Description: The WS-C3850-12X48U-S is a Cisco Catalyst 3850 Series switch. This series of switches is a stackable, multi-gigabit, and multigigabit Ethernet switch that provides full convergence between wired and wireless networks on a single platform.
The "12X48U" in the model number refers to the number of line card slots (12) and the number of uplink/stacking ports (48) that the switch has. The "S" at the end of the model number indicates that this is a standalone switch, as opposed to a switch that is part of a stack.
This switch has 48 Ethernet ports, which support both 10/100/1000Mbps and 10/100Mbps speeds. It also has two 10 Gbps uplink/stacking ports, which allow the switch to be stacked with other 3850 series switches to provide more ports and to form a single, virtual switch.
The switch also support for wireless connectivity as well as it can act as Wireless Lan Controller. This can be achieved by using the optional license for the wireless controller.
Performance and Reliability
The Cisco Catalyst 3850 series, of which the WS-C3850-12X48U-S is a part, is known for its high performance and reliability.
In terms of performance, the model can support up to 960 Gbps of switching capacity and up to 480 million packets per second (mpps) of forwarding rate. This makes it well-suited for deployments in high-bandwidth environments, such as those that require support for large numbers of users or high-definition video streaming.
Additionally, the switch supports advanced quality of service (QoS) features, such as differentiated services code point (DSCP) and Internet Group Management Protocol (IGMP) snooping, which allow you to prioritize different types of traffic to ensure that mission-critical applications receive the bandwidth they need.
In terms of reliability, the 3850 series supports StackWise-160 technology, which allows multiple switches to be connected together and managed as a single logical device. This makes it easier to manage large numbers of switch ports, and provides redundancy and failover capabilities.
This switch also supports redundancy with its Redundant Power System (RPS) which provides power backup for the switch, which allows for continuity of the operation of connected devices in case of a power outage. This feature also provides for redundancy in the power supply, which prevents the switch from shutting down in case of a power supply failure
Benefits of Layer 3 Switch
A Layer 3 switch is a type of switch that can perform routing functions in addition to traditional switching. This means that it can forward packets based on their destination IP address, just like a router. Some of the benefits of using a Layer 3 switch include:
Improved Performance: Because a Layer 3 switch can forward packets at the data link layer (Layer 2) and the network layer (Layer 3), it can often forward packets more efficiently than a traditional router. This can result in improved network performance and faster data transfer speeds.
Reduced Latency: By performing routing at the switch level, a Layer 3 switch can reduce the number of hops that a packet must take to reach its destination. This can result in lower latency, which can be beneficial for real-time applications such as voice and video.
Increased Security: A Layer 3 switch can be configured with access control lists (ACLs) to control access to the network. This can be used to restrict access to sensitive resources, such as servers and databases, and to help protect against network-based attacks.
VLANs Support: Layer 3 switch can route packets between different VLANs (Virtual LAN) without the need of external router, this capability save cost on hardware and reduce the number of hops for the packet.
