What is the switching performance?

Aggregated switch bandwidth is 320 Gbps with 166.7 Mpps forwarding rate and under 4μs latency for 64-byte packets. Supports jumbo frames to 9216 bytes and 128 trunks with up to 8 members for load balancing.

Does it support VLANs and security features?

Supports 4,094 VLANs (port, protocol, 802.1Q) and comprehensive security with 4,192 ingress/512 egress ACL rules, meters per 24 ports. Includes threat detection and 32K MAC addresses for robust segmentation.

What management OS is used?

Runs ExtremeXOS modular OS for high resiliency, continuous uptime, and manageability. Supports protocols like MPLS/H-VPLS, IEEE AVB, E-Line, with 1GB ECC DRAM and Compact Flash.

What are the power and form factor details?

1RU rack-mountable with dual hot-swappable AC/DC power supplies and hot-swappable fan tray. Flexible PoE+ support via IEEE 802.3at, though primarily fiber-focused.

Is stacking supported?

Yes, via optional SummitStack modules in slots for 40/80 Gbps high-speed stacking up to 8 units, or longer-distance SummitStack-V, managed as one logical switch.
