Can this switch be stacked with other models?

Yes, it stacks up to four units via matrix connectors to create a 96-port virtual switch. Compatible with existing SuperStack II Switch 1100/3300 units, allowing mixed configurations with unified management through web interface or SNMP.

What is the switching performance?

Switching capacity is 2.8 Gbps with a forwarding rate of 1.3 Mpps and 16K MAC address table entries. Features elastic buffering, trunking for link aggregation, and store-and-forward method to handle heavy loads without packet loss.

What management features are available?

Includes web-based management, embedded RMON, SNMP support, and 3Com Network Supervisor software. Protocols like IGMPv2 snooping, IEEE 802.1D spanning tree, 802.1p prioritization, and resilient links enable efficient monitoring and traffic control.

What is the form factor and power options?

1U rackmount chassis with included rack ears and compact design reducing height by one-third. Supports optional redundant power supply (RPS) via rear connector for high availability in enterprise racks.

Does it support VLANs and multicast?

Yes, supports IEEE 802.1Q VLANs, IGMPv2 snooping/GMRP for multicast filtering, and Fast IP policy enforcement. Dual queues prioritize multimedia traffic, optimizing bandwidth for video and VoIP applications.
