Managing Ethernet MicroLAN Switches

NOTE

Some older repeater devices, and devices with older versions of Þrmware may include a slightly different deÞnition of station and trunk status: station ports are deÞned as those receiving packets from zero or one source addresses; trunk ports are deÞned as those receiving packets from two or more source addresses. If you have any questions about whether your device or Þrmware version falls into this older category, or if you would like information about upgrading your device Þrmware, contact the Cabletron Systems Global Call Center.

A sourceAddressTimeout trap is issued anytime a source address is aged out of the Source Address Table due to inactivity. The trapÕs interesting information includes the module and port index, and the source address that timed out.

PortTypeChanged traps are issued when a portÕs topology status changes from station to trunk, or vice versa. The interesting information includes the module and port index, and the portÕs new topology status.

A lockStatusChanged trap is generated when the ports in the hub are locked or unlocked using the Lock/Unlock Ports option on the Repeater menus; the interesting information is the new lock status.

PortSecurityViolation and portViolationReset traps are sent in response to changes related to port locking: if ports are locked, the portSecurityViolation trap indicates that a new source address has attempted access on one of the ports, and the ports are being shut down in response; the interesting information is the module and port index, and the violating address. PortViolationReset traps are sent when management intervention has re-enabled a port or ports previously disabled in response to a port security violation; the interesting information is module and port index.

Configuring Traps

The current status (enabled or disabled) for Link State, Segmentation, and Source Address traps will always be displayed in the port-level Trap Selection window. The repeater- and board-level windows will display current settings if they are uniform; where settings are not uniform at the selected level, the corresponding check box will be gray.

When you conÞgure traps, keep in mind the hierarchy of levels at which you are setting traps; for the Ethernet MicroLAN Switch, traps set at the repeater or board level will override current port-level settings for all ports on that repeater channel.

When you are setting repeater- or module-level traps, we recommend that you leave the

TIP gray ÒNo SETÓ status untouched (especially for Source Addressing Traps) unless you are sure you want to override port-level settings. With no incoming traps to inform you of a port security violation, you may have ports that are disabled on your device for no obvious reason.

2000 specifications

Cabletron Systems was a prominent company in the networking and communications industry during the late 20th century, and by the year 2000, it had established itself as a leader in providing high-performance networking solutions. The company was known for its innovative approach to network architecture and its commitment to delivering reliable products that enabled seamless connectivity in various environments.

One of the primary features of Cabletron Systems in 2000 was its advanced networking technologies, including Local Area Network (LAN) and Wide Area Network (WAN) solutions. The company specialized in developing multi-layer switches that could efficiently manage traffic and deliver high-speed data transfer. Their products were particularly popular in enterprise settings, where network performance and reliability were paramount.

Cabletron's solutions included a range of products, from Ethernet switches to routers, which were designed with scalability and flexibility in mind. This allowed businesses to adapt their networks to accommodate growth, without the need for a complete overhaul of their infrastructure. The company’s Integrated Networking Architecture (INA) was a significant innovation during this period, enabling efficient communication and management of diverse network resources.

Another major characteristic of Cabletron Systems was its commitment to interoperability. The company’s products were designed to be compatible with several industry standards, ensuring that organizations could easily integrate Cabletron solutions into their existing networks. This focus on compatibility helped to foster collaboration among different devices and systems, further enhancing network efficiency.

Security was also a key feature of Cabletron’s offerings in 2000. With growing concerns about data breaches and unauthorized access, the company incorporated advanced security measures into its products. These features included robust authentication protocols, encryption options, and secure management interfaces, which helped safeguard sensitive data during transmission.

Customer support and service were paramount to Cabletron Systems' business model. The company provided extensive resources, including training and technical support, to ensure that customers could maximize the potential of their networking solutions. This dedication to customer satisfaction contributed significantly to Cabletron’s reputation in the marketplace.

In summary, Cabletron Systems in 2000 emerged as a frontrunner in the networking industry, characterized by its innovative technologies, commitment to interoperability, emphasis on security, and strong customer support. Their products and solutions were designed to empower businesses, helping them achieve greater efficiency, scalability, and reliability in their network operations.
