If there is an upper-case X symbol after 4x digit – it means the platform has 8GB/8GB RAM/FLASH for SD-WAN advanced security support.Īre advanced security features? Intrusion To support Advanced SD-WAN security features, 8GB/8GB is required and some models, for example, 1111X-8P comes with these specs. The default RAM/Flash configuration for ISR 1000 family is 4GB/4GB. This family of fixed-port routers is constantly expanding with models of various WAN port types and the number of Ethernet switch ports. ISR 1000 routers provide connectivity for small branch offices. Cisco recommends using this option, as it simplifies the deployment and operation of SD-WAN. With cloud management, Cisco will host and maintain controllers, such as vManage, vBond, and vSmarts. On-premise management requires controller

There are benefits of using it related to license portability, which binds the license to an organization, as opposed to a specific device serial number.

DNA Advantage also delivers unlimited segmentation.
DNA Advantage provides all features of DNA Essentials and additional network and application assurance. It might beĭNA Essentials is entry-level subscription and supports up to 50 devices licensed with perpetual Network Essentials. Network Essentials and Network Advantage perpetual licenses. The devices are also licensed with either For example, with 100 Mbps license – you can have an Ethernet-based Internet service with 100 Mbps down and 100 Mbps up or 200Mbps of aggregate throughput.

Cisco licenses bandwidth as maximum for download AND upload, which means throughput for symmetrical traffic can be two times higher than the licensed value. SD-WAN bandwidth license tier and its available maximum per platform provide an additional indicator of what Cisco considers as expected performance in most scenarios. When local Internet breakout at a branch is enabled, demand for the encryption will go down. For example, in brownfield deployments where SD-WAN is replacing traditional WAN with centralized Internet access via the data center, encryption throughput is important. However, it is also important to know encryption throughput of the platform and evaluate requirements depending on the specific use case. The traffic can be analyed into the router itself, even if it’s uneasy: #show monitor capture buffer BUFFER dumpġ4:56:56.370 CEST : IPv4 LES CEF : Fa0/0 NoneĨ4387970: F3AC9CAF CA700F25 08004500 05DC5ABB s./Jp.%.E.Cisco publishes platform performance in datasheets as CEF IMIX traffic.
