Introduction
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.

Full Duplex Switched Ethernet
Each switched Fast Ethernet port on the SmartSwitches supports 10/100 Mbps operation and can
be configured to operate in Full Duplex Switched Ethernet (FDSE) mode. FDSE allows each port
to provide up to 200 Mbps of bandwidth.

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.
For more information on SmartTrunk configuration, refer to the Cabletron Systems SmartTrunk
User’s Guide.
1.1.6
Remote Monitoring (RMON)
The SmartSwitches support all nine Ethernet RMON groups. The Statistics, Alarms, Events and
History 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 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.
NOTE
The module will reboot after RAD is successful.
