Using the SEHI100TX Hub View

Port display form options are:

Load

Shows a percentage for each active port that represents that portÕs portion of the theoretical maximum trafÞc level Ñ for Ethernet interfaces, 10 megabits per second; for Fast Ethernet interfaces, 100 megabits per second.

Traffic

Displays port trafÞc data in a packets/second format.

Collisions

Displays port trafÞc data in a collisions/second format. The SEHI100TX counts both receive collisions Ñ those collisions it detects while receiving a transmission

Ñand transmit collisions Ñ those it detects while transmitting (i.e., a port in the SEHI100TX-managed stack transmitted one of the colliding packets); however, those counts are combined and a single total value is displayed.

Errors

Shows port trafÞc 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

For error type descriptions, see Checking Statistics, page 2-16.

Frame Sizes

Displays a percentage for each active port that represents what portion of that portÕs trafÞc is of a speciÞc size, measured in bytes. You can display any one of the following frame sizes:

¥Runts (packets with fewer than 64 bytes)

¥64-127

¥128-255

¥256-511

¥512-1023

¥1024-1518

¥Giants (packets with more than 1518 bytes)

NOTE

For the statistical port display form options listed above, three dashes (- - -) will display for all inactive ports; any active (green) port will display a numeric value, even if itÕs 0.0000.
