Spanning tree mode

The Mode option specifies the particular spanning tree protocol that you want to use on the BIG-IP® system. The default value is Pass Through. The possible values are:
Disabled
Specifies that when the BIG-IP system receives spanning tree frames (BPDUs), it discards the frames.
Pass Through
Specifies that when the BIG-IP system receives spanning tree frames (BPDUs), it forwards them to all other interfaces. This is the default setting. When you use Pass Through mode, the BIG-IP system is transparent to spanning tree BPDUs. When set to Pass Through mode, the BIG-IP system is not part of any spanning tree. Note that Pass Through mode is not part of the IEEE spanning tree protocol specifications.
STP
Specifies that the BIG-IP system handles spanning tree frames (BPDUs) in accordance with the STP protocol. This mode allows for legacy systems on the network.
RSTP
Specifies that the BIG-IP system handles spanning tree frames (BPDUs) in accordance with the RSTP protocol.
MSTP
Specifies that the BIG-IP system handles spanning tree frames (BPDUs) in accordance with the MSTP protocol.
When you set the mode to MSTP or RSTP, and a legacy bridge running STP is subsequently added to the spanning tree, the applicable BIG-IP system interface automatically changes to running STP. However, you can manually reset an interface to resume operation in RSTP or MSTP mode if the legacy bridge is later removed from the spanning tree.
