Concentrate Ethernet access connections and higher-speed aggregation links in one fixed platform. Cisco NCS 540 configuration SD-SSSNT-N54024ZM provides 24 x 1/10GE interfaces for dense access connectivity, plus 8 x 10/25GE interfaces for higher-capacity aggregation. Two 100GE interfaces provide the highest-speed links in the stated interface mix. The 1/10GE, 10/25GE, and 100GE interface groups let network architects map lower-speed access, 25GE aggregation, and 100GE uplink roles without selecting a chassis that is limited to one Ethernet rate. This port combination is relevant where existing 1GE or 10GE services must remain connected while new 25GE and 100GE paths are introduced. A fixed chassis distinguishes this configuration from a modular system by establishing the interface population at the platform level. The specific mix of 24 access-rate interfaces, 8 intermediate-rate interfaces, and 2 high-capacity interfaces is the defining hardware characteristic. It provides 34 stated Ethernet interfaces across three speed classes for carrier-grade routing environments where interface density and uplink rate must be evaluated together.
