Taking a Snapshot of Your Network

Nortel Networks recommends that you periodically gather and save the

forwarding and routing tables maintained by the protocols running on each router.

You can use the Technician Interface or the Statistics Manager to do this.

Access to this information will be helpful when you are troubleshooting problems

in the future. For example, when troubleshooting a problem, you may find the

next-hop address to a given destination does not match that in a table you saved

previously. This would help you to conclude that there may be a problem with the

connection to the node that should be the next-hop address.

You can use the Technician Interface to save tables (or any other Technician

Interface displays) to a single file as follows:

Enter the following command:

record open

is the number or letter of the router’s file-storage medium.

is the name of the file you are creating to store the display text.

Display the routing tables.

Enter the following command to copy the file from memory to the

router’s file-storage medium and terminate the recording:

record close

To learn more about the Technician Interface recording feature, enter this

command:

help record

You can use the Statistics Manager to save tables to files as follows:

Use the Statistics Manager Screen Manager tool to add the routing tables

in the Default Screens window to the Current Screens List window.

For each routing table:

Use the Launch Facility tool to display the table.

Use the File

Save option to save the contents of the table to a

formatted ASCII file.
