The IRM2 Chassis View
The I/F Summary window provides a variety of descriptive information about
each interface on your device, as well as statistics which display each interface’s
performance.
The following descriptive information is provided for each interface:
UpTime
The UpTime field lists the amount of time, in a days, hh:mm:ss format, that the
device has been running since the last start-up.
Index
The index value assigned to each interface on the device.
Type
The type of the interface, distinguished by the physical/link protocol(s) running
immediately below the network layer.

A text description of the interface
Physical Status
Displays the current physical status — or operational state — of the interface:
Online
or Offline.
Logical Status
Displays the current logical status — or administrative state — of the interface:
Up
or Down.
Interface Performance Statistics/Bar Graphs
The statistical values (and, where available, the accompanying bar graphs) to the
right of the interface description fields provide a quick summary of interface
performance. You can select the statistical value you want to display and the units
in which you want those values displayed by using the two menu fields directly
above the interface display area, as follows:
1. In the right-most menu field, click on the down arrow and select the unit in
which you wish to display the selected statistic: Load, Raw Counts, or Rate.
2. Once you have selected the base unit, click on the down arrow in the left-most
field to specify the statistic you’d like to display. Note that the options available
from this menu will vary depending on the base unit you have selected.
NOTE
Bar graphs are only available when Load is the selected base unit; if you select Raw
Counts
or Rate, the Bar Graph column will be removed from the interface display.
