Description
Configures all access ports connected to Layer 2 hosts
as edge ports. Edge ports immediately transition to the
forwarding state without passing through the blocking
or learning state at linkup. By default, spanning tree
ports are normal port types.
Configures all interfaces connected to Layer 2 switches
and bridges as spanning tree network ports. If you
enable Bridge Assurance, it automatically runs on
network ports. By default, spanning tree ports are
normal port types.
If you configure interfaces connected to Layer
Note
2 hosts as network ports, those ports
automatically move into the blocking state.
