Compact Enterprise Branch Router
The Cisco C1111-4P provides a flexible routing platform for organizations that require secure WAN connectivity and integrated LAN switching in a compact chassis. It is part of the Cisco ISR 1100 Series and is designed for branch offices, small businesses, retail locations, remote offices and managed service environments.
The router provides four integrated Gigabit Ethernet LAN ports and two Gigabit Ethernet WAN interfaces. One WAN interface combines RJ-45 copper and SFP fiber connectivity, while the second WAN interface provides RJ-45 Gigabit Ethernet connectivity. This configuration allows the C1111-4P to support flexible WAN deployment scenarios.

4-Port Gigabit LAN Connectivity
The Cisco C1111-4P includes 4 integrated Gigabit Ethernet LAN ports for connecting computers, IP phones, printers, wireless access points, surveillance devices and other network equipment.
Gigabit Ethernet LAN
Four integrated copper Gigabit Ethernet LAN ports provide high-speed local network connectivity for branch-office devices and users.
Flexible WAN Connectivity
Two Gigabit Ethernet WAN interfaces provide dual-WAN connectivity, including one RJ-45/SFP combo interface for copper or fiber deployment.
Dual Gigabit WAN Interfaces
The C1111-4P provides two integrated Gigabit Ethernet WAN interfaces for enterprise branch connectivity. The first WAN interface is a RJ-45/SFP combo port, allowing organizations to select copper or fiber connectivity according to their network infrastructure. The second WAN interface is a dedicated RJ-45 Gigabit Ethernet port.
- 2 × integrated Gigabit Ethernet WAN interfaces
- 1 × RJ-45/SFP combo WAN interface
- 1 × RJ-45 Gigabit Ethernet WAN interface
- Supports flexible branch WAN architectures
- Suitable for primary and secondary WAN connectivity

Optional PoE and PoE+ Support
The Cisco C1111-4P can be configured with optional Power over Ethernet functionality. The platform supports up to 2 PoE ports or 1 PoE+ port, allowing compatible devices to receive power and network connectivity through Ethernet cabling.
PoE
Optional 2-port PoE support can provide power to compatible network devices such as IP phones and access points.
PoE+
Optional PoE+ capability provides higher power delivery for supported network devices requiring additional power.

Cisco IOS XE Software Platform
The Cisco C1111-4P operates with Cisco IOS XE, providing a modern software platform for enterprise routing, security, automation and network management. IOS XE supports advanced enterprise networking capabilities required for branch-office environments.
The platform can be integrated into Cisco-managed network environments and supports software-defined networking and SD-WAN capabilities, helping organizations simplify branch connectivity and centralized network operations.
Integrated Security and SD-WAN Capabilities
Security is an important part of the Cisco ISR 1100 Series architecture. The C1111-4P is designed to combine routing, security and WAN connectivity within a single branch platform.
- Integrated enterprise routing functionality
- IPsec VPN capabilities
- SD-WAN support through Cisco IOS XE
- Access Control List support
- Network Address Translation support
- Virtual Routing and Forwarding support
- Centralized branch network management capabilities

Performance and Routing Capacity
The C1111-4P is engineered for branch environments where reliable routing and secure WAN connectivity are essential. Cisco documentation specifies a maximum encrypted throughput of up to 679 Mbps for the 111x platform in single-tunnel IMIX testing.
Under Cisco's 17.9 performance measurements, the C111x-4P provides up to 1,889 Mbps SD-WAN IPsec throughput at 1400-byte packet size and up to 338 Mbps SD-WAN IPsec throughput with IMIX. Autonomous-mode measurements include up to 1,372 Mbps IPv4 forwarding throughput with IMIX.

4GB Memory and Flash Storage
The standard C1111-4P configuration includes 4GB DRAM and 4GB flash memory. The 4GB memory configuration provides the resources required for standard routing, security and branch networking workloads.
It is important to distinguish the standard C1111-4P from Cisco X-series models. Cisco identifies the X designation as the configuration with 8GB DRAM and 8GB flash for application-hosting capabilities.
Management and USB Connectivity
The Cisco C1111-4P includes console connectivity for configuration and troubleshooting, along with a USB 3.0 Type-A port for convenient storage and operational requirements.
Console Connectivity
The platform provides console access through its integrated RJ-45/Micro-USB console capability for device configuration and troubleshooting.
USB 3.0
The integrated Type-A USB 3.0 interface can be used for convenient storage and supported operational tasks.
