Switch to Edge-corE

June 2014 IT infrastructure

A switch is a switch is a switch, right? Think there is nothing new to learn about switches?

What is a Layer 2 switch? Switching on Layer 2 enables a switch to identify the mac address of any packet. When nodes are connected to a switch, a table is drawn up of mac addresses and the ports they are connected to. Using this table, packets are only sent to the port associated with the intended recipient.

What is a Layer 3 switch? Moving one step higher on the beloved OSI model, a Layer 3 switch can understand the IP address of a packet.

What is a managed switch? Depending on the switch you choose, your switch now either has the ability to understand mac addresses or IP addresses, what can I do with this information? A managed switch will allow you to make decisions based on either a mac address (Layer 2) or an IP address (Layer 3). You can now separate networks (VLANs and subnets), prioritise traffic, monitor devices using the SNMP protocol and aggregate ports to increase throughput. The critical difference between Layer 2 and Layer 3 switches are that Layer 2 switches can create VLANs (virtual local area network) or subnets, but cannot enable communication between them. A Layer 3 switch can create VLANs and subnets and enable communication between them.

Network designers employ subnets and VLANs as a way to partition networks into logical or physical segments for greater ease of administration. When these are properly implemented, both the performance and security of networks can be improved.

What is a VLAN? Managed switches allow you to allocate specific ports to selected virtual networks, essentially creating two separate networks on the same switch.

Fully managed switches

The Edge-corE 4210 and 4110 series provides 24 and 48 port switches with 4x SFP slots for Gigabit Fibre or Ethernet uplinks. Perfect for fibre to Ethernet breakout solutions when carrying out IP video and Voice-over-IP installations that also require quality of service and intuitive management features.

The Edge-corE ECS4510 series is a compact but high-performance Gigabit Ethernet Layer 2+ switch featuring 24 or 48 gigabit ports, 2 10G SFP+ ports, and one 10G dual port expansion slot. This switch is ideal for high-performance server aggregations, such as enterprise data centres, where it can connect high-end network-attached files servers over fibre ports. It can also be deployed as a backbone upgrade, or to provide Gigabit to power users. This switch is a cost-effective solution that brings continuous availability, enhanced security and advanced Quality of Service (QoS) to any network, while maintaining simplicity of management.

Layer 3 switches offering stacking ability, optional 10G SFP+ (10 km) or 10G XFP (80 km). The Edge-corE ECS4610 series includes two stackable Gigabit Ethernet routing switches with a choice of 24 or 48 Gigabit ports, four combination Gigabit Ethernet SFP slots, two optional 10 Gigabit Ethernet slots for SFP+ (10 km) or XFP (80 km), and two stacking ports on the rear panel. The ECS4610 Series is ideal for service provider aggregation, enterprise wiring closets, data centre aggregation, and network core deployment. It provides high performance, resilient stacking, wire-speed L2 switching and L3 routing, comprehensive QoS, and advanced security to deliver the scalability and resiliency to increase your company’s productivity while reducing operation costs.
