SPA-2X1GE Use Case
Branch Office WAN Resilience with SPA-2X1GE EtherChannel Aggregation
In a regional retail branch, the Cisco SPA-2X1GE-Cisco 2-port Gigabit Ethernet Shared Port Adapter is installed on an ISR router to create a 2-port LACP EtherChannel uplink to the aggregation switch. This configuration delivers 2 Gbps of aggregated bandwidth, automatic link failover, and simplified network management. Outcome: continuous uptime, scalable performance, and streamlined operations.
Data Center Edge Segmentation for PCI Compliance
In a financial services data center, IT teams deploy the Cisco SPA-2X1GE-Cisco 2-port Gigabit Ethernet Shared Port Adapter on ISR 4000 routers to isolate DMZ and internal LAN traffic by assigning each gigabit port to separate security zones. This hardware-level segmentation accelerates firewall processing and simplifies compliance audits. Outcome: enhanced security posture, regulatory compliance, and reduced latency.
Campus Video Surveillance Backbone with High Availability
At a university campus, network engineers leverage the Cisco SPA-2X1GE-Cisco 2-port Gigabit Ethernet Shared Port Adapter on branch routers to bond two 1 Gbps ports, aggregating multiple IP camera streams over a resilient backbone. This ensures consistent throughput and seamless failover for real-time video monitoring. Outcome: uninterrupted surveillance, simplified scaling, and improved campus safety.
