Overview

The NH2025-10 is a robust switch platform, representing the next generation in switching technology. It boasts a combination of cutting-edge hardware architecture, a rich set of Virtual LAN (VLAN) options and advanced network management features.

Figure 1 - General View

The NH2025-10 contains a built-in SNMP agent running on the SNMP Processor Board. This allows each unit to be managed from a centralized management station through any SNMPcompliant NMS.

The SNMP agent software complies with the following standards:

RFC 1155 The Structure of Management Information (SMI) for TCP/IP Based Internets, May 1990

RFC 1212 The Management Information Base I (MIB I)

RFC 1213 The Management Information Base II (MIB II), March 1991.

RFC 1284 The Ethernet MIB

RFC 1286 The Bridge MIB

RFC 1757 The RMON MIB

The NH2025-10 also supports two NBase-Xyplex private MIBs: switch.mib and gswitch.mib.

The SNMP agent utilizes UDP/IP (RFC 768, RFC950, RFC1071 and RFC791) as OSI layers 3 and 4 protocols, ICMP (RFC792) and ARP (RFC826) to complete the UDP/IP protocol suite.

The UDP/IP stack implementation conforms to:

RFC 1122 Requirements for Internet hosts - communication layers.

RFC 1123 Requirements for Internet hosts - application and support.

The NH2025-10 may be managed by any SNMP Manager that conforms to the above standards. It may be fully managed by MegaVision, NBase-Xyplex’s multi-platform network management system. For more information on MegaVision, view our web site, or contact NBase-Xyplex for a data sheet.

The NH2025-10 implements an NBase-Xyplex Enterprise MIB and an NBase-Xyplex Product MIB that may be provided upon request.

Overview

Applications

A switch boosts network performance by segmenting a single large collision domain into smaller, separate collision domains. It also provides dedicated connections for heavily loaded networks using work stations and servers. In addition, the Full Duplex capability of Ethernet switches permits long distance connectivity for backbone applications or high throughput for high-performance dedicated servers. The NH2025-10 combines 10/100Mbps switched ports with a dport for accommodating an optional module.

The NH2025-10 switch can connect up to twenty-four 10/100Mbps ports and with a dport for accommodating an optional module Figure 2 illustrates various connection possibilities: Two NH2025-10 switches ,with Gigabit Ethernet uplink modules, located in different buildings can be connected via MM or SM fiber optic cable to a Gigabit Ethernet backbone. VLAN Tagging allows the creation of one logical VLAN across all switches. Additional connections include dedicated 10/100Mbps workgroup connections and 100Mbps dedicated servers.

Figure 2 - Typical Application Example

NOTE: The NH2025-10 does not count as a repeater. Each of the segments connected to the switch can support a full Ethernet network; there can be up to four 10Base-T repeaters/hubs between any NH2025-10 port and any station.

Network Management Systems

Network management functions greatly assist in monitoring and controlling the network. The NH2025-10 can be monitored and controlled through MegaVision or through a generic SNMPbased NMS. The connection to the NH2025-10 may be achieved through Ethernet.

To enable management of an NH2025-10 device, you must define the device and provide specific parameters to establish communication. The Describe window is used to define a new device or to change the parameters of a previously defined device.

The NH2025-10 can also be configured and managed through the Command Line Interface.

Installing and Setting Up the Unit

The NH2025-10 can operate as a stand-alone unit or in conjunction with any of NBase-Xyplex’s other Ethernet offerings. Switch management is through NBase-Xyplex MegaVision software, any SNMP-compatible NMS, or through the Command Line Interface (CLI).

Installing the Unit

This section outlines the installation and operation of the NH2025-10.

The NH2025-10 comes as a 19” rack-mountable unit. However, it can be placed either in a rack mount, using the enclosed rack-mount brackets, or on a secure flat surface. Ensure that the unit is within reach of the necessary connections (i.e. power outlet, Ethernet connections, and if the NH2025-10 is monitored through the serial port, a PC, UNIX workstation, or modem). The unit is powered by a wide-range power supply for either 110 or 220 VAC operation.

WARNING

Free airflow must be maintained in order to permit adequate cooling of the unit. All FAN holes MUST be unobstructed.

Rack Mounting

If rack-mounted units are installed in a closed or multi-rack assembly, they may require further evaluation by certification agencies. The following items must be considered when rack mounting a unit:

1.The ambient temperature within the rack may be greater than room ambient temperature, however the amount of airflow required for safe operation should not be compromised. The maximum temperature for this equipment is 50°C (122F). Consideration should be given to the maximum rated ambient temperature.

2.The rack should be stable, verify that stability is not inadvertently compromised during and after installation.

Installing and Setting Up the Unit

Grounding

Reliable grounding of this equipment must be maintained. Particular attention should be given to electrical connections when connecting to a power strip, rather than direct connections to the electrical outlet.

Connecting Ethernet Devices

For optimum performance, the Ethernet segments connected to the NH2025-10 must be configured carefully. Generally, the segments should be configured so that machines on a given port communicate primarily among themselves; that is, most traffic does not need to cross the switch. However, this is not the best configuration for certain situations.

