]
Select number of times the Switch will be polled between
20
and
200
. The
default value is
20.
ExDefer
Counts the number of frames for which the first transmission attempt on a
particular interface was delayed because the medium was busy.
LateColl
Counts the number of times that a collision is detected later than 512 bit-
times into the transmission of a packet.
Show/Hide
Check whether or not to display ExDefer, LateColl, ExColl, SingColl, and
Coll errors.

Size
The Web Manager allows packets received by the Switch, arranged in six groups and classed
by size, to be viewed as either a line graph or a table. Two windows are offered.

Stacking Information
To change a switch’s default stacking configuration (for example, the order in the stack), see
Box Information
in the
Configuration
folder.
The number of switches in the switch stack (up to 12
total) are displayed in the upper right-
hand corner of your web-browser.
The icons are in the same order as their respective Unit
numbers, with the Unit 1 switch corresponding to the icon in the upper left-most corner of the
icon group.
When the switches are properly interconnected through their optional Stacking Modules,
information about the resulting switch stack is displayed under the
Stack Information
link.
To view the stacking information, click on the
Stacking Information
link from the
Monitoring
folder:

The following parameters are displayed:
Parameters
Description
Box ID
Displays the switch’s order in the stack.
User Set
Box ID can be assigned automatically (Auto), or can be assigned statically.
Default is Auto.
Type
Displays the model name of the corresponding switch in a stack.
Exist
Denotes whether a switch does or does not exist in a stack.
Start Port
The Start Port refers to the first port of a switch within a switch stack and
denotes the consecutive port count of the switch stack.
Priority
Displays the priority ID of the Switch. The lower the number, the higher the
priority. The box (switch) with the lowest priority number in the stack is the
Master switch.
Prom Version
Shows the PROM in use for the Switch. This may be different from the
values shown in the illustration.
Runtime Version
Shows the firmware version in use for the Switch. This may be different from
the values shown in the illustrations.
H/W Version
Shows the hardware version in use for the Switch. This may be different
from the values shown in the illustration.
Device Status
The
Device Status
window can be found in the
Monitoring
menu by clicking the
Device
Status
link. This window shows the status of the physical attributes of the switch, including
power sources and fans.
