First, try using snmpV1 to model the switch. If it works and these symptoms are no longer present then getbulk should be disabled for Policy Manager use.
Snmp getbulk is used on both the client and server. The client uses getbulk when pulling information from ports such as displaying ports. The server will use getbulk for enforce and verify functions.This is how to disable it on the server (to affect Policy Manager enforce & verify):
This file NSJBoss.properties will need to be updated on the Netsight server system. The file is located as noted if NetSight was installed using the default directories.
- Windows: C:\Program Files\Extreme Networks\NetSight\appdata\
- Linux :/usr/local/Extreme_Networks/NetSight/appdata/
Add this line into the file. It may be placed anywhere. Note that XX is the IP address of the switch:
or, to disable it for all devices
Note: Default value is 5. The setting of -1 above disables getbulk entirely. For latency concerns, you can tune this to a lower value between 1 and 5 to see if that resolves the issue.
Once added, the Netsigth server service will needed to be restarted:
- Windows: right click on the NetSight services icon and select Restart Running Services
- Linux cli command: service nsserver restart
To disable snmp getbulk on the client (for port views):
The file app.properties will need to be edit (or created if it doesn't exist) on the client system. The file should be located on the client system under the users account:
- c:\Users\ < username > \AppData\Roaming\NetSight\app.properties
Add the lines:
Restart the Policy Manager Client
