N77-M312CQ-26L is the Cisco Nexus 7700 M3-Series 12-port 100 Gigabit Ethernet module, and its spare form is N77-M312CQ-26L=. It needs QSFP28 modules in the ports, and the supported 100G optics include QSFP-100G-SR4-S, QSFP-100G-LR4-S, QSFP-100G-CWDM4-S, QSFP-100G-PSM4-S and active optical cables.
The module handles up to 1.2 Tbps with 28.8 bpps of Layer 2 and Layer 3 forwarding for both IPv4 and IPv6. Each port has 4 ingress and 8 egress queues, the VOQ buffer is 4 GB, the module carries 8 GB of DRAM, and jumbo frames reach 9216 bytes. Scale reaches 384,000 MAC entries, 2 million IPv4 entries, 1 million IPv6 entries, 128,000 ACL entries, 8000 policers and 4096 VLANs per VDC.
All 12 ports provide IEEE 802.1AE MACsec with a 256-bit AES cipher. The feature set includes VXLAN, GTP hashing, OTV, LISP, MPLS, VPLS, VDCs, Cisco TrustSec with SGT-based ACL processing, CoPP and FabricPath, and the module supports Nexus 2000 Fabric Extenders.
It fits the Nexus 7700 2-, 6-, 10- and 18-slot chassis and needs Cisco Fabric-2 modules and the Nexus 7700 Supervisor 2E. The minimum software is Cisco NX-OS 8.0. A full 18-slot chassis reaches 192 of these 100G ports, a 10-slot reaches 96, a 6-slot reaches 48 and a 2-slot reaches 12. The module takes one I/O slot and measures 1.75 x 15.9 x 21.8 in (4.4 x 40.39 x 55.37 cm) at 12 lb.
