Bpdu Tunnel Configuration; Configuring A Bpdu Tunnel - 3Com 5500-EI PWR Install Manual

Caution:
To prevent the devices in the service provider network from processing the tunnel packets as other
protocol packets, the MAC address of a tunnel packet must be a multicast address uniquely assigned to
the BPDU tunnel in the service provider network.

BPDU Tunnel Configuration

You can establish BPDU tunnels between Switch 5500-EI series Ethernet switches for the packets of
the following protocols:
LACP (link aggregation control protocol)
STP (spanning tree protocol)
HGMP-related protocols, including: NDP (neighbor discovery protocol), NTDP (neighbor topology
discovery protocol), cluster MRC (cluster member remote control), and HABP (Huawei
authentication bypass protocol)
Proprietary protocols of other vendors, including CDP (CISCO discovery protocol), PAGP (port
aggregation protocol), PVST (per-VLAN spanning tree), VTP (VLAN trunk protocol), and UDLD
(uni-directional link discovery)
Configuration Prerequisites
The edge devices can communicate with the user devices properly.

Configuring a BPDU Tunnel

Follow these steps to configure a BPDU tunnel:
To do...
Enter system view
Configure a private multicast
MAC address for packets
transmitted along the tunnel
Enter Ethernet port view
Enable BPDU tunnel for
packets of a specific protocol
Use the command...
system-view
bpdu-tunnel tunnel-dmac
mac-address
interface interface-type
interface-number
bpdu-tunnel protocol-type
3-3
Remarks
—
Optional
By default, the destination MAC
address for packets transmitted
along a BPDU tunnel is
010f-e200-0003.
—
Required
By default, BPDU tunnel is
disabled for packets of any
protocol.
