The Cisco ISR C1111-4PLTEEA-DNA combines routing, a 4-port Gigabit Ethernet switch and an embedded LTE Advanced CAT6 modem in one small desktop chassis. It is built for small branches, retail stores, medical clinics and remote offices that need enterprise routing and security without a rack of separate equipment. The LTEEA designation marks the radio variant for North America and EMEAR. The LTELA version serves APAC and LATAM. On the WAN side there are two Gigabit ports: one copper and one copper/SFP combo for fiber handoffs. The LTE modem adds a cellular path for primary access or failover. In autonomous mode, Cisco rates the router at up to 1600 Mbps IPv4 forwarding and up to 500 Mbps IPsec (512B). In SD-WAN mode it delivers up to 450 Mbps IPsec and scales to 200 overlay tunnels. The platform ships with 4 GB of DRAM and 4 GB of flash. Scalability figures include 280K IPv4 routes, 100K NAT sessions and 1K VRFs. You can run traditional Cisco IOS XE (minimum release 16.6.1) and manage it centrally with Cisco DNA Center. Alternatively, run IOS XE SD-WAN under vManage, either cloud-hosted or on-premises. IP Base is the default licence. Application Experience, Security, HSEC and IPsec Performance licences add MPLS, AVC, zone-based firewall, DMVPN, FlexVPN and GETVPN. The front and rear panels include a Micro-USB/RJ-45 console port and a Type A USB 3.0 port. Optional PoE is available with the 115W ISR-1100-POE2 power supply, which powers 2 PoE or 1 PoE+ device from the LAN ports. The router draws a maximum of 22.7W and weighs 4.5 lb. An optional ACS-1100-RM-19 kit mounts it in a 19-inch rack.
