CrossFire 8730 Switch Reference Guide, DOC-7047 v. 1.1 Switch Configuration
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 67.
IEEE STP Uses Bridge Functional Address
•
Yes:
Sets IEEE Spanning Tree to use the Bridge Functional Address.
•
No:
Sets IEEE Spanning Tree to use the standard IEEE STP Address.
Bridge Priority
Enter a priority value for this switch. The bridge with the lowest priority value in
an STP becomes the root. (To change individual port priorities, enter the Port
Spanning Tree Parameters screen.)
Range: 0–65535
Default: 32768
Bridge Hello Time (in Seconds)
Enter a time between configuration messages when this switch is root. The
minimum value may not be less than 1. The maximum may not be more than the
lower of 10 or Switch Maximum Message Age/2–1. The upper range limit that
appears reflects the value currently selected for Switch Maximum Message Age.
Default: 2
Bridge Maximum Message Age (in Seconds)
Enter the maximum message age advertised when this switch is root. The minimum
value may not be less than the higher of 6 or (2 x (Switch Hello Time + 1)). The
maximum may not be more than the lower of 40 or (2 x (Switch Forward Delay –
1)). The range limits that appear reflect the values currently selected for Switch
Hello Time and Switch Forward Delay.
Default: 20
