6.27 X-RSTP

X-RSTP is a multi-ring RSTP network supporting one root switch and up to two backup root switches for the system. It allows users to establish the multi-linking-path network with up to 20 switches. In addition, the recovery time could be less than

100ms to prevent the losses of data caused by unexpected link-broken.

„ Root: This drop-down menu item allows the user to designate the switch to be the root switch by selecting Enable or the backup root switch by selecting

Backup

.

„ Port: Tick the checkbox of the port to include it into the group for spanning tree algorithm.

„ State: This column field shows the state of the port.

¾ INACTIVE: This port is not ticked to join the spanning tree.

¾

BLOCKING: The port is a backup/redundant port that would cause a switching loop. When the port state is blocking, no user data will be transferred via this port. However, it will change to forwarding state when other links fail.

¾ FORWARDING: The port receiving and transmitting data is a normal operating port. Spanning Tree Protocol still monitors incoming BPDUs that would indicate it should return to the blocking state to prevent a loop.

¾ LINKDOWN: The port linking is disconnected or broken.
