1.3
OVERVIEW
The 6H122-16 (Figure 1-1) is a Fast Ethernet interface module for the
Cabletron Systems 6C105 chassis. The module provides sixteen RJ45
switched ports for unshielded twisted pair (UTP) cabling connectivity.
The 6H122-16 is used to connect individual high-bandwidth user devices,
such as workstations, and provide a central switching point for multiple
10/100 Mbps Fast Ethernet segments.
1.3.1
Connectivity
The 6H122-16 connects to Ethernet/Fast Ethernet networks or
workstations through sixteen RJ45 ports on the front panel. These ports
are IEEE 802.3u 100BASE-TX compliant, and use Category 5 unshielded
twisted pair cables of lengths up to 100 meters with impedances between
85 and 111 ohms.
1.3.2
Management
Management of the 6H122-16 module and 6C105 chassis and any
optional equipment is accomplished using Local Management tools or
remote SNMP management stations. Local Management is accessible
through the front panel RS232 COM port using a local VT100 terminal,
or a remote VT100 terminal via a modem connection. Local Management
is also accessible in-band via a Telnet connection. In-band remote
management is possible through any SNMP compliant Network
Management Software.

6H122-16 User’s Guide
Chapter 1: Introduction
1.3.3
Distributed Chassis Management
From a management perspective, the 6C105 SmartSwitch 6000 chassis
can be viewed as a single entity with a single IP address. Its management
functions are distributed to all modules. This means a single module in
the chassis, such as the 6H122-16, can be used to manage the entire
chassis, and any other attached module through Local Management,
SNMP, or Telnet applications.
1.3.4
Switching Options
The 6H122-16 provides 802.1D switching, 802.1Q switching, or
SecureFast Switching Virtual Network Services between all of the front
panel interfaces.
SecureFast switching and 802.1Q switching allow for future migration to
Virtual Network technologies without requiring the replacement of
existing equipment.
1.3.5
Full Duplex Switched Ethernet
Ports 1 through 14 support Full Duplex Switched Ethernet (FDSE)
operation if the port is operating in Standard Ethernet mode (10 Mbps).
This provides up to 20 Mbps of bandwidth. Ports 15 and 16 also support
Full Duplex operation in Fast Ethernet mode (100 Mbps). This provides
up to 200 Mbps of bandwidth.
1.3.6
Remote Monitoring
The 6H122-16 supports all Ethernet Remote Monitoring (RMON)
groups, which include Statistics, Alarms, Events and History. These four
groups are enabled on all ports by default.
Cabletron Systems 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.

Overview
1.3.7
SmartTrunk
SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’
terminology for load balancing or load sharing. SmartTrunk technology
provides an easy-to-implement mechanism to group, or aggregate,
multiple physical links 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 SmartTrunk
links. The SmartTrunk benefits are as follows:
•
•
•
All purchased bandwidth is used.
Distributed, resilient links increase reliability and performance.
Multiple technologies are supported within a single trunk for
maximum flexibility.
For more information about SmartTrunk, refer to the Cabletron Systems
SmartTrunk User’s Guide.
1.3.8
Runtime IP Address Discovery
This feature enables the modules to automatically accept an IP address
from a BootP server on the network into NVRAM without requiring a
user to enter an IP address through Local Management.
When the modules are connected to the network and powered up,
Runtime IP Address Discovery (RAD) checks the modules for an IP
address. If one has not yet been assigned (module and 6C105 chassis IP
address set to 0.0.0.0), RAD checks to see if any of the module interfaces
have a link. If so, RAD sends out Reverse Address Resolution Protocol
(RARP) and BootP requests to obtain an IP address from a RARP or
BootP server on the network.
The RAD requests start out at an interval of one 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.
6H122-16 User’s Guide

Chapter 1: Introduction
1.3.9
Port 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 or
multiple source ports to a destination port(s) within the chassis. This
feature functions at the bit level, which allows all packets, 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 is directly connected to
the LAN segment of the source port(s).
1.3.10 Auto-Negotiation
Twisted pair ports on the 6H122-16 module have the ability to
auto-negotiate the type of connection required to provide a link to another
device. During Auto-Negotiation, two devices automatically exchange
information “telling” each other what their operating capabilities are. The
Auto-Negotiation feature targets the maximum capabilities that can be
reached between the two devices. For example, the 6H122-16 adjusts to
100 Mbps when the device on the other end of the connection can also
adjust between 10 Mbps or 100 Mbps. If the device on the other end of
the connection can only operate at 10 Mbps, then the 6H122-16 adjusts to
10 Mbps operation.
When Auto-Negotiation is supported at both ends of a link, the two
devices dynamically adjust to full or half duplex operation based on the
maximum capability that can be reached between the two devices. If the
device connected to the 6H122-16 cannot auto-negotiate, the 6H122-16
interface operates according to the capabilities of the other device.
All ports support standard Ethernet, standard full duplex
operation, and Fast Ethernet. Ports 1 through 14 do not
NOTE
support Fast Ethernet in full duplex operation. However, ports
15 and 16 do support full duplex Fast Ethernet.
1.3.11 Broadcast Suppression
Broadcast Suppression allows a limit to be set on the number of receive
broadcast frames per port/per second to be forwarded out the other ports
on the module. Any broadcast frames above the specified limit are
dropped. In the event that broadcast frames are being suppressed,
multicast and unicast frames continue to be switched.

Overview
1.3.12 Standards Compatibility
The 6H122-16 is fully compliant with the IEEE 802.3u standard. The
6H122-16 provides IEEE 802.1D Spanning Tree Algorithm (STA)
support to enhance the overall reliability of the network and protect
against “loop” conditions. The 6H122-16 supports a wide variety of
industry standard MIBs including RFC 1213 (MIB II), RFC 1757
(RMON), RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB). A full suite
of Cabletron Systems Enterprise MIBs provide a wide array of statistical
information to enhance troubleshooting.
1.3.13 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. Chapter 4 provides details about the 6H122-16
LANVIEW LEDs.
1.3.14 Year 2000 Compliant
The 6H122-16 module and 6C105 chassis have an internal clock that can
maintain the time and date beyond the year 1999.
