Description
The Cisco N55-M160L3 is a Layer 3 daughter card designed to enhance the performance of the Cisco Nexus 5500 series switches, specifically the Nexus 5596 chassis. Built with scalability and high availability in mind, this module supports advanced routing capabilities, enabling dynamic Layer 3 routing protocols such as OSPF, BGP, and EIGRP. Its robust design features a 160 Gbps Layer 3 forwarding engine, ensuring efficient traffic management and seamless integration into complex data center environments. Ideal for high-density deployments, it allows users to consolidate Layer 2 and Layer 3 switching within a single platform.
This module is equipped with essential components including a dedicated CPU, memory, and forwarding engine to offload routing tasks from the supervisor module. It supports IPv4 and IPv6 unicast and multicast routing, along with VRF-lite for network segmentation. Designed to be hot-swappable, the N55-M160L3 enables minimal downtime during upgrades or replacements in live networks. When purchasing used, buyers should ensure the module is compatible with their existing Nexus 5500 series switch and verify that it has been tested for full functionality.
