Accessing the Ethernet Interface Operating Process
Tomonitor information related to the Ethernet Network Interface, access the
interface monitoring process by doing the following:
1. At the OPCON prompt, enter talk 5. For example:
*talk 5
The GWCON prompt (+) is displayed on the console. If the prompt does not
appear when you first enter GWCON, press Return again.
2. At the GWCON prompt, enter the configuration command to see the protocols
and networks for which the router is configured. For example:
+configuration
See page “Configuration” on page130 for sample output of the configuration
command.
3. Enter the network command and the number of the Ethernet interface. In this
example:
+network 0
ETH>
The Ethernet monitoring prompt is displayed. Youcan now view information
about the Ethernet interface by entering monitoring commands.
Ethernet Interface Monitoring Commands
This section summarizes and explains the Ethernet monitoring commands. Enter
commands at the ETH> prompt. Table34 lists the monitoring commands.
Table34. Ethernet monitoring command Summary
Command Function
? (Help) Displays all the commands available for this command level or lists
the options for specific commands (if available). See “Getting Help”
on page 10.
Collisions Displays collision statistics for the specified Ethernet interface.
Exit Returns you to the previous command level. See “Exiting a Lower
Level Environment” on page 11.
Collisions
This command shows the counts of transmissions for packets that incurred
collisions before successful transmission. Counters are given for packets sent after
the collision XXXXx packets sent after 15 collisions. Increasing numbers of packets
transmitting with collisions and higher numbers of collision per packet are signs of
transmitting onto a busy Ethernet.
These counters are cleared by the OPCON clear command. This data is exported
via SNMP as the dot3CollTablecounter.
