That’s what a higher level management user interface is for. I’d be happy to finally see someone do this in an abstracted way so it could be a cli, a Web interface, or some xml-rpc thingy or whatever is the standard of the day. > ifconfig is not the place, especially since it would have to query a daemon running somewhere else anyway. Otherwise we’ll end up with ndp, ospf, isis, bgp, ipsec, and the apache, varnish, and squid status there as well. > I'm not sure how this could be done efficiently, without any ill effects, but yes, it's likely that doing it in userspace is a safer way. With CDP you have to capture just one packet, parse it and update the values, with some of the examples, this is not the case. :) But I got the point.
