I have been running intermapper for years since 1.1b2, Intermaper has never lied to me, and has always shown me the truth when there is a problem. If the interface is showing discards, there is a reason. many times the switch reporting discards is not the switch with the problem, it is just reporting the issue on the line. The fact that it is discarding the packets shows that something is getting tossed in the bit bucket. Jumbo frames is one of my favorite discards. -j > > How do I explain to other support personnel just what it means when IM says > that but the actual hardware says something else? > Especially bosses - they want to see that IM is actually worth having but if > we can't trust what we see - then what? > > All opinions welcome. > > regards, > > Kevin > > ____________________________________________________________________ > List archives: > http://www.mail-archive.com/intermapper-talk%40list.dartware.com/ > To unsubscribe: send email to: [email protected] > > ____________________________________________________________________ List archives: http://www.mail-archive.com/intermapper-talk%40list.dartware.com/ To unsubscribe: send email to: [email protected]
