Multiple Spanning Tree Protocol (MSTP) Properties Configuration on ESW2-550X Switch
Multiple Spanning Tree Protocol (MSTP) is an extension to Rapid Spanning Tree Protocol (RSTP). MSTP allows for multiple spanning trees through separation of the number of instances. As a result, the device can take 1000 VLANS and reduce this number to many spanning tree instances. The objective of this article is to explain how to configure the properties of the MSTP for on ESW2-550X series switches.
• ESW2-550X-48DC-R • ESW2-550X-48-R
Configuration of the MSTP Properties
Step 1. Log in to the web configuration utility and choose Spanning Tree > MSTP Properties. The MSTP Properties page opens:
Step 2. Enter a user defined spanning tree protocol name in the Region Name field. Regions are one or more Multiple Spanning Tree bridges by which frames can be transmitted. In the above image the Region Name field given is a MAC address of a port that runs MSTP.
Step 3. Enter a revision number from 0 to 65535 into the Revision field. Revision number identifies the current Multiple Spanning Tree (MST) configuration.
Step 4. Enter a number from 1 to 40 into the Max Hops field to set how many hops happen in a region before the bridge protocol data unit packet is discarded. The default is 20.
Note: The IST Active field displays what the region active switch is.
Caution: This only saves your configuration to the running configuration file. This means any changes made will be lost if the device is rebooted. If you wish to save these changes even after a system reboot, you need to copy the running configuration file to the startup configuration file refer to Copy or Save Configuration on ESW2-550X Switch.
