Fully Manageable
The switch is fully managed, supporting SNMP versions 1, 2c, and 3. The embedded RMON software agents support RMON groups 1 (history), 2 (statistics), 3 (alarms), and 9 (events). The switch supports up to 26 trunking groups, with 16 ports per group. The integral Web server enables Web-based management via a Web browser. This GUI interface enables switch configuration, system dashboard, maintenance, and monitoring. The wide range of management and support features also includes dual image, port mirroring, LLDP, sFlow, UPnP, IPv6, SSH, RADIUS, DHCP Client/DHCPv6 Client, SNTP, cable diagnostics, ping, Syslog, and Telnet client with SSH security.

Support for VLAN and QoS
Support for up to four simultaneous VLANs enables you to segment traffic with port-based, 802.1Q tag-based, or MAC-based VLANs. 802.1p Layer 2 quality of service (QoS) enables prioritization of time-sensitive applications such as VoIP and video.

You get enterprise-class security features, too. 802.1x port-based network access control authenticates devices connecting to your network. The switch also supports SNMPv3 cryptographic security, SSH, and SSL. Plus, you can set up a guest VLAN that enables visitors to access the Internet without also giving them access to the corporate network.

The Gigabit Ethernet Managed Switch features IEEE 802.3az energy-efficient Ethernet, which scales down power consumption during periods of low data activity. This feature adds up to energy savings of up to 50%. Cable length detection adjusts signal strength to the cable length, reducing power consumption on shorter cable runs.
