I wouldn't be comfortable with any more than a few each year from any one device. At most. Soft errors are caused by interference (e.g. solar flares) and if your devices experience them often then either the hardware if faulty or you should look at some more screening from interference. We handle these in a "laissez faire" way; we have few enough devices and are few enough people for us to generally remember what happens. If we start seeing what we think are too many messages (e.g. more than one in some weeks) we pull statistics from the log archive. We currently have a single device (Sup720-10G) that logs an error about once or twice a year. It sits just beneath a box with almost the exact same configuration and that one doesn't log any errors. But since they are (so far) recoverable and rare we have done nothing yet. (Improperly seated cards might also be a cause for errors by the way.) -- Peter _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
