About the Cisco Catalyst 3750 WS-C3750X-12S-E Cisco Catalyst switch
With an 88 Gbps switching capacity and 65.5 Mpps forwarding rate, the Cisco Catalyst 3750 WS-C3750X-12S-E delivers line-rate performance for demanding enterprise environments. This managed Layer 3 stackable switch combines twelve 100/1000 Mbps SFP ports with one modular network module slot, accommodating either the C3KX-NM-10GT or C3KX-NM-1G uplink options to scale connectivity across distributed network architectures. Running Cisco IOS IP Services, the WS-C3750X-12S-E supports up to 4,094 VLANs, maintains a 16,000-entry MAC address table, and routes up to 24,000 unicast IPv4 routes using the router SDM template, making it a robust choice for multi-tier network designs.
Network engineers and IT procurement teams select this platform for its advanced feature density and operational flexibility. Cisco StackWise Plus technology enables up to nine switches to operate as a single logical unit with 64 Gbps stacking bandwidth, eliminating single points of failure while simplifying management. The device implements comprehensive security protocols including IEEE 802.1X, Cisco TrustSec, DHCP Snooping, Dynamic ARP Inspection, IP Source Guard, and Port Security. Hardware-based QoS with four egress queues per port, DSCP and CoS marking, and scheduling ensures predictable application performance. Full routing protocol support—OSPF, EIGRP, BGP, IS-IS, PBR, RIP v1/v2, and IPv6 routing—integrates seamlessly into complex backbone and distribution-layer topologies. Management options include CLI via SSH and Telnet, SNMPv1/v2c/v3, RSPAN/SPAN, and embedded RMON capabilities for real-time visibility.
