Chapter8 Working with Linksets
Viewing Real-Time Data for a Linkset

Received Utilization
Chart
Displays the average Receive Utilization% for all links on the linkset as a
function of time, and optionally the Receive Utilization% for up to 16
individual links on the linkset.
To see the exact time and data coordinates for a data point, left-click the data
point. The coordinates are displayed in the format (hh:mm:ss, dd.dd), where:
•hh:mm:ss is the time for that data point in hours, minutes, and seconds.
•dd.dd is the receive utilization percentage for that data point.
Note For serial and HSL links on Cisco 7507 and 7513 series routers, the
displayed utilization data can vary by up to 5% from the actual
utilization—SGM might even display utilization data above 100%.
This variance results from the synchronization of Layer 2 counters
between the Versatile Interface Processor (VIP) CPU and the Route
Switch Processor (RSP) CPU on 7500 series routers. This variance
does not occur for links on Cisco 2600, 7200, or 7300 series routers.
To remove the data for a link or for the average from the chart, click the icon
in the SLC field. To return the data to the chart, click the icon again.
The total time displayed in the chart is specified in the Time Window (mins)
field.
New data points are added to the right side of the chart. When the chart
reaches the end of the time window (for example, after 5minutes, if the Time
Window (mins) field is set to 5), new data points continue to be added to the
right side of the chart, while old data points “drop off” the left side of the
chart.
If a poll is missed (for example, as a result of an SNMP timeout), SGM
ignores the missing data point, stops drawing the line, and waits for the next
valid data point to begin drawing the line again.
To scroll left, right, up, or down in the chart, drag the cursor while holding
down Ctrl and the left mouse button.
To zoom in on a section of the chart, drag the cursor while holding down Shift
and the left mouse button.
To reset the chart to the default view and scaling, click Reset.
