Using the STS16-20 Chassis View

Transmit Queue Size (Transmit Packets only)

The number of packets currently queued for transmission from this interface. The amount of device memory devoted to buffer space and the trafÞc level on the target network determines how large the output packet queue can expand before the module will begin to discard packets.

Packets Transmitted (Transmit Packets only)

The number of packets transmitted by this interface.

Making Sense of Detail Statistics

By using a few simple calculations, the I/F Statistics window can give you a good sense of the activity level and performance of the selected interface:

To calculate the percentage of input errors:

Received Errors /Packets Received

To calculate the percentage of output errors:

Transmitted Errors /Packets Transmitted

To calculate the total number of inbound and outbound discards:

Received Discards + Transmitted Discards

To calculate the percentage of inbound packets that were discarded:

Received Discards /Packets Received

To calculate the percentage of outbound packets that were discarded:

Transmit Discards /Packets Transmitted

NOTE

Unlike the Interface Detail window, which this window replaces, the Interface Statistics window does not offer Disable or Test options. These options are available in the Interface Group window, accessed via the System Group window (DeviceÑ>System Group). Refer to your Generic SNMP UserÕs Guide for more information on the System Group and Interface Group windows.
