Connectivity

1.1 CONNECTIVITY

The module connects t o Ethernet net works or w orkstatio ns through the fr ont panel conne ctors. The
ports support Unshielde d Twisted Pair (UTP) cables with an impedanc e betwee n 85 and 111 ohms
at lengths up to 100 meters. The ports are IEEE 802.3 10BASE-T and 100BASE-TX compliant.

1.2 HALF-DUPLEX/FULL-DUPLEX AUTO-NEGOTIATION

The fixed front panel ports on the module have the ability to auto-negotiate the ports’ mode of
operation (half-duplex or full-duplex) between two devices according to IEEE 802.3 standards.
During Auto-Negotiation, two devices automatically exchange information “telling” each other
their current operating mode. The Auto-Negotiation feature targets the maximum capability that
can be reached between the two devices. For example, the module can adjust to full-duplex
operation when the device on the other end of the connection can also adjust from half-duplex to
full-duplex. I f t he device on the other en d of th e connection can only operate in half-duplex mode,
then the module simply adjusts to operate in half-duplex mode.

1.3 PORT TRUNKING

Port Trunking is used for load balancing or load sharing. Port Trunking provides a mechanism to
group, or aggregate, multiple links of any technology together to scale the backbone bandwidth
beyond the limitations of a single link. All links are user-configurable so administrators can scale
the backbone bandwidth by adding Port Trunking. The benefits of Port Trunking include the
following:

• All purchased bandwidth is used.

• Distributed, resilient links increase relia bility and performance.

• Multiple technologies are supported within a single trunk for maximum flexibility.

1.4 REMOTE MONITORING (RMON)

The module supports the 1 , 2, 3, a nd 9 Ethernet RMON gro ups. The St atistic s, Alar ms, Ev e nts an d
History groups are enabled on all ports by default.

The 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

Port/VLAN Redirect Function

1.5 PORT/VLAN REDIRECT FUNCTION

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 module. This feature
allows frames, including those with errors, to be copied and sent to an analyzer or RMON probe.
The analyzer or RMON prob e will se e the data as if it were direct ly connec ted to the LAN se gment
of the source port.

The VLAN redirect func ti on is similar to the por t red ir ect function except tha t t he f rames r eceived
by the modul e are r edir ected t o a des ign ated d estin ation por t acco rding t o the VLAN cla ssification
of the frames received. Multiple VLANs can be directed to the same destination port. The VLAN
redirect function is only supported when the module is operating as an 802.1Q switch.

1.6 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 module supports frame-based 802.3x flow control. 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 not supported on ports operating in the half-duplex mode.

1.7 802.1 PORT PRIORITY

The 802.1 por t priority is us ed to assign a default priority to the frames received without prio rity
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.

1.8 MANAGEMENT

Management of the module can be either in-band or out-of-band. In-band remote management is
possible through any SNMP-compliant Network Management Software, such as Enterasys
Networks’ NetSigh t and Aprisma Manage ment T e chnology’s SPECTRUM for Open Systems suite
of management products. In-band management using Telnet and Enterasys Networks’ Webview is
also provided. Out-of-band Local Management is provided through the RJ45 COM port on the
front panel using a VT100 terminal or a VT100 terminal emulator.

Local Management provides the ability to manage the module. Refer to the MATRIX E5 Series

Modules Local Managemen t User’s Guide for more information.

1-4 Introduction

Switching Options

1.9 SWITCHING OPTIONS

The module provides 802.1Q switching between all of the front panel interfaces. In the 802.1Q
mode (the default mode of operation), the module functions as an 802.1D switch until you
configure VLANs. Up to 1024 VLANs can be configured.

IEEE 802.1Q switching allows migration to Virtual Network technologies without requiring the
replacement of existing equipment.

1.10 STANDARDS COMPATIBILITY

The 5H102-48 and 5H103-48 modules are fully compliant with the IEEE 802.3, 802.3u, 802.3x,

802.1D, and 802.1Q standards. The modules provide IEEE 802.1D Spanning Tree Algorithm

(STA) support to enhance the overall reliability of the network and protect against “loop”
conditions. The modules support a wide variety of industry standard MIBs including RFC 2737
(MIB I), RFC 1213 (MIB II), RFC 1757 (RMON), and RFC 1493 (Bridge MIB). A full suite of
Enterasys Networks Enterprise MIBs provide a wide array of statistical information to enhance
troubleshooting. For information on how to extract and compile individual MIBs, contact
Enterasys Networks.

1.11 LANVIEW DIAGNOSTIC LEDs

LANVIEW diagnostic LEDs serve as an important troubleshooting aid by providing an easy way
to observe the status of individual ports and overall network operations.
