Chapter 18. Using the Ethernet Network Interface

This chapter describes how to use the Ethernet interface. It includes ªDisplaying Ethernet Statistics through the Interface Commandº.

Displaying Ethernet Statistics through the Interface Command

You can also use the interface command from the GWCON environment to display the following statistics.

These statistics have the following meaning:

Nt Global network number.

Nt¢ This ®eld is for the serial interface card. Disregard the output.

Interface

Interface name and its instance number.

CSR Command and status register address.

Vec Interrupt vector

Self-Test: Passed

Number of self-tests that succeeded.

Self-Test: Failed

Number of self-tests that failed.

Maintenance: Failed

Number of maintenance failures.

Physical address

The Ethernet address of the device currently in use. This may be the

PROM address or an address overwritten by some other protocol.

PROM address

The permanent unique Ethernet address in the PROM for this Ethernet interface.

Interface restarts

The number of times the Ethernet chip timed out, or the Ethernet driver
