Introduction

This chapter introduces the 2H252-25R SmartSwitch 2200 device and provides information about how to obtain additional support from Enterasys Networks.

Important Notice

Depending on the firmware version used in the 2H252-25R, some features described in this document may not be supported. Refer to the Release Notes shipped with the 2H258-17R to determine which features are supported.

1.1 OVERVIEW

The 2H252-25R (Figure 1-1) is a high-performance Fast Ethernet switch that provides 24 auto-negotiating 10/100 BASE-TX ports via RJ45 Interfaces and one optional High Speed Interface Module (HSIM) or Very High Speed Interface Module (VHSIM).

Introduction 1-1

Overview

The 2H252-25R 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 2H252-25R ports can be configured to control frame traffic in several ways, including prioritizing traffic flow according to protocol type. The 2H252-25R 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 2H252-25R may be used as a tabletop unit or can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2H252-25R 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 2H252-25R connects to Ethernet networks or workstations through the auto-negotiating 10/100 BASE-FX ports on the front panel. 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 2H252-25R 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 2H252-25R will reboot after RAD is successful.

1.1.3 Full Duplex Switched Ethernet

Each switched Fast Ethernet port on the 2H252-25R 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.

Introduction 1-3

Overview

1.1.5 Remote Monitoring (RMON)

The 2H252-25R 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.

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 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.
