12-2
By default, BPDU tunneling for any protocol is disabled.
Note that:
Settings made in Ethernet interface view or Layer 2 aggregate interface view take effect only on
the current port; settings made in port group view take effect on all ports in the port group.
You cannot enable BPDU tunneling on a member port of a service loopback group.
Before enabling 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, before enabling
BPDU tunneling for PVST on a port, you must also disable STP and then enable BPDU tunneling
for STP on the port first.
Before enabling BPDU tunneling for LACP on a member port of a link aggregation group, remove
the port from the link aggregation group first.
