Cisco NCS 5500 400G Line Card - NC57-24DD

The Cisco NC57-24DD is a 400G line card for NCS 5500 chassis, offering 24 400 Gigabit Ethernet ports in QSFP-DD/QSFP28/QSFP+ format, with a switching throughput of 7.2 Tbit/s. It supports OSPF, IS-IS, BGP, 64-way ECMP, MPLS with SR-TE traffic engineering, L3VPN, BFD, and SyncE/IEEE 1588 PTP. Routing scale reaches 2.5 M IPv4 routes or 1 M IPv6 routes in the FIB.

With 24 400GbE ports on a single card, the NC57-24DD differs from the NC-57-18DD-SE by its higher density of pure 400G interfaces, without the latter's 100G/200G ports. It targets operators seeking to maximize 400G capacity in each NCS 5500 chassis slot for inter-data center interconnects and backbone network cores. Genuine Cisco hardware, manufacturer warranty.
