How does stacking work on this switch?

Uses 3 matrix connectors to stack up to 4 units into a single virtual switch with 96 ports total. Compatible with SuperStack II Switch 1100/3300, it simplifies management via one interface while providing resilient, high-capacity Layer 2 switching at 2.8 Gbps.

What is the switching performance?

Delivers 2.8 Gbps switching capacity and 1.3 Mpps forwarding rate. Elastic buffering and flow control ensure optimal performance under varying loads, with autosensing on all ports for 10/100 Mbps operation.

What management features are available?

Web-based monitoring and control, embedded RMON for statistics, and included 3Com Network Supervisor software. Supports SNMP, Telnet, and console access for comprehensive stack-wide configuration and troubleshooting.

Which protocols does it support?

IEEE 802.1D spanning tree, 802.1p prioritization, 802.1Q VLANs, IGMP snooping/GMRP for multicast, and Fast IP for policy enforcement. Dual queues handle multimedia traffic efficiently.

What is the form factor and physical design?

1RU rackmount chassis, stackable design fits standard 19-inch racks. Compact size reduces space needs, with front-to-back airflow for data center compatibility.
