The 9E312/9E423 Module View

The number of packets currently queued by the device for transmission. The amount of device memory devoted to buffer space, and the trafﬁc level on the target network determine how large the output packet queue can grow before the device begins to discard packets. This statistic applies only to the Output Table.

Packets Received

Displays the total number of inbound packets.

Packets Transmitted

Displays the total number of packets transmitted onto the network.

Making Sense of Interface Statistics

The statistics available in this window can give you an idea of how an interface is performing. By using the statistics in a few simple calculations, it’s possible to get a sense of an interface’s activity level.

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 packets discarded inbound

•Received Discards /Packets Received

To calculate the percentage of packets discarded outbound

•Transmit Discards /Packets Transmitted

Testing and Disabling the Current Interface

With the Test button you can test the current interface (e.g., by performing a loopback or some other transmission test).

With the Test and Disable buttons, you can test or disable the current interface. The operational states of these two options are:

Test	The interface will be in some test mode and no operational
	packets can be passed.
Disable	The interface will be in a closed state.
