What is the switching performance?

The switch delivers a 17.5 Gbps non-blocking switch fabric with a 10.1 million packets per second forwarding rate, ensuring wire-speed Layer 2/3 performance on all ports, powered by the 'i' series chipset.

Does it support VLANs and QoS?

Yes, it supports 4,096 IEEE 802.1Q VLANs and eight queues per port. ExtremeWare provides policy-based QoS, IETF DiffServ, IEEE 802.1p, server load balancing, and ACLs for traffic prioritization and security.

What power options are available?

SKU 15501 features a single internal power supply, with optional dual internal power supplies for redundancy. This enhances fault tolerance alongside redundant GBIC ports and Extreme Standby Router Protocol.

What Layer 3 capabilities does it offer?

Basic Layer 3 ExtremeWare Software License enables IP/IPX routing, VLAN switching/routing, multiple spanning trees, load-sharing trunks, and up to 128,000 Layer 3 addresses for edge service provisioning.

What is the form factor and MAC capacity?

It's a 2 RU rackmount chassis, compact for edge deployment. Supports up to 128,000 Layer 2 addresses, ideal for large-scale networks in enterprises, MDUs, or data centers.
