About the Cisco Catalyst 4500 WS-C4900M Cisco Catalyst switch
Dual redundant power supply support ensures continuous uptime for this enterprise-class Cisco Catalyst 4500 managed switch, making it ideal for mission-critical data center deployments where power resilience is non-negotiable. The WS-C4900M delivers carrier-grade reliability with a 2U rack-mountable form factor that integrates seamlessly into standard infrastructure footprints while providing robust Layer 2/3 switching capabilities.
This Cisco Catalyst 4900M switch targets network architects and IT infrastructure teams who demand high-performance core and distribution layer connectivity. With 8 fixed 10GbE SFP+ ports, a switching capacity of 256 Gbps, and a forwarding rate of 190 Mpps, it handles demanding east-west traffic patterns in virtualized and cloud-native environments. The device supports up to 4,094 VLANs, a 55,000 MAC address table, and jumbo frames up to 9,216 bytes, enabling sophisticated network segmentation and large-payload transport. Hardware-based QoS with 8 queues per port delivers deterministic traffic prioritization, while hardware-enforced IPv4 and IPv6 ACLs provide granular security policy enforcement. Advanced routing protocols—including Static, OSPF, EIGRP, BGP, and RIP (IOS feature set dependent)—support complex multi-path topologies. Spanning Tree variants (802.1D STP, 802.1w RSTP, 802.1s MSTP) and IEEE 802.3ad LACP link aggregation round out the feature set, and the single expansion module slot provides future flexibility. Running Cisco IOS, the WS-C4900M integrates with existing management ecosystems and operational workflows.
Organizations deploying high-availability networks across multi-tenant or geographically distributed sites rely on switches like this to meet stringent uptime and performance SLAs.
