4. Configure MSTP time parameters
Command Explanation
Global Mode
spanning-tree forward-time <time>
no spanning-tree forward-time
Set the value for switch forward delay
time.
spanning-tree hello-time <time>
no spanning-tree hello-time
Set the Hello time for sending BPDU
messages.
spanning-tree maxage <time>
no spanning-tree maxage
Set Aging time for BPDU messages.
spanning-tree max-hop <hop-count>
no spanning-tree max-hop
Set Maximum number of hops of
BPDU messages in the MSTP region.
5. Configure the fast migrate feature for MSTP
Command Explanation
Port Mode
spanning-tree link-type p2p
{auto|force-true|force-false}
no spanning-tree link-type
Set the port link type.
spanning-tree portfast [bpdufilter|
bpduguard]
no spanning-tree portfast
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.
6. Configure the format of MSTP
Command Explanation
Port Mode
spanning-tree format standard
spanning-tree format privacy
spanning-tree format auto
no spanning-tree format
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.
7. Configure the snooping attribute of authentication key
Command Explanation
Port Mode
spanning-tree digest-snooping
no spanning-tree digest-snooping
Set the port to use the authentication
string of partner port. The no restores
to use the generated string.
