Managing Ethernet MicroLAN Switches
Viewing the Statistics, Timer Statistics, and Performance Graph windows; using the repeater, board,
and port Alarm Limits windows; setting alarm limit s; link state traps, segmentation traps, and source
address traps
The Repeater menu lets you access windows to monitor and manage repeated
Ethernet networks supported by a SmartSwitch 2000 Ethernet MicroLAN Switch
(e.g., the 2E43-51 or 2E43-51R). Among these windows are repeater, board, and
port statistics windows (including Statistics, Timer Statistics, and Performance
Graph windows), repeater board, and port Alarm Limits windows, and repeater
board, and port Trap Selection windows.

Repeater Statistics

The statistical information collected and stored by your Ethernet MicroLAN
Switch provides you with detailed information about how much traffic your
network (or a segment thereof) is experiencing, including the sizes and types of
packets that make up that traffic, and how much of that traffic comprises packets
which have been badly formed or somehow mangled in transmission. These
statistics can give you a good overall sense of the usage your network, or network
segment, is experiencing.
To help you better understand and track the traffic your network is handling,
NetSight Element Manager provides you with a variety of statistical information
presented in three different formats: Statistics, Timer Statistics, and Performance
Graphs.
TIP
Although you can launch most statistics windows from both the Repeater and Module
menus, the information provided at both levels will be the same, since each “board” on the
Ethernet MicroLAN Switch is equivalent to a repeater channel.
