Does it support Layer 3 routing protocols?

Yes, as a managed Layer 3 switch, it offers 12K MAC addresses, 32 IP interfaces, 2K routes via RIP v1/v2, OSPF (2 areas, 4 virtual interfaces/area, 2 neighbors/interface), and PIM-DM multicast routing, plus IGMP v1/v2 for efficient traffic handling.

How many units can be stacked and managed?

Up to 8 units can be stacked using 3Com XRN technology, providing up to 384 10/100 ports managed as a single IP entity with 2 Gbps full-duplex stacking bandwidth, simplifying large-scale deployments.

What management features are available?

Supports SNMP v3, Telnet, RMON II, Syslog, IPv6 management (pingv6, tracertv6, Telnetv6, TFTPv6), IEEE 802.1X, RADIUS, ACLs, MD5 authentication, and software like 3Com Network Access Manager and Switch Manager for clustering.

What are the physical and environmental specs?

1U rackmount (43.6 mm height), 19-inch chassis with included rack kit, external AC 100-240V 50/60 Hz power. Operating temperature 0°C to 40°C, storage -10°C to 70°C, compliant with EN 55022 Class A and IEC 60950-1.

Is it suitable for enterprise security needs?

Yes, with IEEE 802.1X, RADIUS authentication, ACLs, MD5, per-port status LEDs, and advanced QoS (8 queues/port, 802.1p), it secures and prioritizes traffic in converged enterprise networks.
