When is it necessary to use this(DHCP Snooping Database Agent)? We are looking at enabling DHCP snooping. We have WIN2k3 DHCP servers. I dont believe we need too.
I am following this document, thanks.
My original response is still applicable as it is part of the minimal configuration for DHCP snooping. The database agent ensures that database entries are restored after a restart or switchover you have to specify a place to store the binding database via the agent.
Now whether or not you can get away without using the command I'm not sure. I believe it's there for reason stated earlier ie restart/switchover. If it automatically stores the database in RAM, which I'm leaning towards since if a reboot occurs you would loose all of your bindings. Something to lab and test, but I would recommend using the minimal configuration and specifying a place to store the binding database in the event of a reload you don't loose your dhcp bindings.
Under your link or the link I'm posting there's a section that says "Minimum DHCP Snooping Configuration" you must do these steps at a minimum. There is also a few examples of where or how to use the agent to store the binding database.
