6. Configure the format of MSTP
Command
Port Mode
spanning-tree format standard
spanning-tree format privacy
spanning-tree format auto
no spanning-tree format
Explanation
Set the value for switch forward delay
time.
Set the Hello time for sending BPDU
messages.
Set Aging time for BPDU messages.
Set Maximum number of hops of
BPDU messages in the MSTP region.
Explanation
Set the port link type.
Set and cancel the port to be an
boundary port. bpdufilter receives the
BPDU discarding; bpduguard receives
the BPDU will disable port; no parameter
receives the BPDU, the port becomes a
non-boundary port.
Explanation
Configure the format of port
spanning-tree packet, standard format
is provided by IEEE, privacy is
compatible with CISCO and auto
means the format is determined by
checking the received packet.
