Chapter 5: Local Management

The following briefly defines each selectable item of the Device Specific Configuration Menu screen:

SYSTEM RESOURCES

The System Resources screen displays the amount of FLASH memory, DRAM and NVRAM installed, indicates the amount of available memory and provides information on 2E4X-27R operation. For details, refer to Section 5.13.

HIGH SPEED INTERFACE CONFIGURATION

The High Speed Interface Configuration screen provides access to the Fast Ethernet Interfaces screen and the HSIM Setup screen. For details, refer to Section 5.14.

FLASH DOWNLOAD

The FLASH Download screen allows the user to force the 2E4X-27R to download a new image file from a TFTP server to its FLASH memory. For details, refer to Section 5.16.

PORT REDIRECT FUNCTION

The Port Redirect Function screen allows the user to redirect traffic from one or multiple switch ports to a specific destination switch port. For details, refer to Section 5.17.

BROADCAST SUPPRESSION

The Broadcast Suppression screen allows the user to set a desired limit of received broadcast frames that are forwarded per port per second. For details, refer to Section 5.18.

802.1Q VLAN Configuration

This menu item will only display if the 2E4X-27R has been configured to operate as an IEEE 802.1Q switch as described in Section 5.11.1, Setting the Operation Mode. When selected, this menu item opens the VLAN Main Menu screen. For details about the VLAN Local Management screens and how to use them to configure VLANs in the 2E4X-27R, refer to the Cabletron Systems Port Based VLAN User’s Guide.

2E49-27R, 2E48-27R specifications

Cabletron Systems 2E48-27R and 2E49-27R are powerful network switching devices that are designed to enhance the performance and reliability of network infrastructures. These devices play a critical role in ensuring seamless data transmission, making them essential for both enterprise environments and larger network setups.

One of the standout features of the Cabletron Systems 2E48-27R and 2E49-27R is their high-density design. The 2E48-27R model is equipped with 48 Ethernet ports, while the 2E49-27R includes 48 Ethernet ports along with an additional uplink capability that enhances flexibility in network connections. This high port density allows organizations to efficiently manage and connect multiple devices without taking up excessive space, making the devices ideal for environments where space is a premium.

Both models incorporate advanced switching technologies that support high throughput and low latency. This ensures that data packets are processed quickly and accurately, providing users with consistent performance and minimal delays. They also support various networking standards, including IEEE 802.3, ensuring compatibility with a wide range of devices and systems.

Another key characteristic of the 2E48-27R and 2E49-27R is their support for VLANs (Virtual Local Area Networks). This functionality allows network administrators to segment network traffic for better organization and security. By isolating different types of traffic, VLANs help to improve performance and reduce congestion, making it easier to manage network resources effectively.

In terms of management capabilities, both models offer robust features through SNMP (Simple Network Management Protocol). This allows for centralized network monitoring and management, giving administrators the tools they need to troubleshoot issues quickly and maintain optimal network performance. Additionally, the devices support easy upgrades and configuration changes, which can be crucial for adapting to evolving networking needs.

Security is another paramount feature included in the Cabletron Systems 2E48-27R and 2E49-27R. They offer access control lists (ACLs) and other security measures that help protect the network from unauthorized access and potential threats.

In summary, Cabletron Systems 2E48-27R and 2E49-27R are robust networking devices that combine high-density port configurations, advanced switching technologies, VLAN support, and comprehensive management capabilities. These features make them well-suited for high-demand network environments, ensuring efficient and secure data transmission while maximizing organizational performance.
