CISCO2811 Use Case
Cisco 2811 Router for Secure Branch VPN & Dynamic Routing
In a multi-site enterprise, the Cisco 2811 router (AC PWR, 2FE, 4 HWICs, IP Base) delivers encrypted site-to-site VPN tunnels, supports dynamic routing (EIGRP/OSPF) and QoS for converged voice/data. Dual WAN HWICs enable broadband/LTE failover. Outcome: Secure, resilient branch connectivity with 50% faster failover and centralized management through Cisco IOS.
Cisco 2811 Router as SMB VoIP Gateway with PVDM DSP
A regional SMB deploys the Cisco 2811 router’s 2 PVDMs and NME analog voice module to host 20 concurrent VoIP calls, SIP trunking and fax-over-IP. IP Base security features protect signaling and media. Outcome: 30% reduction in telephony costs, carrier-grade voice quality and a unified communications platform in a single chassis.
Cisco 2811 Router for Industrial IoT & Remote Automation
In a manufacturing plant, the Cisco 2811 router leverages its NME serial I/O and 4 HWIC slots for Modbus/DNP3 telemetry aggregation. IP Base services enable secure SSH, SNMPv3 monitoring and automated firmware updates. Outcome: Real-time equipment visibility, 25% faster incident response and streamlined IT/OT integration under one management interface.
