More Information

The WS-C4900M is a switch model made by Cisco Systems. It belongs to the Cisco Catalyst 4900M series of switches.

This switch supports 10 Gigabit Ethernet (10GBase-X) on its 8 ports, meaning that it can transmit and receive data at a rate of up to 10 Gbps on each port. This makes it suitable for use in high-bandwidth environments such as data centers and high-performance computing networks.

The switch also supports fast Ethernet (100Mbps) on all its ports which is a feature that allows it to be compatible with older network devices that use this slower standard.

The model also features Cisco's advanced security and network management features, allowing for robust network monitoring and control. It's designed for high-performance, high-density applications and can be used in a variety of environments such as Campus, Data Center, Service Provider and Enterprise networks.

Features and Benefits

The WS-C4900M Cisco Catalyst 4900M is designed for high-performance, high-density applications and is capable of delivering a number of advanced performance features.

In terms of switching capacity, the switch can handle up to 320 Gbps of throughput, which allows it to process a large amount of data in a short amount of time.

It also supports non-blocking architecture which means that all of the ports on the switch can operate at their full capacity simultaneously, without any performance degradation. This allows for maximum flexibility in configuring the switch for different network requirements.

Additionally, The model has a high-performance ASIC that provides hardware-based forwarding and queuing, allowing for efficient and consistent performance.

Furthermore, it supports Jumbo Frame (up to 9216 bytes) which allows for larger packet sizes which can improve network performance in some cases.

Benefits of Layer 3 Switch

A Layer 3 switch is a type of network switch that can perform the functions of a traditional network router, in addition to the functions of a traditional network switch. This means that a Layer 3 switch can forward packets based on their IP address, in addition to forwarding them based on their MAC address (as a traditional switch would). This capability provides a number of benefits over traditional Layer 2 switches.

  • Routing: One of the most significant benefits of a Layer 3 switch is that it allows for routing at the switch level. This means that packets can be forwarded based on their IP address, rather than just their MAC address, providing a higher level of granularity and control over network traffic.
  • VLAN: Layer 3 switches can create virtual LANs (VLANs), which segment network traffic and improve security. VLANs can be created based on IP subnets, providing an additional level of segmentation beyond what is possible with traditional Layer 2 switches.
  • Quality of Service (QoS): Layer 3 switches can also prioritize network traffic based on IP address, providing more granular Quality of Service (QoS) capabilities. This allows for critical traffic, such as voice and video, to be given priority over less critical traffic.
  • Scalability: Layer 3 switches can also be used to create large, scalable networks. They can handle inter-VLAN routing and provide routing between different subnets.
  • Security: Layer 3 switches can provide enhanced security features such as access control lists (ACLs) and virtual private networks (VPNs) to protect against network threats.
