C1111-4P - Cisco ISR 1111 Router

Cisco C1111-4P — ISR 1111 Series 4-Port Integrated Services Router

What it is

C1111-4P is a Cisco ISR 1111 Series branch and edge router designed for small offices, retail sites, and distributed enterprise networks.
It combines 4 Gigabit Ethernet ports, integrated routing, security features, and flexible WAN connectivity in a compact, secure platform optimized for SD-WAN, VPN, and modern application traffic at small-to-medium locations.

Why buyers pick C1111-4P (plain English)

Compact, secure branch edge
Delivers essential routing and security capabilities for remote offices without the size and complexity of larger routers.

Flexible WAN options
Supports multiple WAN link types (broadband, MPLS, LTE with optional modules), letting you design resilient branch connectivity with failover and load balancing.

Integrated security
Includes stateful firewall, NAT, IPSec VPN, and QoS — protecting branch traffic and enabling secure site-to-site or remote access connectivity.

Cisco IOS XE platform
Runs the enterprise-grade IOS XE operating system with consistent CLI, programmability, and support for SD-WAN, which simplifies policy and service delivery across distributed sites.

Efficient hardware
Four 1 GbE ports provide LAN/WAN connectivity without extra switches at small locations; compact form factor saves space and power.
