Setting Router Parameters
The first indication of potential troubles in a network are often detected by change in the utilization of an
interface. Dean, therefore, wants to configure the NM-NAM to retrieve interface statistics from the host router
via SNMP. To configure the NM-NAM with the router’s SNMP community strings, Dean performs the
following steps:
Step 1. Click Setup > Router Parameters > Router Information. The Router System Information
dialog box is displayed.
Step 2. Enter the IP Address of the Router configured during NAM installation and the correct read-
write community strings as configured on the host router and click Apply to store in the NAM
memory.
Step 3. Click the Test button to verify that the strings were entered correctly. Click OK to close the
verify window.
Step 4. Dean also checks to see that NBAR is enabled on the Router so he can retrieve the
applications discovered on each interface. Click Setup > Router Parameters > NBAR
Protocol Discovery. The NBAR Status dialog is displayed. Verify that NBAR is enabled. If not,
select enable. (If using IOS then click Save for the changes to be written to the start-up config).
Step 5. To see details of which interfaces are enabled for NBAR, click Details.
