3850 48TS Licenses
By default, This 3850 series switch is shipped with an IP Base base license. A whole range of Layer 2 and fundamental Layer 3 features, such as VLANs static routing Link Aggregation Control Protocol , Spanning Tree Protocol and Quality of Service capabilities, are included in the IP Base license.
To access extra features and functionality, the WS-C3850-48T-S allows alternative licenses in addition to the standard license, which can be bought individually. The following are some of the WS-C3850-48T-S optional licenses that are available:
- IP Services License: This license includes capabilities like Virtual Route Forwarding Lite along with other advanced Layer 3 routing protocols like Enhanced Interior Gateway Routing Protocol, Open Shortest Path First, and Border Gateway Protocol.
- The Advanced IP Services License is a license that has all the capabilities of the IP Services license plus additional support for advanced routing protocols including MP-BGP and Intermediate System-to-Intermediate System (IS-IS).
- Network Advantage License: This license offers sophisticated networking features including software-defined networking, automation, and analytics. It is a component of Cisco’s DNA licensing architecture.
- Another component of Cisco’s DNA licensing strategy is the DNA Essentials License, which offers the necessary DNA Center integration functionality for network automation and administration.
- All the features of the DNA Essentials license plus enhanced security, analytics, and assurance capabilities are included in the DNA Advantage license, which is the top tier of Cisco’s DNA licensing architecture.
It’s crucial to remember that license availability can change depending on the particular switch model and the licensing choices Cisco offers at the time of purchase.
Routing Protocols
Among its Layer 3 capabilities is the support for several routing protocols by the Cisco switch. The switch may execute dynamic routing thanks to these routing protocols, deciding how best to forward packets depending on the state of the network. The following are a few possible routing protocols that the WS-C3850-48T-S switch supports:
- Open Shortest Path First is a popular inner gateway protocol that determines the most direct route to a destination by taking into account the cost of the connection. Enterprise networks frequently use it, and it facilitates extensive installations.
- Another inside gateway protocol created by Cisco is called Enhanced inside Gateway Routing Protocol, or EIGRP. With characteristics including route summarization, quick convergence, and support for several network layer protocols, it is a distance vector method.
- Hop count is the statistic used by the Routing Information technique , a straightforward distance vector routing technique. It might still be supported for compatibility reasons even if it is less frequent in contemporary networks.
- Border Gateway Protocol : On the internet, autonomous systems are routed via BGP, an outer gateway protocol. Although Layer 3 switches such as the Catalyst 3850 series are usually found in routers at the periphery of networks, they can also handle BGP for certain use cases.
- Static Routing: Most Layer 3 switches offer static routing, despite it not being a dynamic routing protocol. Static route configuration is done by administrators manually, with each target network’s next hop specified. Smaller networks or those with particular routing needs frequently employ it.
Because of these routing protocols and its static routing capabilities, the Cisco WS-C3850-48T-S switch can be deployed in a variety of network contexts, such as campus networks, enterprise networks, and data center edge deployments. It can also provide complex routing capability.
