Description
General Information about this Cisco WS-C4900M
Manufacturer: Cisco
Part Number or SKU# WS-C4900M
Product Line: Catalyst
Product Series: 4900
Product Type: Layer 3 Switch
The WS-C4900M Cisco Catalyst 4900M is a switch designed for enterprise and service provider environments. It has 10 Gigabit Ethernet (10GBase-X) ports and 8 Fast Ethernet ports. The switch is a member of the Cisco Catalyst 4900 series, which is known for its high performance, reliability, and security features. The switch supports advanced features such as Quality of Service (QoS), Access Control Lists (ACLs), and Virtual LANs (VLANs). Additionally, it supports power over Ethernet (PoE) which allow you to power devices over the Ethernet cables, reducing the need for dedicated power supplies. The 4900M series is also built to be serviceable, allowing for easy replacement of power supplies, fans and other components, reducing downtime.
High-Performance
The WS-C4900M Cisco Catalyst 4900M Switch is designed to provide high performance and density for use in data center and other high-bandwidth environments.
The switch has a forwarding rate of up to 140 Gbps, which means that it can handle a high amount of network traffic without experiencing significant delays or bottlenecks. Additionally, it has a switching capacity of 280 Gbps, which means that it can forward and process packets at a high rate without slowing down the network.
The switch also supports jumbo frames of up to 9216 bytes which can help to increase the amount of data that can be transported across the network in a single frame.
In terms of memory, the model Cisco Catalyst 4900M Switch has 4GB of DRAM and 4GB of flash memory which is sufficient for storing the Operating System and configuration files as well as providing buffer for frames.
Another performance feature that the switch includes is LACP (Link Aggregation Control Protocol) and EtherChannel support, which allows multiple physical links to be grouped together to form a single logical link. This increases the bandwidth available for a particular connection and improves network redundancy by providing multiple paths for data to flow.
Benefits of Layer 3 Switch
A Layer 3 switch is a type of switch that can perform routing functions in addition to switching. The benefits of using a Layer 3 switch include:
Increased network efficiency: By providing routing capabilities, a Layer 3 switch allows for more efficient use of network resources, as traffic can be directed to the most appropriate destination without the need for it to pass through a separate router.
Improved network scalability: A Layer 3 switch allows for the creation of multiple broadcast domains, which can help to reduce network congestion and improve scalability.
Enhanced security: A Layer 3 switch allows for the implementation of access control lists (ACLs) and virtual LANs (VLANs), which can be used to improve network security by controlling access to network resources.
Simplified network management: By incorporating routing functions into the switch, a Layer 3 switch can simplify network management and make it easier to add, modify, or remove network devices without disrupting network traffic.
Cost-effective: By eliminating the need for a separate router, a Layer 3 switch can save on costs and reduce the complexity of network design. It also can combine routing and switching features which save on equipment and cabling costs.
High-performance: Layer 3 switches usually have specialized hardware and software for routing, which means that they can perform routing functions faster than traditional routers, leading to increased network performance.
