Chapter 11 Spanning Tree Protocol
11.6 Configure Multiple Rapid Spanning Tree Protocol
To configure MRSTP, click MRSTP in the Advanced Application > Spanning Tree Protocol screen. See Section 11.1 on page 99 for more information on MRSTP.
Figure 55 Advanced Application > Spanning Tree Protocol > MRSTP
The following table describes the labels in this screen.

LABEL | DESCRIPTION |
Status | Click Status to display the MRSTP Status screen (see Figure 54 on page 108). |
|
|
Tree | This is a read only index number of the STP trees. |
|
|
Active | Select this check box to activate an STP tree. Clear this checkbox to disable an |
| STP tree. |
| Note: You must also activate Multiple Rapid Spanning Tree in the |
| Advanced Application > Spanning Tree Protocol > |
| Configuration screen to enable MRSTP on the Switch. |
|
|
Bridge Priority | Bridge priority is used in determining the root switch, root port and designated port. |
| The switch with the highest priority (lowest numeric value) becomes the STP root |
| switch. If all switches have the same priority, the switch with the lowest MAC |
| address will then become the root switch. Select a value from the |
| box. |
| The lower the numeric value you assign, the higher the priority for this bridge. |
| Bridge Priority determines the root bridge, which in turn determines Hello Time, |
| Max Age and Forwarding Delay. |
|
|
Hello Time | This is the time interval in seconds between BPDU (Bridge Protocol Data Units) |
| configuration message generations by the root switch. The allowed range is 1 to |
| 10 seconds. |
