The Cisco C9300-NM-8X is a high-performance network module designed to expand the capabilities of the Cisco Catalyst 9300 series switches. Featuring 8 × 10G SFP+ ports, this module enables seamless high-speed uplinks, stacking, and aggregation, providing flexible connectivity options for enterprise and campus networks.
Plugged in and worked immediately. No issues to report. My c9300 recognized it immediately and after the prerequisite command to use 3rd party SFPs it is now working without issue.
