Cisco WS-C4948E-F Layer 3 Gigabit Ethernet Switch

The Cisco WS-C4948E-F is a Layer 3, 48-port Gigabit Ethernet switch in the Cisco Catalyst 4900 Series, designed for enterprise and data center infrastructures that require high-throughput routing with low latency. It delivers up to 320 Gbps switching capacity and 250 Mpps forwarding, with 48 × 10/100/1000 ports and 4 × SFP+ 10 Gb uplinks, running Cisco IOS 15.2 and supporting IEEE 802.1Q VLAN tagging. Routing features include static routing, RIP, OSPF, and BGP, while ACLs and security controls provide traffic protection; management is via CLI, SNMP, and Cisco network management tools. The switch is rack-mountable with dual AC power supplies, suitable for core or aggregation roles in corporate data centers and campus networks that connect access-layer switches, servers, and other network infrastructure gear; common replacements include Cisco Catalyst C9300-48T-A, C9500-48Y4C, and C9200L-48T-4X-E.
