What is the switching performance?

Provides 1280 Gbps bandwidth and 952 Mpps forwarding rate with low-latency cut-through switching under 1 microsecond for 64-byte packets and 9216-byte jumbo frames. Supports store-and-forward modes, 128 load-sharing trunks, and 4094 VLANs for non-blocking Layer 2/3 operations in enterprise data centers.

Does it support stacking?

Yes, high-speed 160 Gbps SummitStack-V stacking with distributed forwarding allows up to 64 ports per switch and 448 ports in a stack. Uses front-panel ports for longer-distance stacking up to 40km with 10GBASE-ER SFP+, ideal for scalable data center topologies.

What operating system is used?

ExtremeXOS modular OS, shared across Summit and BlackDiamond switches, offers high availability, IPv4/IPv6 unicast/multicast routing, and simplified management via CLI, SNMP v1/v2c/v3, and ScreenPlay XML. Includes security like NetLogin and CLEAR-Flow rules.

What are the physical specs and power options?

1RU rack-mountable fixed chassis with back-to-front airflow, 2x hot-swappable AC PSUs (10927), and 3x fans (17112). Low power consumption with optimized cooling; also supports motion sensor for LED control and grounding stud for secure installations.

What security and management features are included?

ExtremeXOS provides Identity Management, LLDP, Kerberos snooping, sFlow sampling, CLEAR-Flow engine, and Wide Key ACLs. Management via 10/100/1000 Ethernet port, RS-232 serial console, and USB for storage, ensuring compliance with CISPR 22/24 Class A.
