P2P The rapid state transitions possible within RSTP depend on whether the port
concerned can only be connected to a specific bridge (it is served by a point-to-point
LAN segment), or can be connected to two or more bridges (it is served by a shared
medium LAN segment).
This function allows the P2P (point-to-point) status of the link to be manipulated
administratively. Select from the following settings:
• True—The port is to be regarded as a point-to-point link.
• False—The port is to be regarded as a shared link.
• Auto—The link type is to be determined by the auto-negotiation between the two
peers.
Edge The edge port is directly connected to end stations will not create a bridging loop in
the network.
• True—Configures the port as an edge port.
• False—Configures the port as a non-edge port.
Apply Click to apply the settings.

Figure 46 RSTP Information
Bridge ID The root switch is determined by bridge ID. The switch with the lowest bridge ID
will become the root switch. The bridgeID is a combination of the bridge priority
number (which is configurable) and the MAC address of the switch. For example, in
the bridgeID “32768.0200.0000.1111,” the bridge priority number is “32768” and the
switch MACaddress is “0200.0000.1111.” The bridge priority default is 32768, and
can only be configured in multiples of 4096.
Root Priority The bridge priority of the switch determined to be the root switch.
