Introduction 1-1

Overview

The 2H258-17R is used to connect individual high-bandwidth user devices, such as workstations, or to provide a central switching point for multiple 100-Mbps Fast Ethernet segments. The optional HSIMs provide high speed uplinks to networking technologies such as Fast Ethernet, Gigabit Ethernet, Fiber Distributed Data Interface (FDDI), Wide Area Network (WAN), and Asynchronous Transfer Mode (ATM). Some HSIMs can provide additional Fast Ethernet ports in varying media types. The optional VHSIMs provide very high speed uplinks to networking technologies such as Gigabit Ethernet and ATM.

The 2H258-17R ports can be configured to control frame traffic in several ways, including prioritizing traffic flow according to protocol type. The 2H258-17R can also be configured to establish Virtual Local Area Networks (VLANs) and control the flow of frames associated with each VLAN according to priority and Ether type. Detailed information about VLANs is provided in the SmartSwitch Series 2E253, 2H252, 2H253, and 2H258 Local Management User’s Guide.

The 2H258-17R may be used as a tabletop unit or can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2H258-17R has two power supplies. The power supplies load share 50% (+/-5%) of the power required by the device. If one power supply fails, the remaining power supply assumes the entire load of the device without interruption to network traffic. Each power supply module supports its own ac input connection, which enables each power supply to be connected to a different ac power circuit.

1.1.1 Connectivity

The 2H258-17R connects to Ethernet networks or workstations through the 16 fiber-optic multimode MT-RJ ports on the front panel. These ports are in full compliance with the optical performance requirements of 100BASE-FX version of IEEE 802.3u.The ports support multimode fiber optic cables with 1300-nm surface emitting InGaAsP LEDs at lengths up to 2 kilometers for 100 Mbps.

The device also has a slot for an optional HSIM or VHSIM to provide additional connectivity to various networking technologies.

1.1.2 Runtime IP Address Discovery

This feature enables the 2H258-17R device to automatically accept an IP address from a Boot Strap Protocol (BootP) server on the network without requiring a user to enter an IP address through Local Management.

When the device is connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the device for an IP address. If one has not yet been assigned (device IP address set to 0.0.0.0), RAD checks to see if any of the device interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a BootP server on the network.

1-2 Introduction

Overview

The RAD requests start at an interval of 1 per second. The interval then doubles after every transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300 seconds. The RAD requests continue until an IP address is received from a RARP or BootP server, or an IP address is entered using Local Management.

NOTE: The 2H258-17R will reboot after RAD is successful.

1.1.3 Full Duplex Switched Ethernet

Each switched Fast Ethernet port on the 2H258-17R supports 100 Mbps operation, and can operate in Full Duplex Switched Ethernet (FDSE) mode. FDSE enables each port to provide up to 200 Mbps of bandwidth to connected devices that support FDSE.

1.1.4 SmartTrunk

Traditional 802.1D Spanning Tree Bridges only allow one active data path between any two switches; all other parallel data paths are in Standby or Blocking mode. If one interface or path should fail, then the other interface automatically comes out of Blocking mode and forwards all of the traffic. This is fine for redundancy purposes. However, it is not the most efficient use of resources.

SmartTrunk, also referred to as SmartTrunking, is Enterasys Networks’ terminology for load balancing or load sharing. SmartTrunk provides the ability to take full advantage of the network’s redundant bandwidth. SmartTrunk divides network traffic across multiple ports in parallel to provide additional throughput. The SmartTrunk application can be used with any of Enterasys Networks’ switch modules (except ATM modules).

For more information about SmartTrunk and how to configure it the SmartSwitch device, refer to the Enterasys Networks SmartTrunk User’s Guide.

1.1.5 Remote Monitoring (RMON)

The 2H258-17R supports all nine Ethernet RMON groups. The Statistics, Alarms, Events and History groups are enabled on all ports by default.

Enterasys Networks RMON Actions is a vendor-specific extension of RMON and provides the ability to set an “Action” on any SNMP MIB variable. The Action can be triggered by any RMON Event and/or Alarm. An example of an Action would be to turn off a MIB-2 interface if a broadcast threshold is crossed.

Introduction 1-3

Overview

1.1.6 Broadcast Suppression

Broadcast Suppression enables a user to set a desired limit of receive broadcast frames per port/per second to be forwarded out the other ports on the device. Any broadcast frames above this specified limit are dropped. In the event that broadcast frames are being suppressed, multicast and unicast frames continue to be switched.

