OmniSwitch AOS Release 7 Network Configuration Guide

June 2013

The following diagram shows a switch running in the per-VLAN Spanning Tree mode and shows Span-
ning Tree participation for both fixed and tagged ports.

Per VLAN (single and 802.1Q) Spanning Tree Example

In the above example, STP2 is a single Spanning Tree instance since VLAN 5 contains only fixed ports.
STP 3 and STP 4 are a combination of single and 802.1Q Spanning Tree instances because VLAN 2
contains both fixed and tagged ports. On ports where VLAN 2 is the default VLAN, BPDU are not tagged.
on ports where VLAN 2 is a tagged VLAN, BPDU are also tagged.

Using Per-VLAN Spanning Tree Mode with PVST+

In order to interoperate with Cisco's proprietary Per Vlan Spanning Tree (PVST+) mode, the current
Alcatel-Lucent per-VLAN Spanning Tree mode allows OmniSwitch ports to transmit and receive either
the standard IEEE BPDUs or Cisco's proprietary PVST+ BPDUs. When the PVST+ mode is enabled, a
user port operates in the default mode initially until it detects a PVST+ BPDU, which automatically
enables the port to operate in the Cisco PVST+ compatible mode.

The PVST+ compatibility mode allows OmniSwitch ports to operate in the per-VLAN mode when
connected to another OmniSwitch or in the Cisco PVST+ mode when connected to a Cisco switch. As a
result, both the Alcatel-Lucent per-VLAN and Cisco PVST+ modes can co-exist on the same OmniSwitch

and

interoperate correctly with a Cisco switch using the standard Spanning Tree protocols (STP or RSTP).

Note.

In the flat Spanning Tree mode, both the OmniSwitch and Cisco switches can interoperate

seamlessly using the standard MSTP protocol.
