Has anyone had experience with lots of le0: Received packet with ENP bit in rmd cleared le0: Received packet with STP bit in rmd cleared messages? If you know of a particular manufacturer's machine that generates them, great. If it's symptomatic of some particular con- nector or some such dying, that'd help too. Some background: Our network is partitioned into four parts (at least, as is relevant to the current problem). The parts consist of the loop with a bunch of 3/50s in it, two lengths connected by fiber optic cable, and everything in the middle. The bogon packets are only seen by machines connected to the lower fiber optic section in the map below. They were also being seen by the 3/50 on the other fiber section, but swapping our Delni and our TCL stopped that. Only the Suns w/ Lance ethernet chips and the cisco boxes have noticed the packets. fiber optic 3/280 | \ V 3/50 +----------O-+--@---@---^---< cisco terminal server | bunch | | of | 3/50 3/260 HP9000 cisco | 3/50s +--^---V----^---V---^---V--^----V---< cisco +----------O-+ 3/260 HP9000 IBM PC cisco | / \ IBM 3/280 \ PC gateway \ 3/50 3/60 @---@----V--------V---^--V--^---< cisco terminal server ^ uVax II Ridge 3/50 | fiber optic Ideas? Thanks. [[ These messages were mentioned and discussed in v6n28, v6n40, and v6n50, but I don't think anyone came up with a good solution to the problem (an explanation was given in v6n40). If anyone has any new ideas on this, please send them in. --wnl ]] Dieter Muller dieter%nmt@relay.cs.net dieter@jupiter.nmt.edu

You probably have a bad transceiver on the network that the Sun 3/50's are on. We ran into the same problem. The only reason that we managed to find the problem was that the bad transceiver was the transceiver that a fiber repeater was plugged into. The bad packets were showing up on both sides of the network. The best way to track this this down is to swap out transceivers, one by one. It's not much fun, but it works.
