20 CHAPTER 1: SWITCH FEATURES OVERVIEW RMON Remote Monitoring (RMON) is an industry standard feature for traffic monitoring and collecting network statistics. The Switch software continually collects statistics about the LAN segments connected to the Switch. If you have a management workstation with an RMON management application, the Switch can transfer these statistics to your workstation on request or when a pre-defined threshold is exceeded. Event Notification You can configure your Switch to send you notification when certain events occur. You can receive notification via email, SMS (Short Message Server), or pager. For more information about RMON and Event Notification, see Chapter 7 "Status Monitoring and Statistics". Broadcast Storm Control Broadcast Storm Control is a system that monitors the level of broadcast traffic on that port. If the broadcast traffic level rises to a pre-defined number of frames per second (threshold), the broadcast traffic on the port is blocked until the broadcast traffic level drops below the threshold. This system prevents the overwhelming broadcast traffic that can result from network equipment which is faulty or configured incorrectly. VLANs A Virtual LAN (VLAN) is a flexible group of devices that can be located anywhere in a network, but which communicate as if they are on the same physical segment. With VLANs, you can segment your network without being restricted by physical connections - a limitation of traditional network design. As an example, with VLANs you can segment your network according to: ■ Departmental groups ■ Hierarchical groups ■ Usage groups For more information about VLANs, see Chapter 8 "Setting Up Virtual LANs". Configuration Save and Restore Configuration Save and Restore allows the configuration of your Switch to be saved as a file on a remote server, or to be restored onto the Switch from a remote file.
