2.7.17 Configuring link type
Two interfaces connected by a point-to-point link can quickly transit to forward status by
transmitting synchronization packets. By default, MSTP configures the link type of interfaces
according to duplex mode. The full duplex interface is considered as the point-to-point link,
and the half duplex interface is considered as the shared link.
You can manually configure the current Ethernet interface to connect to a point-to-point link,
but the system will fail if the link is not point to point. Generally, we recommend configuring
this item in auto status and the system will automatically detect whether the interface is
connected to a point-to-point link.
Configure the link type for the ISCOM2600G-HI series switch as below.

2.7.18 Configuring root interface protection
The network will select a bridge again when it receives a packet with higher priority, which
influents network connectivity and also consumes CPU resource. For the MSTP network, if
someone sends BPDUs with higher priority, the network may become unstable due to
continuous election.
Generally, priority of each bridge has already been configured in network planning phase. The
nearer a bridge is to the edge, the lower the bridge priority is. So the downlink interface
cannot receive the packets higher than bridge priority unless under someone attacks. For these
interfaces, you can enable rootguard to refuse to process packets with priority higher than
bridge priority and block the interface for a period to prevent other attacks from attacking
sources and damaging the upper layer link.
Configure root interface protection for the ISCOM2600G-HI series switch as below.
