Deleting NAM Community Strings
To delete the NAM community strings:
Step 1 Choose Administration > System > SNMP Agent.
At the bottom of the window, the NAM Community Strings Dialog Box displays.
Step 2 Select an entry, then click Delete.
Caution Deleting the NAM community strings blocks SNMP requests to the NAM from outside SNMP agents.
The community string is deleted.
Testing the Router Community Strings
Before the router can send information to the NAM using SNMP, the router community strings set in the
NAM Traffic Analyzer must match the community strings set on the actual router. The Router
Parameters dialog box displays the router name, hardware, Supervisor engine software version, system
uptime, location, and contact information.
The local router IP address and the SNMP community string must be configured so that the NAM can
communicate with the local router.
To set the community strings on the router, use the router CLI. For information on using the CLI, see the
documentation that accompanied your device.
Caution The router community string you enter must match the read-write community strings on the router.
Otherwise you cannot communicate with the router.
To test router community strings:
Step 1 Choose Setup > Managed Device > Device Information.
The Device Information dialog box displays.
Step 2 Enter the Device's Community String.
Step 3 Click Test Connectivity.
Step 4 Wait for a while for NAM to communicate with the Device. If it comes back OK, then click on Submit.
System Time
The NAM Traffic Analyzer gets the UTC (GMT) time from one of two sources, depending on its the
NAM type. All NAMs can be set up to get their time from an external NTP server. Following is the
second option per NAM type:
• WS-SVC-NAM-1 and WS-SVC-NAM-2 can get their time from the switch.
• NME-NAMs can get their time from the router.
