•
Device, Module, and Port status descriptions.
•
Device, Module, and Port statistics, which provide a complete breakdown of
packet activity.
•
Device, Module, and Port-level pie charts, graphs and meters, for a graphic
representation of the types and levels of traffic passing through the device.
(For more information about pie charts, graphs and meters, see the Charts,
Graphs and Meters
chapter in the SPMA Tools Guide.).
Port Display Form
You can change the type of information displayed for each port in the device by
using the Port Display Form option on the Device and Module menus. Changing
the port display form via the Device menu will affect all ports in the SEHI-
controlled stack; changing the display form via the Module menu will affect only
those ports on the selected device.
To change the port display form:
1.
Click on the Device button to display the Device menu, or on the Module
Index box to display the Module menu.
2.
Drag down to Port Display Form, then right as necessary to select one of the
port display options. The current selection will be displayed in the Port Display
Form field on the port display.
Port display form options are:
Load
Shows a percentage for each active port that represents that port’s portion of the
theoretical maximum traffic level — for Ethernet networks, 10 megabits per
second.
Collisions
Displays port traffic data in a collisions/second format. The SEHI counts both
receive
collisions — those collisions it detects while receiving a transmission —
and transmit collisions — those it detects while transmitting (i.e., a port in the
SEHI-managed stack transmitted one of the colliding packets); however, those
counts are combined and a single total value is displayed.
Errors
Shows port traffic errors in an errors/second format. You can display any one of
the following types of errors:
•
Total errors
•
Alignment errors
•
CRC (Cyclic Redundancy Check) errors
•
Runts
•
Giants
•
OOW (Out-of-Window) Collisions
