Description:

The Cisco WS-C4948-S Catalyst switch is used in enterprise and data center network infrastructures to provide high-performance Layer 3 Gigabit Ethernet switching for core and aggregation network deployments. Commonly installed in data centers, corporate backbone networks, and campus distribution layers where high throughput and low-latency switching are required. Network administrators and system integrators use this switch for network core deployment, infrastructure upgrades, and replacement of legacy Cisco Catalyst switching platforms.

Applications:

The Cisco WS-C4948-S switch is commonly deployed in enterprise and campus network environments where high-speed switching and Layer 3 routing are required at the distribution or aggregation layer. It is used in corporate data centers, financial institutions, telecommunications facilities, and large enterprise networks to connect access-layer switches, servers, and network infrastructure devices while supporting advanced routing, VLAN segmentation, and high-performance traffic handling across large network environments.
