2-18 I/F Summary Information

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.
