All of the Omega graph displays are automatically updated every few
seconds when Omega is configured for a terminal with cursor control
capabilities (such as ANSI). When using the terminal without cursor
control, you can manually update the screen by pressing the spacebar.
Hub Overview
This option displays a summary of Ethernet frames the hub has processed
since the last reset.
To view hub-wide statistics:
1.
Select
Hub overview
from the
Hub Statistics
menu to display a
similar graph that combines statistical data from all modules:
Transmit Collisions
Frames with a collision occurring internal to the hub module; i.e.,
two or more ports attempted to transmit at the same time (avail-
able at the hub level only).
Jabber Lockups
Transmissions of excessive length that caused the hub module to
enter Jabber Lockup mode (available at the hub level only).
Port Collisions
Frames with a collision occurring external to the hub module (an
Ethernet collision signal detected); i.e., a port attempted to trans-
mit at the same time as some other device external to the hub
Late Collisions
Port collisions that occurred after 64 byte-times of the frame had
elapsed.
Port Partitions
The number of times the port was automatically partitioned Off
Line.
Data Rate
Mismatches
Frames transmitted at a data rate outside of Ethernet/IEEE 802.3
specifications.
Source Address
Changes
The number of times a port or module detects a different incom-
ing MAC address, even if the port or module has previously
detected that address.
