We have been seeing a pronounced trend of customers making the transition to SNMP over the past year. Most of the feedback we get is that the transition was a lot easier that the customer had predicted. Consider the benefits SNMPv3 give you over SNMP v2c.

  • Encrypted Communications - no plain text community strings.
  • User Level Access Control - specific message types according to requesting device.
  • View Based Access Control - allow access to a part of a MIB rather than all or none.

 

Rolling out SNMP v3 should be accomplished is a two step plan:

  1. Place the new SNNP v3 configuration on one device ant test. This will typically be done in a lab environment.
  2. Roll-out the configuration to production devices using a configuration management tool.

 

Here are a couple of reference papers to get you started.
