Configuration restrictions and guidelines • Settings made in Layer 2 Ethernet interface view or Layer 2 aggregate interface view take effect only on the current port. • Before you enable BPDU tunneling for DLDP, EOAM, GVRP, HGMP, LLDP, or STP on a port, disable the protocol on the port first. • Because PVST is a special STP protocol, you must do two things before you enable BPDU tunneling for PVST on a port: first, disable STP; second, 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. Configuration procedure You can enable BPDU tunneling for different protocols in different views. Enabling BPDU tunneling for a protocol in Layer 2 Ethernet interface view Step 1. Enter system view. Command system-view Remarks N/A 2. Enter Layer 2 Ethernet interface view. interface interface-type interface-number N/A 3. Enable BPDU tunneling for a protocol. bpdu-tunnel dot1q { cdp | dldp | eoam | gvrp | hgmp | lacp | lldp | pagp | pvst | stp | udld | vtp } Disabled by default. Enabling BPDU tunneling for a protocol in Layer 2 aggregate interface view Step 1. Enter system view. 2. Enter Layer 2 aggregate interface view. 3. Enable BPDU tunneling for a protocol on the Layer 2 aggregate interface. Command system-view interface bridge-aggregation interface-number bpdu-tunnel dot1q { cdp | gvrp | hgmp | pvst | stp | vtp } Remarks N/A N/A Disabled by default. Configuring destination multicast MAC address for BPDUs By default, the destination multicast MAC address for BPDUs is 0x010F-E200-0003. You can change it to 0x0100-0CCD-CDD0, 0x0100-0CCD-CDD1, or 0x0100-0CCD-CDD2. To configure destination multicast MAC address for BPDUs: 95
