What is the switching performance?

The switch delivers 328 Gbps aggregated switching capacity and 166.7 Mpps forwarding rate with less than 4 microsecond latency for 64-byte packets. It supports jumbo frames up to 9216 bytes, 32K MAC addresses, and 12K IPv4 LPM entries for high-throughput operations.

Does it support PoE and power budget?

Yes, all 48 Gigabit ports provide IEEE 802.3at PoE-plus up to 30W each. It features AC PoE PSU with one unpopulated slot for dual hot-swappable AC/DC supplies, enabling up to 760W total PoE budget in redundant configurations.

What management features are included?

Runs ExtremeXOS modular OS with protocols like MPLS/H-VPLS, EAPS, ESRP, OSPF, 802.1Q VLANs (4,094), LACP trunks (128, up to 8 members), and LLDP. Includes serial console, 10/100/1000 Ethernet management port, and hot-swappable fan tray.

What QoS capabilities does it offer?

Provides 8 QoS egress queues per port, ingress/egress bandwidth policing per flow/ACL, egress rate shaping per queue/port, and 4,096 ingress meters per 24 ports with 8 Kbps granularity. Supports 4,192 ingress and 512 egress ACL rules for precise traffic control.

Is it suitable for stacking?

Yes, Slot B supports optional SummitStack 40 Gbps or SummitStack-V80 80 Gbps modules for high-speed, voice-grade stacking, or longer-distance SummitStack-V. This enables scalable, resilient fabrics up to multiple switches without performance loss.
