Product Description

ISR 1100 4P Dual GE SFP Router

Memory (default and maximum)


Only C1111X-8P,C1121X-8P,C1126X,C1127X, C1161X models have 8GB DRAM

•Flash: 4 GB

Only C1111X-8P,C1121X-8P,C1126X,C1127X, C1161X models have 8GB Flash


•Micro USB console (Type A).


Micro-USB port (reserved)

•Micro-USB port to support remote LTE diagnostics and monitoring tools (Qualcomm CAIT and Spirent UDM) (USB 3.0).

WLAN interfaces

•Multiuser Multiple-Input Multiple-Output (MU-MIMO) allows transmission of data to multiple 802.11ac Wave 2capable clients simultaneously to improve the client experience. Prior to MU-MIMO, 802.11n and

•802.11ac Wave 1 access points could transmit data to only one client at a time, typically referred to as Single-User MIMO (SU-MIMO).

•802.11ac Wave 2 with 2x2:2 MIMO technology uses two spatial streams when operating in SU-MIMO or MU-MIMO mode, offering 867-Mbps rates for more capacity and reliability than competing access points.

•Flexible deployment through the Mobility Express solution is ideal for small to medium-sized deployments. Easy setup allows the 1000 Series (similar to 1815i) to be deployed on networks without a physical controller.

•For more information, view the Cisco Aironet 1815i Access Point Data Sheet.

Maximum clients
