RE: [NV-L] SNMP polling config file(s)

["Sperry, Kevin" <Kevin.Sperry@us.ngrid.com>]

OK,

 

thanks for the very good answer. I tried the help button in the SNMP configuration dialog box but I receive an error regarding a path.  I also check the manuals on line and which are the same as I have in paper form and no mention of what all the fields do.  So I am guessing and don't want to guess.

 

Perhaps you can help me get help working or help me understand a few fields.

 

1. If I deselect/uncheck the Discovery Poll for a specific node or Smartset, netmon will not use this device (or in the case of a Smartnet) or devices to discover new nodes.  Will NetView still discover new interfaces on an existing device if Discovery Poll is unchecked?

 

2. What does Configuration Polling Interval do?  Polling the configuration of a device for what?  Is this discovery Polling? Are Discovery polling and Configuration polling the same thing?

 

Thank you for your valued help,

"Discovery Poll" is something netmon does to try to discover new devices. It pulls the ARP cache (using SNMP) of the devices it already knows about and sees whether there are any addresses there which it has not already discovered and then it tries to discover them. This is set by default. If you uncheck the box, netmon will not find anything that it has not already found.

"Discover Node(s) Managed" is the way netmon usually discovers new nodes. This too is set by default. If you uncheck it, new devices are put on the map as unmanaged and you would have to select them or use nvmapuitl.sh to explicitly manage them before netmon would start to poll them.

New routers and networks on the other hand are usually discovered as unmanaged. To go to the next hop you have to manage them.

You should be able to find out for yourself what all the buttons and fields mean by clicking the Help button on the SNMP Configuration GUI. It's context-dependent. Alternatively, there is a lot of information in the NetView Administrator's Guide. You can view or download all the current NetView documentation here:
