1. Pending Device Discovery (Les Begnaud)
--- Begin Message ---
We have a process in which we stage devices at our office before sending out
into the field. There are currently two situations where we can get into a
state that leaves a device not added to netdisco:
* Replacing a failed device
o The mgmt. IP of the device is not routable, as the IP is being routed to
the site, not to our office staging area
* Creating a brand new site
o If a user forgets to do the discovery, we have to wait until the device is
on site and online before running a discover
o This is prone to being forgotten and then we are left with the device not
being discovered until it is "found" later
I think a clean solution to both problems would be a way to stage a device to
discover. A simple solution would be to manually add it to the devices table in
the DB with some flag that says it's undiscovered, a better solution might be
to update the schema to include a pending devices table that gets discovered on
a different interval than the regular devices.
It's also possible that this functionality already exists, and I just am not
looking in the right place.
As a side note, neighbor discovery helps us out often here, but the router
product that we use doesn't support LLDP MIBS... so there's a big break in the
dynamic discovery that can happen. The router can be discovered via OSPF, but
the switches behind it won't be discovered (though a replaced device with a new
IP can be)
