Introduction
Auto-Negotiation - Speed/Duplex Mode
The twisted pair ports on the front panel of the 9H532-17 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 module 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 9H532-17 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 9H532-17 cannot auto-negotiate, the 9H532-17 interface operates according to
the capability of the other device.
The 9H531-17 supports FDSE with 100 Mbps operation only. On the 9H532-17,
each switched Fast Ethernet port can be configured to operate in Full Duplex
Switched Ethernet (FDSE) mode, with 10 or 100 Mbps operation. FDSE allows
each port to provide up to 200 Mbps of bandwidth.
Runtime IP Address Discovery
This feature enables the modules to automatically accept an IP address from a
Boot Strap Protocol (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 IPaddress. If one has not yet
been assigned (module and SmartSwitch 9000 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 at an interval of one 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.

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 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 SmartTrunk links. The benefits of SmartTrunking
include the following:
• All purchased bandwidth is used.
• Distributed, resilient links increase reliability and performance.
• Multiple technologies are supported within a single trunk for maximum
flexibility.
Management
Management of the 9H531-17 and 9H532-17 modules and SmartSwitch chassis
and any optional equipment is accomplished using the Local Management
application or remote SNMP management stations. Local Management is
accessible through the RS232 COM port on the Environmental Module using a
local VT100 terminal, or a remote VT100 terminal via a modem connection, and
in-band via a Telnet connection. In-band remote management is possible through
WebView or any SNMP-compliant Network Management Software.
Local Management provides the ability to manage the 9H531-17 and 9H532-17.
Local Management information for non-Ethernet HSIMs or VHSIMs is included
in their respective user’s guide. For details on how to get manuals, refer to the
Related Manuals section in the Introduction.
WebView
The 9H531-17 and 9H532-17 modules can be managed by Cabletron WebView, a
browser-based utility. There is no software to install as this management
capability is built into each module.
Remote Monitoring (RMON)
The 9H531-17 and 9H532-17 support all nine Ethernet RMON groups. The
Statistics, Alarms, Events and History groups are enabled on all ports by default.
NOTE
For information on SmartTrunk configuration, refer to the
SmartTrunk User’s Guide.

Introduction
Cabletron Systems RMON Actions is a vendor-specific extension of RMON and
provides the ability to set an “Action” on any SNMPMIB variable. TheAction can
be triggered by setting an 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.
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 module up
to the set limit. 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.
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 to a destination
port within the chassis. This feature 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.
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 enables the receiving device to communicate with the transmitting
device, and to have it pause its transmission while the receiving device processes
the frames already received. Flow control can be enabled or disabled on a port-by-
port basis. Both devices must support the IEEE 802.3x standard for flow control to
work.
The 9H531-17 and 9H532-17 support 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.
Back pressure flow control is supported on all Ethernet ports operating in the
standard mode of operation.
802.1p Port Priority
The IEEE 802.1p standard is used to assign a default priority to the frames
received without priority information in their tag header, and to map prioritized
frames to the appropriate transmit queues.
The default priority-to-queue mappings are shown in Table 1-1. This
configuration can be changed by the administrator.

Introduction
1-6
Switching Options
The 9H531-17 and 9H532-17 provide IEEE Standard-based 802.1 switching or
SecureFast Switching Virtual Network Services. In the 802.1 mode (the default
mode of operation), the switch functions as an 802.1D switch. When until VLANs
are configured, it operates as an 802.1Q switch.
Standards Compatibility
The 9H531-17 and 9H532-17 are fully compliant with the IEEE 802.3, 802.3x,
802.3u, 802.1Q, and 802.1p standards. The 9H531-17 and 9H532-17 provide IEEE
802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability
of the network and protect against “loop” conditions. The 9H531-17 and 9H532-
17 support a wide variety of industry standard MIBs including RFC 1573 (MIB II),

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.
