FS728TP Smart Switch Software Administration Manual
4-36 Configuring Switching Settings
v1.1, September 2009
– Enable – Enables a point-to-point link, or configure to automatically establish a point-
to-point link. To establish communications over a point-to-point link, the originating
PPP first sends Link Control Protocol (LCP) packets to configure and test the data
link. After a link is established and optional facilities are negotiated as needed by the
LCP, the originating PPP sends Network Control Protocol (NCP) packets t o select and
configure one or more network layer protocols. When each of the chosen network
layer protocols has been configured, packets from each network layer protocol can be
sent over the link. The link remains configured for communications until explicit LCP
or NCP packets close the link, or until some external event occurs. This is the actual
switch port link type. It may differ from the administrative state.
– Disables – Disables point-to-point link.
–Auto – Enables the device to automatically establish a point-to-point link. This is the
default value.
•Point-to-Point Operational S tatus – Di splays the point-to-point operational status which
depends on the connecting link.
•Activate Pro t ocol Migratio n – Activate sending Link Control Protocol (LCP) packets to
configure and test that the data link is enabled.
2. Select the interface.
3. Select the Point-to-Point Admin Status from the list in the provided field in the first row.
4. To configure and test the data link, check Activate Protocol Migration in the provided field
in the first row.
5. Click APPLY to update the device.
MST Configuration
Multiple Spanning Tree (MST) allows the user to group and associate VLANs to spanning tree
instances. Each Spanning Tree Ins t ance has an independent topology of other Spanning Tree
Instances. The architecture provides multiple forwarding paths for data traffic, thus enabling load
balancing in the network and fault tolerance provision. For example, while port A is blocked in
one STP instance, the same port can be placed in the Forwarding state in another STP instance.
To define MSTP:
1. Click Switching > STP > Advanced > MST Configuration. The MST Configuration screen
displays:
The MST Configuration screen contains the following fields:
•MST ID – Specifies the instance to which the VLAN is assigned.
