BPDU Tunneling Configuration Commands
bpdu-tunnel dot1q stp
Syntax
bpdu-tunnel dot1q stp
undo bpdu-tunnel dot1q stp
View
Ethernet interface view, Layer-2 aggregate interface view, port group view
Default Level
2: System level
Parameters
None
Description
Use the bpdu-tunnel dot1q stp command to enable BPDU tunneling for STP on the current port or
ports.
Use the undo bpdu-tunnel dot1q stp command to disable BPDU tunneling for STP on the port or
ports.
By default, BPDU tunneling for STP is disabled.
Note that:
Configuration made in Ethernet interface view takes effect on the current port only. Configuration
made in Layer-2 aggregate interface view takes effect only on the Layer-2 aggregate interface.
Configuration made in port group view takes effect on all ports in the port group.
Configuration made on an aggregation group member port takes effect after the port exits the
aggregation group. For detailed information about link aggregation, refer to Link Aggregation
Configuration in the Access Volume.
Before you can enable BPDU tunneling for STP on a port, disable STP on the port first.
