Chapter 4. Advanced Management

This chapter deals with the advanced management of the switch, via the console mode or telnet connection. See Chapter 5. Web-Based Management for information on managing the switch through your web browser.

The following sections describe the these advanced topics for management of the IntraCore 3524:

•Spanning Tree Protocol

•SNMP and RMON Management

•Security Management

•VLAN Management

•Multicast Management

4.1Spanning Tree Protocol

The Spanning Tree Protocol (STP) is a part of the IEEE 802.1D standard that provides for redundancy in a bridged LAN by allowing multiple links between points in the LAN.

Without the use of STP, multiple links in a bridged network will result in bridging loops, which can generate excess broadcast traffic that can bring down an entire network. See Chapter 7. Switching Concepts for a more detailed explanation.

4.1.1 Enabling and Disabling STP

The switch is shipped with Spanning Tree enabled on all ports by default. To enable or disable STP on your switch, use the following procedure:

1.Type c to open the Configuration Menu.

2.Open the Spanning Tree Configuration Menu by typing s in the Configuration Menu.

3.Type t to toggle STP to enabled or disabled.

When you disable STP, you are prompted to confirm the change. The STP status is changed. The status is displayed near the top of the Spanning Tree Configuration Menu.

4.1.2Configuring Spanning Tree Parameters

Important! You should attempt to set these parameters only if you have experience with the 802.1D specification.

To view the Spanning Tree Configuration Menu, as shown below, type s in the Configuration Menu.
