We are experiencing network problems on our ethernet lan. Large quantities of CRC errors are occurring. Our focus is on the Dec DEMPR units. Has anyone experienced difficulties with these units. Any replies appreciated.

Has anyone > experienced difficulties with these units. I don't know of any specific ill repute associated with DEMPR's. Our last major net disease was one bad thin wire ethernet card that was slobbering over everybody else's messages, and *not* being isolated by our thin-wire device (cabletron DEMPR equivalent). Check that your ethernet follows the conservative side of all the ethernet configuration rules, then start unplugging things till you isolate the bad branch/unit... If this isn't a breakdown, but an on-going problem you've just recognized, check the cabling and little things like heart-beat presence corresponding to type of device. pithy quote of the day: "...the worst problem with thin-wire is the existance of arcnet cables"... -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)
