bpdu-tunnel dot1q

Use bpdu-tunnel dot1q to enable BPDU tunneling for a protocol on the ports.

Use undo bpdu-tunnel dot1q to disable BPDU tunneling for a protocol on the ports.

Syntax

In Layer 2 Ethernet interface view or port group view:

bpdu-tunnel dot1q { cdp | dldp | eoam | gvrp | hgmp | lacp | lldp | pagp | pvst | stp | udld | vtp }

undo bpdu-tunnel dot1q { cdp | dldp | eoam | gvrp | hgmp | lacp | lldp | pagp | pvst | stp | udld | vtp }

In Layer 2 aggregate interface view:

bpdu-tunnel dot1q { cdp | gvrp | hgmp | pvst | stp | vtp }

undo bpdu-tunnel dot1q { cdp | gvrp | hgmp | pvst | stp | vtp }

Default

BPDU tunneling for any protocol is disabled.

Parameters

cdp: Specifies CDP.

dldp: Specifies DLDP.

eoam: Specifies EOAM.

gvrp: Specifies GVRP.

hgmp: Specifies HGMP.

lacp: Specifies LACP.

lldp: Specifies LLDP.

pagp: Specifies PAGP.

pvst: Specifies PVST.

stp: Specifies STP.

udld: Specifies UDLD.

vtp: Specifies VTP.

Usage guidelines

Settings made in Layer 2 Ethernet interface view or Layer 2 aggregate interface view take effect only on the Ethernet interface or aggregate interface.

Settings made in port group view take effect on all member ports in the port group.

You cannot enable BPDU tunneling on a member port of a service loopback group.

Before you enable BPDU tunneling for DLDP, EOAM, GVRP, HGMP, LLDP, or STP on a port, disable the protocol on the port first.

To enable BPDU tunneling for PVST (a spanning tree protocol) on a port, disable STP first, and then enable BPDU tunneling for STP on the port.

Do not enable BPDU tunneling for DLDP, EOAM, LACP, LLDP, PAGP, or UDLD on the member port of a Layer 2 aggregation group.

bpdu-tunnel tunnel-dmac

Use bpdu-tunnel tunnel-dmac to configure the destination multicast MAC address for BPDUs.

Use undo bpdu-tunnel tunnel-dmac to restore the default value.

Syntax

bpdu-tunnel tunnel-dmac mac-address

undo bpdu-tunnel tunnel-dmac

Default

The destination multicast MAC address for BPDUs is 0x010F-E200-0003.
