Cacti Graphing problem

by David Farmer

Our graph on cacti I being cut off, see the following, we moved from a 30G lag to a 100G a few week ago and today are significantly exceeding 30G for the first time.

That would be great if a *new* router could be put in place. The old one wouldn't have to be turned down until the graphing stuff is all worked out with the new one.

Seems to me that putting a port on the LG server on the same network as the MICE web site wouldn’t be a bad plan if there’s appropriate physical proximity to make this easy.

Re: Looking glass

Yeah, that seems like a bad idea. Generally speaking, folks should never really be carrying the MICE /24 in their IGP’s anyway. It’s a bad idea, and can be harmful. Not carrying it (and using next-hop-self) protects both you and MICE. The IXP prefix shouldn’t, in theory, really be reachable from any device not directly connected in to that /24. Does MICE itself have general use transit available for website, OOB, graphing servers, etc, where this LG (or at least 1 leg of it) could live instead? -- Andrew Hoyos hoyosa(a)gmail.com > On Nov 3, 2017, at 10:30 AM, Steve Howard <showard(a)paulbunyan.net> wrote: > > Note that the IP address for the Looking Glass is within the MICE IP space and probably does not have connectivity to the global internet.
