The N77-F312CK-26 is a Nexus 7700 F3-Series line card in the Cisco interface cards range, built with 12 ports of 100 Gigabit Ethernet that take CPAK optics. It occupies one I/O module slot and goes into any Nexus 7700 chassis.
Each module forwards 1.8 billion packets per second of Layer 2 and Layer 3 traffic for IPv4 and IPv6, with up to 1.2 Tbps of data throughput. Every port has 4 ingress and 8 egress queues, 144 MB of VOQ buffer sits on the module, and jumbo frames reach 9216 bytes.
Three CPAK optic types fit the ports: an 850 nm multimode type on a 24-fibre MTP/MPO connector reaching 100 m on OM3 and 150 m on OM4, a 1310 nm single-mode duplex type reaching 10 km, and an extended 1310 nm single-mode type reaching 25 km.
The forwarding engine holds 64K MAC entries, 4096 VLANs per VDC, 64K IPv4 entries, 32K IPv6 entries, 64K adjacency entries and 16K ACL entries. Features include FabricPath, FEX support, integrated FCoE, wire-rate VXLAN, OTV, VPLS, MPLS, LISP and TrustSec SGT processing.
Port density reaches 192 ports of 100GbE in an 18-slot chassis, 96 in a 10-slot, 48 in a 6-slot and 12 in a 2-slot chassis. Its spare part number is N77-F312CK-26=.
