port.
Command Attributes
Basic Configuration of Global Settings
•
Spanning Tree
State
– Enables/disables STA on this switch.
(Default: Enabled)
•
Spanning Tree Type
– Specifies the type of spanning tree used on
this switch:
-
STP
: Spanning Tree Protocol (IEEE 802.1D); i.e., when this option
is selected, the switch will use RSTP set to STP forced compatibility
mode).
-
RSTP
: Rapid Spanning Tree (IEEE 802.1w); RSTP is the default.
•
Priority
– Bridge priority is used in selecting the root device, root port,
and designated port. The device with the highest priority becomes the
STA root device. However, if all devices have the same priority, the
device with the lowest MAC address will then become the root device.
(Note that lower numeric values indicate higher priority.)
