Troubleshooting Routers

1-20

If you click an attribute and click Retrieve, the Site Manager retrieves and

displays all of the values of that attribute. You can retrieve more than one

attribute at a time.

• The Screen Manager tool allows you to select windows of statistics from the

Default Screens window, which contains a list of statistics windows provided

with Site Manager, and

— Add them to the Current Screens List window so that you can launch

these windows.

— Copy them to the User Screens window so that you can customize these

windows.

• The Launch Facility tool allows you to select from a list of the statistics

windows you added to the Current Screens List window to display one.

When you launch a statistics window, the Statistics Manager queries the

router for the values and displays the values.

• The Screen Builder allows you to

— Build windows of statistics from scratch

— Customize statistics windows you copied to the User Screens window.

Refer to Managing Routers and BNX Platforms for detailed instructions on using

the Statistics Manager.

Using Ping

The ping command is available both from the Site Manager Administration menu

and the Technician Interface. When you enter the ping command, the router, not

the Site Manager, issues an ICMP echo request. Options include packet size,

number of repetitions, and the capability to trace the path of the ICMP (Internet

Control Message Protocol) echo request.

When you lose AppleTalk, APPN, IP, IPX, OSI, or VINES connectivity, use the

ping command to isolate the problem interface. Try pinging the end node that has

connectivity problems. If you fail to get a response, ping the local router interface,

and then ping each router interface along the way to the problem node.

If after attempting to ping a device, the response is “Unknown Network” or

“Network Unreachable,” check the local node's routing table and its default

gateway deﬁnition.
