Description
Syntax
Document No. 10-300090, Issue 1
Global Configuration.
Forces a bridge port to send out RSTP BPDUs. By forcing a bridge port to
send RSTP BPDUs, you can determine whether legacy 802.1D bridges are
present on a LAN segment.
If you remove a legacy 802.1D bridge from a segment, other RSTP bridges
on the segment cannot detect the removal so they continue sending STP
BPDUs. However, if you force a bridge port to send RSTP BPDUs, they
trigger other RSTP bridges on the segment to generate RSTP BPDUs again.
If the switch is running common Spanning Tree, this command has no
effect.
