Avaya 106760804 manual Set port spantree force-protocol-migration

Rapid Spanning Tree Protocol

set port spantree force-protocol-migration

Command Mode	Global Configuration.
Description	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.
Syntax	set port spantree force-protocol-migration <mod-swport-range>[...,<mod-
	swport-range>] {802.1D vlan {<vlan-id> name <vlan-name>}}
