Spanning Tree for TrBRF Screen

When you select Spanning Tree from the Configuration menu, a list containing available TrBRF VLANs appears. Choose a TrBRF to view or edit from the list before continuing. When you have selected a TrBRF, TrCRFs and ports associated with the BRF may be selected for modification.

STP Participation

Whether this TrBRF participates in the spanning tree protocol and, if so, the protocol to be used. Possible values are No, IEEE, IBM, and Base on Bridging Mode. The default is No.

If STP Participation is set to No, then all TrCRFs with this TrBRF as a parent will be set to forwarding mode. You can then override this by blocking a particular TrCRF.

If STP Participation is set to IEEE or IBM, then the selected protocol will be used to determine the forwarding/blocked mode of the TrCRFs that are configured with an STP mode of auto.

If STP Participation is set to Base on Bridging Mode, then the spanning tree protocol used is based on the bridging mode of the TrCRF. If the bridging mode is SRB, the IBM Spanning Tree Protocol is used. If the bridging mode is SRT, the IEEE 802.1D Spanning Tree Protocol is used.

For a particular TrCRF the protocols selected here can be overridden. See the STP Mode parameter in the section “Spanning Tree for TrCRF Screen” on page 101.
