3.Use the arrow keys to highlight the SAVE command field at the bottom of the screen and then press ENTER. The message “SAVED OK” displays.

Conﬁguring the UDP Broadcast Redirector

To locate a server that can provide a particular network service, many IP hosts rely on the use of LAN broadcasts to send UDP service requests. The UDP port number contained in the broadcast request packet identiﬁes the service being requested. Table 23 shows the port numbers and their corresponding requested services.

	Table 23 UDP Port Numbers

UDP Port #	UDP Services


37	Time

42	Host Name Server

53	Domain Name Server

65	TACACS-Database Service

67	Bootstrap Protocol/Dynamic Host Control Protocol Server

68	Bootstrap Protocol/Dynamic Host Control Protocol Client

69	Trivial File Transfer

137	NETBIOS Name Server

138	NETBIOS Datagram Server

111	Sunrpc (NIS)

The UDP Broadcast Redirector enables you to conﬁgure any Routing Services enabled device to forward the UDP packets that it receives as LAN broadcasts, directly to the appropriate server. UDP service requests that are sent as LAN broadcasts by clients of applications such as Host Name, Domain Name, and Bootstrap servers, can be redirected to any server on any network segment.

To conﬁgure the UDP Broadcast Redirector, complete the following steps:

1.Use the arrow keys to highlight the UDP Port option under System Level Setup.

2.ENTER the UDP port number of the UDP service request packets that you want to redirect (refer to Table 23) and then press ENTER.

CSX400-DC, CSX400 specifications

Cabletron Systems was a leading developer of networking solutions, and its CSX400 and CSX200 series of high-performance switches represent some of the key innovations in the field of enterprise networking during their time. Both models were geared towards enhancing network reliability, efficiency, and speed, particularly in environments where heavy data traffic and complex networking demands were prevalent.

The CSX400, designed for larger enterprises, boasts a robust architecture capable of handling significant throughput. One of its standout features is its stackable design, allowing multiple switches to be interconnected and managed seamlessly as a single unit. This scalability provides organizations with the flexibility to expand their networks without significant infrastructure overhauls. The CSX400 supports various Ethernet standards, including 10/100 Ethernet and Gigabit Ethernet, positioning it to effectively manage both legacy and modern networking requirements.

In addition to its scalability, the CSX400 is distinguished by its advanced Layer 2 and Layer 3 routing capabilities. This dual-layer functionality enables efficient data handling and is instrumental in managing traffic between different network segments. Moreover, the switch incorporates features like VLAN (Virtual Local Area Network) support and Quality of Service (QoS) prioritization, allowing for enhanced performance of critical applications and streamlined bandwidth allocation.

On the other hand, the CSX200 series is tailored for smaller enterprises or branch offices needing a reliable yet efficient networking solution. Despite its compact design, the CSX200 is equipped with essential features that promote effective network management and security. It offers a simplified management interface, making it user-friendly for network administrators. The switch also provides essential access control measures, employing technologies like IEEE 802.1X for network access security.

Both the CSX400 and CSX200 prioritize performance through the incorporation of advanced switching technologies. They support features such as Spanning Tree Protocol (STP), enabling loop-free topologies and enhanced network resilience. These attributes are particularly crucial in dynamic networking environments where downtime can have significant repercussions on business operations.

Overall, Cabletron Systems' CSX400 and CSX200 series represent a blend of scalability, advanced routing capabilities, and user-friendly management, making them vital assets for organizations looking to optimize their network infrastructure during a period of rapid technological evolution. With their rich feature sets and unwavering performance, these switches helped pave the way for modern networking solutions that cater to diverse enterprise needs.
