CHAPTER 1 | Introduction Description of Software Features Table 1: Key Features (Continued) Feature Description Spanning Tree Algorithm Supports standard STP, Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Trees (MSTP) Virtual LANs Up to 4K using IEEE 802.1Q, port-based, protocol-based, private VLANs, and voice VLANs, and QinQ tunnel Traffic Prioritization Queue mode and CoS configured by Ethernet type, VLAN ID, TCP/ UDP port, DSCP, ToS bit, VLAN tag priority, or port Qualify of Service Supports Differentiated Services (DiffServ), and DSCP remarking Link Layer Discovery Protocol Used to discover basic information about neighboring devices Multicast Filtering Supports IGMP snooping and query, MLD snooping, and Multicast VLAN Registration DESCRIPTION OF SOFTWARE FEATURES The switch provides a wide range of advanced performance enhancing features. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. Storm suppression prevents broadcast, multicast, and unknown unicast traffic storms from engulfing the network. Untagged (port-based), tagged, and protocol-based VLANs provide traffic security and efficient use of network bandwidth. CoS priority queueing ensures the minimum delay for moving real-time multimedia data across the network. While multicast filtering provides support for real-time network applications. Some of the management features are briefly described below. CONFIGURATION BACKUP AND RESTORE You can save the current configuration settings to a file on the management station (using the web interface) or a TFTP server (using the console interface through Telnet), and later download this file to restore the switch configuration settings. AUTHENTICATION This switch authenticates management access via a web browser. User names and passwords can be configured locally or can be verified via a remote authentication server (i.e., RADIUS or TACACS+). Port-based authentication is also supported via the IEEE 802.1X protocol. This protocol uses Extensible Authentication Protocol over LANs (EAPOL) to request user credentials from the 802.1X client, and then uses the EAP between the switch and the authentication server to verify the client's right to access the network via an authentication server (i.e., RADIUS or TACACS+ server). Other authentication options include HTTPS for secure management access via the web, SSH for secure management access over a Telnet-equivalent connection, SNMP Version 3, IP address filtering for SNMP/Telnet/web management access, and MAC address filtering for port access. - 24 -
