Features and Benefits of Cisco 25G, QSFP and QSFP28 Modules

The Cisco Catalyst 9500 Series Switches are the industry’s first purpose-built fixed-configuration 25G, 40G, and 100G line of switches for enterprise-class core and aggregation layers.

1. The Cisco Catalyst 9500 Series offers customers a wide variety of high-density, low-power switches and optics for both standalone and Cisco Software-Defined Access deployments.
2. The Cisco Catalyst 9500 Series Switches are based on the Cisco Unified Access Data Plane (UADP) ASIC architecture, which not only protects your investment but also allows greater scale and higher throughput.
3. The Cisco Catalyst 9500 Series delivers unmatched table scale (MAC, route, and Access Control List [ACL]) and buffering for enterprise applications.
4. The Cisco Catalyst 9500 Series includes nonblocking 40G and 100G QSFP+ and QSFP28, and 1G, 10G, and 25G SFP, SFP+, and SFP28 switches with granular port densities that fit diverse campus needs.

The Cisco Catalyst 9300 Series Switches support optional 4-port 25G network modules for uplink ports only. The default switch configuration does not include the network module. When you purchase the switch, you can choose from the available network modules.
