S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch Models GS308T and GS310TP

Configuration Examples User Manual346

• Server Address. 192.168.10.23

• Secret Configured. Yes

•

Secret. secret123

• Active. Primary

For more information, see

Manage the RADIUS Settings on page 201.

7. Click the Add button.

8. On the

Authentication List page, configure the default list to use RADIUS as the first

authentication method. (See

Configure Authentication Lists on page 213.)

This example enables 802.1X-based port security on the switch and prompts the hosts

connected on ports g5-g8 for an 802.1X-based authentication. The switch passes the

authentication information to the configured RADIUS server

Multiple Spanning Tree Protocol

Spanning Tree Protocol (STP) runs on bridged networks to help eliminate loops. If a bridge

loop occurs, the network can become flooded with traffic. IEEE 802.1s Multiple Spanning

Tree Protocol (MSTP) supports multiple instances of spanning tree to efficiently channel

VLAN traffic over different interfaces. Each instance of the spanning tree behaves in the

manner specified in IEEE 802.1w, Rapid Spanning Tree, with slight modifications in the

working but not the end effect (chief among the effects is the rapid transitioning of the port to

the forwarding state).

The difference between the RSTP and the traditional STP (IEEE 802.1D) is the ability to

configure and recognize full-duplex connectivity and ports that are connected to end stations,

resulting in rapid transitioning of the port to the Forwarding state and the suppression of

opology Change Notification.

These features are represented by the parameters

pointtopoint and edgeport. MSTP is compatible to both RSTP and STP. It behaves in a way

that is appropriate for STP and RSTP bridges.

An MSTP bridge can be configured to behave entirely as a RSTP bridge or an STP bridge.

So, an IEEE 802.1s bridge inherently also supports IEEE 802.1w and IEEE 802.1D.

The MSTP algorithm and protocol provide simple and full connectivity for frames assigned to

any VLAN throughout a bridged LAN comprising arbitrarily interconnected networking

devices, each operating MSTP, STP

, or RSTP. MSTP allows frames assigned to different

VLANs to follow separate paths, each based on an independent Multiple Spanning Tree

Instance (MSTI), within Multiple Spanning Tree (MST) regions composed of LANs and or

MSTP bridges. These regions and the other bridges and LANs are connected into a single

Common Spanning Tree (CST). (IEEE DRAFT P802.1s/D13)

MSTP connects all bridges and LANs with a single Common and Internal Spanning Tree

(CIST).

The CIST supports the automatic determination of each MST region, choosing its

maximum possible extent.

The connectivity calculated for the CIST provides the CST for

interconnecting these regions, and an Internal Spanning Tree (IST) within each region.
