ethernet-service nni
Configures the vendor TPID value and the legacy BPDU processing status for a VLAN Stacking Network
Network Interface (NNI).
ethernet-service nni {slot/port1[-port2] | agg_num} [tpid value] [{stp | gvrp} legacy-bpdu {enable |
disable}]
Syntax Definitions
slot/port1 The slot number for the module and the physical port number on that
module (e.g., 3/1 specifies port 1 on slot 3).
-port2 The last port number in a range of ports that you want to configure on
the same slot (e.g, 3/1-4 specifies ports 1, 2, 3, and 4 on slot 3).
agg_num The link aggregate ID number (0–31).
value Specifies the TPID value of the port.
stp Specifies Spanning Tree legacy BPDU support.
gvrp Specifies GVRP legacy BPDU support.
enable Enables the specified legacy BPDU support.
disable Disables the specified legacy BPDU support.

Usage Guidelines
• This command only applies to ports configured as VLAN Stacking NNI ports.
• Enable legacy BPDU support only on VLAN Stacking network ports that are connected to legacy
BPDU switches. Enabling legacy BPDU between AOS switches may cause flooding or an unstable
network.
• If legacy BPDU is enabled on a network port while at same time BPDU flooding is enabled on user
ports, make sure that tagged customer BPDUs are not interpreted by intermediate switches in the
provider network.
