Chapter 18. Using the Ethernet Network Interface
This chapter describes how to use the Ethernet interface. It includes “Displaying
Ethernet Statistics through the Interface Command”.

Displaying Ethernet Statistics through the Interface Command

Youcan also use the interface command from the GWCON environment to display
the following statistics.
+ interface 0 Self-Test Self-Test Maintenance
Nt Nt′Interface CSR Vec Passed Failed Failed
0 0 Eth/0 81600 5E 1 1 0
Ethernet/IEEE 802.3 MAC/data-link on SCC Ethernet interface
Physical address 000093808000
PROM address 000093808000
Input statistics:
failed, frame too long 0 failed, FCS error 0
failed, alignment error 0 failed, FIFO overrun 0
internal MAC rcv error 0 packets missed 0
Output statistics:
deferred transmission 6 single collision 2
multiple collisions 0 total collisions 2
failed, excess collisions 0 failed, FIFO underrun 0
failed, carrier sense err 0 SQE test error 0
late collision 0 internal MAC trans errors 0
RISC Microcode Revision: 1
These statistics have the following meaning:
Nt Global network number.
Nt′This field 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
