Overview

VNS3 supports a number of industry standard MIBs for use from a monitoring system doing SNMP polling.

Configuration

VNS3 SNMP support is enabled through the firewall. To enable access to the SNMP information add the following rule to your firewall using a source address from your network (either your public IP, or an internal IP available to the Controller via IPsec or Clientpack). There is no SNMP authentication in this beta. An example rule would be INPUT_CUST -p udp -s 69.69.70.70/32 --dport snmp -j ACCEPT (where 69.69.70.70 is your network’s public IP address).

VNS3 Admin SNMP FW rule Output

On your SNMP monitoring system:

  • Use SNMP v1c or v2
  • Community string of “vns3public”
  • The access to the SNMP information is “read only”

You should then be able to use a utility like “snmpwalk” to test: snmpwalk -v 1 -c vns3public -O e <vns3_manager_public_ip>

$ snmpwalk -v 1 -c vns3public -O e <vns3_manager_public_ip>
