What is the difference between the Summit 5i 11504 and other 11500-series models?

The 11504 features 12 fixed 1000Base-SX ports (MT-RJ fiber) with 4 unpopulated GBIC slots, compared to the 11501 which offers 100/1000Base-T copper ports. The 11504 is optimized for fiber-based metro and data center deployments requiring longer distances and higher reliability than copper connections.

Does the Summit 5i support stacking or clustering?

The Summit 5i 11504 does not support modern SummitStack methods documented for newer Extreme switches. However, it supports dual switch configurations with ExtremeWare images and Extreme Standby Router Protocol (ESRP) for high-availability deployments using separate physical switches.

What QoS features are included in the Basic Layer 3 Software License?

The Basic Layer 3 Software includes Policy-Based QoS with eight queues per port, bandwidth provisioning per port, and application prioritization. Full Layer 3 features like advanced routing protocols require the Full Layer 3 Software License upgrade (model 11509).

How many VLANs can the Summit 5i support?

The Summit 5i supports up to 1,024 IEEE 802.1Q VLANs, enabling comprehensive network segmentation for multi-tenant environments, departmental isolation, and service provider deployments. This capacity supports enterprise-scale network designs without VLAN exhaustion.

What is the maximum number of MAC addresses the switch can learn?

The Summit 5i 11504 supports up to 128,000 Layer 2 addresses, providing substantial capacity for large enterprise networks with thousands of connected devices. This capacity ensures the switch can handle complex network topologies without address table limitations.

Is the Summit 5i suitable for server load balancing applications?

Yes, the Summit 5i includes built-in server load balancing and web cache redirection capabilities at wire speed. These features enable efficient distribution of traffic across multiple servers in co-location and hosting environments without external load balancing appliances.

What security features does the Summit 5i provide?

The switch includes wire-speed access control lists (ACLs), user policy and host integrity enforcement, and instrumentation to react to network intrusions. The ExtremeWare software is hardened against common attacks including pepsi5, Winnuke, Simping, and Land attacks.
