Mstp Operation Mode Configuration - Huawei Quidway S3100 Series Operation Manual

Operation Manual – MSTP
Quidway S3100 Series Ethernet Switches
Caution:
Once you specify a switch as the root bridge or a secondary root bridge by using the
stp root primary or stp root secondary command, the bridge priority of the switch
is not configurable.
During the selection of root bridge, if multiple switches have the same bridge priority,
the one with the least MAC address will become the root bridge.
II. Configuration example
# Set the bridge priority of the current switch to 4,096 in spanning tree instance 1.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
[Quidway] stp instance 1 priority 4096

1.2.5 MSTP Operation Mode Configuration

A MSTP-enabled switch can operate in one of the following operation modes:
STP-compliant mode: In this mode, the protocol packets sent out of the ports of
the switch are STP packets. If the switched network contains STP-enabled
switches, you can configure the current MSTP-enabled switch to operate in this
mode by using the stp mode stp command.
RSTP-compliant mode: In this mode, the protocol packets sent out of the ports of
the switch are RSTP packets. If the switched network contains RSTP-enabled
switches, you can configure the current MSTP-enabled switch to operate in this
mode by using the stp mode rstp command.
MSTP mode: In this mode, the protocol packets sent out of the ports of the switch
are MSTP packets, or STP packets if the ports have STP-enabled switches
connected. In this case, the multiple spanning tree function is enabled as well.
