The Cisco Catalyst 9400 Series 12-port 40 Gigabit Ethernet, or 4-port 100 Gigabit Ethernet plus 4-port 40 Gigabit Ethernet line card can be deployed for high-performance and high-density 100G or 40 Gigabit Ethernet aggregations in the campus and in small to medium-sized networks as a core switch. The Cisco Catalyst 9400 Series 12-port 40G Gigabit Ethernet line card supports standard Quad Small Form-Factor Pluggable 28 and Plus (QSFP28 and QSFP+) optics. The ports can be used full 40 Gigabit Ethernet or 100 and 40 Gigabit Ethernet to support phased migration from 40 Gigabit Ethernet to 100 Gigabit Ethernet.
