High-performance, Fast Ethernet solution
- High-performance, 48 port Fast Ethernet wire-speed solution which is ideal for resilient stacking, cost-effective wiring closet solutions, desktop connectivity and high-speed network backbone traffic aggregation.
- Secure switching using edge authentication via 802.1x, private VLANs, Voice VLANs, Protocol VLANs, and SNMPv3. Robust security capabilities provided through flow-based . IP, and MAC ACLs, port-based MAC security, RADIUS and TACACS+ remote authentication, SSL/SSH encryption, and IP-based management access filtering.
- Supports open industry standards including advanced Quality of Service (L2, L3-aware), Multiple Spanning Trees, SNTP and IP multicast support, Dynamic Link Aggregation (LACP), dynamic VLAN configurations, port mirroring and Rapid Spanning Tree Protocol
- Versatile remote management uses an industry-standard CLI, an embedded web interface or an SNMP-based management application.
- Virtual Cable TesterTM by Marvell for diagnosing copper connectivity and detecting problems and fiber transceiver diagnostics for troubleshooting transceiver problems.
