How to properly rediscover a node (SNMP update)

I've got a bunch of devices that have not had their SNMP name, location, or contact changed from device default. I've got a summer coop going into devices to update these. The coop is also changing the community.

What is the proper procedure to get the node to reflect the new properties. If I press the "Rediscover" button it DOES NOT COMPLAIN that its using the wrong community. It says "Discovery successfuly completed" in green. If I press "poll now", it says is successfuly completed, yet its using the wrong community. When I press "List Resources", it finally tells me I have an SNMP problem.

Surely that's not as intended?

If I DID NOT change community, would the rediscover update the name, location, and contact info automatically?

Is there a procedure to get the node name to match the new SNMP device name? After fixing everything else, the node name is still "Unknown"

You have a tool for updating these parameters from a GUI. You should make that tool free or include it with your Orion products. It should be alot easier to fix SNMP device information for screwed up nodes.

Just re-add the node, use the same IP, but new SNMP community name. It will add the node in place of the current one.

Right,

That's what I did pre 10, but they have this rediscover button.. What is it supposed to do?

Can someone tell me what the rediscover button is supposed to do.

Just yesterday I did a network upgrade at a site, replacing the Nortel gear with Juniper switches. I went to the old nortel node and did a rediscover and poll, but nothing changed. I finally had to delete this device in Manage Nodes then rediscover to get it to reflect the new device.

Is that the correct procedure for learning a new device. If so, I not crazy about it.

OK, I'm working with an upgraded box. Automatic rediscovery seems to have found the new system name and description. The stuff in the details box looks good. But the interfaces are all screwed up. Example follows.

Also I get interface disappeared errors for these. Going into "List Resources" does not clear this list. The only way I found to fix it is to delete the interfaces in Manage Nodes.