Connecting Your Network

The cable connections to the 10/100BaseTX ports can be UTP or STP Category 3 and above, and cable length is limited to 100 meters on each port. STP cable carries a higher quality of signal and is less sensitive to environmental noise.

The RJ-45 ports of the switch are defined as MDI-X ports.

The 10/100BaseTX ports on the NH2025-10 are designed to be connected directly to a workstation, using a standard straight through patch cable. In order to cascade switches or connect a hub to the switch, a crossover cable must be used.

Getting Started

This section describes how to connect to the management port, log into the Command Line Interface, and set the unit’s IP Address.

Connecting to the Management Port

With the product we supply a management cable. You can use it to get access to the management port.

To configure the serial ports do the following items:

1.Connect the cable provided to the management port and communication interface (COM1 or COM2) of your PC.

2.Start Windows HyperTerminal and create a new connection with the property set to 9600 bit per second, 8 bits per character and no flow control.

3.Start HyperTerminal session and then type Enter to get the login prompt.

Logging Into the Command Line Interface

The Command Line Interface is protected with a login name and password.

To access the CLI the Network Administrator has to provide his name and a password.

Example

Please Login

username: don

password: (not echoed)

The factory default password is a null string. To log in just press the Enter key. Once you are logged into the CLI, you may change the password in order to avoid unauthorized access.

Setting the IP Address

To manage the MegaSwitch using an SNMP Network Management Application or to use the ping command to test the switch, it is necessary to assign an IP Address, a netmask and a broadcast address. The Network Administrator should assign the IP address in accordance with the existing IP addressing scheme.

Set the IP configuration using the set-ip-cfg command.

Example

SYS_console> set-ip-cfg 192.1.1.64 255.255.255.0 255.255.255.255

11

Getting Started

NOTE: If the switch has no IP Address, then the provided IP Configuration changes the running parameters as well as the NVRAM-based database. If the switch was already configured, the command only changes the NVRAM database. Therefore, to use the new parameters you should reset the Switch, using the warm-reset command.

You can also use the set-ip command to accomplish this. When you do, the mask and broadcast are automatically set to defaults according to the IP address class.

Example

SYS_console> set-ip 192.1.1.64

Verifying the Installation

After the installation is complete and the IP Address configured, use the Ping utility to test the connectivity.

The ping command sends an echo request to the host specified in the command line. For example, to test connectivity from the Switch to a workstation with an IP Address of 192.1.1.1, use the following command:

SYS_console> ping 192.1.1.1 100

Accessing the Command Line Interface Remotely

When the switch has an IP address, the administrative interface can be accessed remotely through Telnet. All commands work exactly as if the serial interface were being used. Please note that only one console session may be active at any given time. This means that after the first Telnet session is established, all other Telnet connections are refused until the current session is closed.

Using the Command Line Interface

This section describes how to use the Command Line Interface (CLI) to configure and manage the NH2025-10 switch.

Command Conventions

The following conventions are used within this guide to make understanding and using the CLI easier.

Command Items appearing in this typeface are to be typed as shown.

Italics Italicized items are variables and represent values. For example, <IPaddress> represents an IP address in dotted decimal notation as 123.1.2.3.

{ } | Items in { } and separated by | represent alternatives for the argument. For example:

get-comm {read|write|*}

means you can type one of the following:

get-comm read get-comm write

get-comm *

Command Line Help

The CLI provides command line help to ease in the entering of commands correctly. The following command line help is available:

Command parameter Help

Command group Help

Command wildcard Help

Command history

Getting Command Parameter Help

To get an explanation of a command’s parameters add a question mark (?) after the command name. For example:

SYS_console> ping ?

The unit displays the available parameters for the ping command:

ping IP traffic generator

[arg #0] destination IP address

[arg #1] number of packets to send or 0 for endless ping SYS_console> ping _

Note that the command is reprinted after the prompt. You can add the necessary parameters here. If a question mark is added after the first parameter, then the same explanation is provided, and the previous command, including the provided parameters, is redisplayed.

Using the Command Line Interface

Example

SYS_console> ping 129.1.1.7 ?

The unit displays the next level of parameters:

ping IP traffic generator

[arg #0] destination IP address

[arg #1] number of packets to send or 0 for endless ping SYS_console> ping 129.1.1.7

Getting Command Group Help

To find out the command groups that are available within the unit, enter a question mark at the CLI prompt. The CLI displays a list of all of the available command groups and a short explanation of each.

Example

SYS_telnet>?

 

Commands groups are:

 

-----------------------

console

Console related commands

system

System related commands

ip

IP related commands

snmp

SNMP related commands

switch-db

Switching Database related commands

vlan

Virtual LANS related commands

echannel

EtherChannel Commands

port-cfg

Port Configuration related commands

statistics

Switching Statistics related commands

sp-tree

Spanning Tree related commands

-----------------------------------------------------------------

use ! for previous cmd, ^U to clear line, ^W to clear previous word

-----------------------------------------------------------------

Entering a group name from this list displays a list of the commands under that group.

Using Command Wildcards

The CLI allows you to use the question mark <?> as a wildcard when you are unsure of a command. To use the wildcard, place the question mark immediately after the command you are looking for.

NOTE: You can type all or just a portion of the command followed by the question mark and the CLI returns all commands that start with that string.
