Transmitting BPDUs

You can conﬁgure whether or not this port will transmit BPDUs (Bridge Protocol Data Units). BPDUs are used in the Spanning Tree process. Bridges communicate Spanning Tree Algorithm information via BPDUs. With BPDUs, all network bridges collectively determine the current network topology and communicate with each other to ensure that the topology information is kept current.

1.Click in the Transmit BPDUs selection box to determine if the port will transmit BPDUs.

•If the Transmit BPDUs option is selected, 802.1d and source-routing spanning tree packets are transmitted as usual.

•If the Transmit BPDUs option is not selected, BPDU packets are not transmitted.

NOTE

Disabling the transmission of BPDUs is needed for interoperability with non-802.1d spanning tree protocols (e.g., DEC LanBridge 100).

Source Route Conﬁguration

If the bridge port is conﬁgured for Source Route or Source Route Transparent bridging, you can conﬁgure some of the source route bridging parameters from the Bridge Conﬁguration window.

Ring Number

The Ring Number is the unique network number of the target network segment that the bridge attaches to. Valid entries range from 0-fff (hexadecimal). Individual ports within the ATX Chassis should each be assigned unique values for this ﬁeld.

Bridge Number

The Bridge Number uniquely identiﬁes this bridge port. The Bridge Number you enter should be between the range of 0 and f (hexadecimal).

Spanning Tree Explorer Modes

The Spanning Tree Explorer Span Mode determines how a bridge port behaves when it receives a STE packet (also known as Single Route Explorer packet). You can set the Spanning Tree mode to one of the three possible modes.

Auto	The port will forward an STE packet when it is in the
	Forwarding state; otherwise, it will discard the packet.
	This mode can only be used by a bridge that implements