1.1.7 Port/VLAN Redirect Functions

The port redirect function, also referred to as “Port Mirroring,” is a troubleshooting tool used to map traffic from a single source port to a single destination port within the device. This feature allows frames, including those with errors, to be copied and sent to an analyzer or RMON probe. The analyzer or RMON probe will see the data as if it were directly connected to the LAN segment of the source port.

The VLAN redirect function is similar to the port redirect function except that the frames received by the device are redirected to a designated destination port according to the VLAN classification of the frames received. Multiple VLANs can be directed to the same destination port. The VLAN redirect function is only supported when the device is operating as an 802.1Q switch.

1.1.8 Traffic Rate Limiting

The Rate Limiting feature enables the SmartSwitch device to have control over traffic rates on a per-port, per-priority basis. The network administrator can configure a rate limit (from 100 kbps to 1 Gbps) for a given port with an associated list of IEEE 802.1p priorities (which can include one, some, or all of the eight priority levels defined in 802.1p). Each rate limit is specified as an inbound or an outbound limit. The combined rate of all traffic on the port that matches the listed priorities cannot exceed the programmed limit. If the rate exceeds the defined limit, frames are dropped until the rate falls below the limit.

Administrators can configure up to four rate limit rules per port; however, each rule must not include conflicting 802.1p priority values. In order to control traffic inbound and outbound on the same port, two rate limit rules must be configured (one inbound and one outbound). Since the rate limiting operation occurs after the processing of the multi-layer classification rules, the two features can be combined to provide application-aware rate limiting.

NOTE: This rate limiting function is not supported on ports connected to SmartTrunk ports.

Overview

1.1.9 Flow Control

Flow control is a method of managing the flow of frames between two devices. It ensures that a transmitting device does not overwhelm a receiving device with data. This is accomplished by the transmitting device pausing its transmission while the receiving device processes the frames already received.

The 2H258-17R supports the following two types of flow control:

• Frame based 802.3x

• Back pressure

Frame based 802.3x flow control is supported on all Ethernet ports operating in the full duplex mode. Flow control can be enabled or disabled on a port-by-port basis.

Back pressure flow control is supported on all Ethernet ports operating in the standard mode of operation. Flow control can be enabled or disabled on a port-by-port basis.

1.1.10 GARP Switch Operation

Some or all ports on the switch may be activated to operate under the Generic Attribute Registration Protocol (GARP) applications, GARP VLAN Registration Protocol (GVRP) and/or GARP Multicast Registration Protocol (GMRP).

GARP is a protocol, or set of rules, that outlines a mechanism for propagating the port state and/or user information throughout a bridged LAN to keep track of users and VLANs on the network fabric. MAC bridges and end users alike can take part in the registration and de-registration of GARP attributes such as VLAN and multicast group membership. For more details on how GVRP and GMRP handle frames under GARP, and how to configure the switch ports to take advantage of this operation, refer to the SmartSwitch Series 2E253, 2H252, 2H253, and 2H258 Local Management User’s Guide.

1.1.11 802.1 Port Priority

The 802.1 port priority is used to assign a default priority to the frames received without priority information in their tag header, map prioritized frames to the appropriate transmit queues, and prioritize frames according to protocol type. The 802.1 port priority is part of the IEEE 802.1D standard.

3.4 CONNECTING TO THE NETWORK

This section provides the procedures for connecting fiber optic segments from the network or other devices to the 2H258-17R.

NOTE: If the 2H258-17R is being installed in a network using SmartTrunking, there are rules concerning the network cable and port configurations that must be followed for SmartTrunking to operate properly. Before connecting the cables, refer to the SmartTrunk User’s Guide for the configuration information.

Ports 1 through 16 on the 2H258-17R have MT-RJ connectors for multimode fiber optic cable connections.

3-8 Installation

Connecting to the Network

Each fiber optic link consists of two fiber optic strands within the cable: the transmit (TX) and the receive (RX). The transmit strand from a 2H258-17R port connects to the receive port of a fiber optic Fast Ethernet device at the other end of the segment. The receive strand of the applicable port on the 2H258-17R connects to the transmit port of the fiber optic Fast Ethernet device.

Enterasys Networks recommends labeling fiber optic cables to indicate receive and transmit ends. Many cables are prelabeled, providing matching labels or tapes at both ends of each strand of cable.

The following instructions detail the process used to connect a MT-RJ connector to a 2H258-17R port.

1. Remove the protective covers from the fiber optic ports on the applicable port on the device, and

from the connectors on each end of the cable.

NOTE: Leave the protective covers in place when the connectors are not in use to prevent contamination.

