Configuring Global Settings

Global settings apply to the entire switch.
Command Usage
• Spanning Tree Protocol
Uses RSTP for the internal state machine, but sends only 802.1D
BPDUs.
• Rapid Spanning Tree Protocol
RSTP supports connections to either STP or RSTP nodes by monitoring
the incoming protocol messages and dynamically adjusting 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
