Uplink Ports: 4 x 10GbE SFP+ ports (Note: The '4SFP56' in the description might be a typo or refer to specific module support, as the standard 6300F often comes with 10GbE SFP+ or 30GbE SFP56 options. Based on typical configurations for '6300F', 4x10GbE SFP+ is more common. If it strictly means SFP56, the speed would be higher.)
