WS-X4993 Use Case
Enterprise Wiring Closet Aggregation with Catalyst 4948E (WS-X4993)
In a large corporate office, the WS-X4993 module in the Catalyst 4948E delivers 48x Fast Ethernet user ports plus dual SFP uplinks to the distribution layer. By implementing VLAN segmentation per department and link aggregation on uplinks, IT teams simplify cabling, boost resiliency, and support up to 800 endpoints in a single wiring closet. Outcome: streamlined network management, higher availability, and scalable growth in a compact footprint.
Data Center Edge Connectivity for Rack Servers with WS-X4993 Catalyst 4948E
Within a server-dense rack, the Catalyst 4948E’s WS-X4993 module provides 48x 10/100 ports for direct server attachment and two hot-swappable SFP uplinks to aggregation switches. Leveraging LACP for non-blocking throughput and granular QoS for virtualization traffic ensures predictable performance under heavy load. Outcome: low-latency server-to-core communication, enhanced redundancy, and consistent application performance.
Secure Branch Office Access with 802.1X Enforcement on WS-X4993
A mid-sized branch office uses the WS-X4993 in the Catalyst 4948E chassis to enforce IEEE 802.1X authentication across 48 workstations. Integrated with Cisco ISE for role-based access control, the solution applies guest VLAN isolation, static MAC filtering, and port security to block unauthorized devices. Outcome: robust endpoint security, compliance with corporate policies, and reduced risk of internal threats without sacrificing user productivity.
