SNR S2940-8G-v2 Switch Configuration Guide
MSTP Configuration
abort Quit MSTP region mode and return to Global
mode without saving MSTP region configuration.
exit Quit MSTP region mode and return to Global
mode with saving MSTP region configuration.
no Cancel one command or set initial value.
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 mes-
sages 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 | bp-
duguard ] [recovery <30-3600>]
no spanning-tree portfast
Set and cancel the port to be an boundary port.
bpdufilter receives the BPDU discarding; bp-
duguard 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, stan-
dard format is provided by IEEE, privacy is compatible with
CISCO and auto means the format is determined by check-
ing the received packet.
7. Configure the spanning-tree attribute of port
Command Explanation
Port Mode
spanning-tree cost
no spanning-tree cost
Set the port path cost.