CAUTION: Do not touch the ends of the fiber optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants. Contamination of cable ends causes problems in data transmissions. If the ends of the fiber optic strands become contaminated, use a canned duster to blow the surfaces clean. A fiber port cleaning swab saturated with optical-grade isopropyl alcohol may also be used to clean the ends.

2. Insert the MT-RJ fiber optic cable connector on the cable into the MT-RJ connector on the

device until it clicks into place. See Figure 3-6.

CAUTION: To remove the cable connector, press on its release tab and then pull the connector out of the MT-RJ connector on the device.

3. Plug the other end of the cable into the appropriate port on the other device. Some cables may

be terminated at the other end with two separate connectors, one for each fiber optic strand. In this case, ensure that the transmit fiber optic strand is connected to the receive port and the receive fiber optic strand to the transmit port.

4. Verify that a link exists by checking that the port RX LED is on (flashing amber, blinking green, or solid green). If the RX LED is off, perform the following steps until it is on:

a. Verify that the device at the other end of the segment is ON and connected to the segment.

b. If there are separate fiber optic connections on the other device, check the crossover of the

cables. Swap the cable connections if necessary.

c. Check that the fiber optic connection meets the dB loss and cable specifications outlined in

Enterasys Networks Cabling Guide for multimode mode cabling.

If a link is not established, contact Enterasys Networks. Refer to Section 1.2 for details.

5. Repeat steps 1 through 3, above, until all connections have been made.

Removing the Chassis Cover

To remove the chassis cover, proceed as follows:

1. Disconnect the 2H258-17R from the network as follows:

a. Unplug both power cords from the rear of the chassis.

ELECTRICAL HAZARD: TURN OFF THE 2H258-17R BY UNPLUGGING THE POWER CORD FROM THE REAR OF THE CHASSIS.

AM HINTEN DES 2H258-17R STECHEI ABZIEHEN UM AUS ZU SCHALTEN. APAGUE EL 2H258-17R DESENCHUFE EL CABLE DE LA UNIDAD.

TIP: Before performing step b, mark the cables connected to the 2H258-17R according to their associated port numbers. This is recommended for ease of reinstallation.

b. Disconnect all network cables attached to the 2H258-17R.

2. If the 2H258-17R is rack mounted, remove it from the rack and remove the rackmount brackets

(refer to Chapter 3).

3. Use a Phillips screwdriver to remove the four screws attaching the cover to the chassis. (See

Figure B-1.)

4. Remove the cover by sliding it back until it clears the front of the chassis and then lifting it

straight up and off the chassis.

To reinstall the chassis cover, perform the removal procedures in reverse.

B.3 SETTING THE MODE SWITCHES

Figure B-2 shows the location of the mode switches and the switch settings for normal operation.

These switches are set at the factory and rarely need to be changed.

Switch definitions and positions are as follows:

• Switches 1 through 4 – For Enterasys Networks use only.

• Switch 5 – COM Port Autobaud. The default (OFF) position enables Autobaud sensing on the

COM port for Local Management sessions. Changing the switch to the ON position disables Autobaud sensing and sets the COM port to 9600 baud for Local Management sessions.

Setting the Mode Switches

• Switch 6 – Forced BootP.

NOTE: After changing the position of switch 6, DO NOT reapply power to the chassis until there is a station on the network acting as a BootP server, which contains the downloadable firmware image file.

DO NOT attempt a Forced BootP unless a BootP server has been configured for the 2H258-17R. The BootP server references the location of a station acting as a Trivial File Transfer Protocol (TFTP) server containing the 2H258-17R image file.

When the position of Switch 6 is changed and the power is cycled to the 2H258-17R, the device requests the image file location from the BootP server and uses TFTP to download the image from the TFTP server. If one of these requirements is not met, the 2H258-17R continues to request either the BootP server or the TFTP server until the RESET button on the 2H258-17R is pressed. Once the RESET button is pressed, the 2H258-17R resets after one minute and loads the image stored in FLASH memory.

• Switch 7 – Clear NVRAM. Changing the position of this switch resets NVRAM on the next

power-up of the device. All user-entered parameters, such as the IP address, device names, etc., are reset to the factory default settings. Once the 2H258-17R resets, you can either use the factory default settings or reenter your own parameters.

• Switch 8 – Reset Password/Community Names. Changing the position of this switch clears

user-entered passwords stored in NVRAM, and restores the factory default passwords on the next power-up of the device. Once the 2H258-17R resets, you can either use the factory default settings or reenter your own passwords.

NOTE: Do not change the position of switch 8 unless it is necessary to reset the module super-user configured passwords to their factory default settings.
