Cisco WS-C4900M Catalyst Switch – High-Performance Modular Core Switch

The Cisco WS-C4900M Catalyst Switch is a compact, modular, enterprise-class switch designed to deliver top-tier performance, scalability, and reliability in high-demand environments such as data centers and large-scale enterprise backbones. Part of the Cisco Catalyst 4900 Series, this switch is ideal for deployments that require non-blocking 10 Gigabit Ethernet connectivity, operational flexibility, and high availability.

With 320 Gbps switching capacity and a forwarding rate of up to 250 million packets per second (mpps), the WS-C4900M ensures ultra-low-latency traffic forwarding, suitable for bandwidth-intensive applications like virtualization, high-frequency trading, and cloud computing.

Key Advantages

• Modular Scalability
  The WS-C4900M offers a base configuration with 8 fixed 10 Gigabit Ethernet X2 ports and supports two additional half-width expansion slots, allowing a mix of Gigabit Ethernet and 10G modules. This flexibility makes it an adaptable core switch or high-capacity distribution switch.

• High Availability Architecture
  Equipped with dual hot-swappable power supplies (AC or DC) and a field-replaceable fan tray, the switch ensures continuous operation. Its hardware redundancy is well-suited for mission-critical networks that demand zero downtime.

• Multilayer Switching
  Supports advanced Layer 2 and Layer 3 switching, including IPv4 and IPv6 unicast routing, static and dynamic routing protocols (RIP, OSPF, BGP), and comprehensive QoS (Quality of Service) capabilities to prioritize voice, video, and critical data traffic.

• Robust Management Options
  The device includes a console port for out-of-band access and supports SNMP, Telnet, SSH, BOOTP, and TFTP for remote in-band management. It supports FAT file systems for local configuration storage and backup.

• Flexible Deployment Use Cases
  It can be used as:

  • A top-of-rack switch in a data center.

  • A collapsed core switch for small to mid-sized enterprises.

  • A distribution switch for large-scale campus LANs.
