Cisco WS-C4948-S 48-Port Layer 3 Ethernet Switch

The Cisco WS-C4948-S is a 48-port Layer 3 Ethernet switch designed for high-throughput core and aggregation deployments in data centers and enterprise networks. It provides 48 × 10/100/1000 Gigabit Ethernet ports and 4 × SFP Gigabit uplinks, delivering up to 136 Gbps of switching capacity and up to 101 Mpps forwarding. Running the IP Base feature set, it supports IEEE 802.1Q VLAN tagging and Layer 3 routing with static routing, RIP, and OSPF for distribution or aggregation roles. Management is via CLI and SNMP with Cisco management tools, and security features include ACLs, port security, and network authentication. The unit uses a single internal AC power supply in a rack-mountable chassis and is commonly deployed in data centers, corporate backbone networks, and campus distribution, where it can connect access-layer switches, servers, and other network infrastructure devices while upgrading infrastructure or replacing legacy Catalyst platforms.
