Link Aggregation

Link Aggregation

Link Aggregation is a method of grouping multiple physical ports on a network device into one logical link according to the IEEE 802.3ad‐2002 standard. Because Link Aggregation is standards based, it allows for automatic configuration with manual overrides (if applicable), and can operate on 10 Mbps, 100 Mbps, or 1000 Mbps Ethernet full duplex ports. Thus the network administrator can combine a group of five 100 Mbps ports into a logical link (trunk) that functions as a single 500 Mbps port. As long as the DFE modules agree on which ports are in the trunk, there are no problems with looping, and the Spanning Tree can treat this trunk as a single port.

In normal usage (and typical implementations) there is no need to enable/disable ports for Link Aggregation. The default values will result in the maximum number of aggregations possible. If the switch is placed in a configuration with its peers not running the protocol, no aggregations will be formed and the DFE modules will function normally (that is, Spanning Tree will block redundant paths).

For details about the commands involved with configuring the Link Aggregation function, refer to the Enterasys Matrix DFE‐Gold Series Configuration Guide.

Module Placement in a Matrix E7 Chassis

If you want to mix 6x1xxx, 6x2xxx, 6x3xxx, and 7H43xx‐xx series modules in the same Matrix E7 chassis, it is necessary to have a DFE module installed such as the 4G4285‐49, and also follow the module placement rules described in “DFE Module Placement and Installation Rules” on page 3‐3 to successfully bridge data traffic to some or all modules in the Matrix E7 chassis.

FTM Bridge Function and Optional NEM

The 4G4285‐49 DFE module does not support both the FTM bridging function and an optional network expansion module at the same time. With an optional network expansion module installed, the FTM bridging function is disabled. In either of these cases, all ports of the 4G4285‐49 remain active.

It is equipped to handle the increasing data traffic common in enterprise networks, facilitating enhanced throughput and reduced latency. This model features 48 Gigabit Ethernet ports, ideal for connecting a vast array of devices within a network, along with one or two 10 Gigabit SFP+ uplink ports, ensuring fast data transmission to other network segments.

On the other hand, the 4G4205-72 is specifically designed as a versatile access switch with 24 Gigabit Ethernet ports and an additional 4 SFP+ uplink ports. This configuration makes it perfect for connecting endpoints like computers, printers, and other network devices while also providing scalability for future expansion.

Both models leverage advanced technologies such as Virtual LAN (VLAN) support, which helps in segmenting network traffic for better performance and security. Quality of Service (QoS) features are integrated, allowing administrators to prioritize critical applications and ensure optimal performance during high traffic periods. Additionally, security protocols like Access Control Lists (ACLs) and port security measures safeguard the network against unauthorized access.

The Enterasys 4G4285-49 and 4G4205-72 also support advanced management capabilities. With intuitive web-based interfaces and support for SNMP (Simple Network Management Protocol), IT teams can efficiently monitor network performance and troubleshoot issues as they arise.

In terms of build quality, both models are designed for reliability, featuring robust chassis and components that withstand the rigors of a data center environment. Their energy-efficient designs also contribute to reduced operational costs, aligning with the growing demand for sustainable networking solutions.

In summary, Enterasys Networks' 4G4285-49 and 4G4205-72 models combine high performance, advanced networking technologies, and robust security features, making them ideal choices for enterprises looking to enhance their network infrastructure and manage increasing data demands effectively.
