Michael, I totally missed the fact that reads don’t stress EEPROMs! <blush> Excellent point, and makes the vendor’s claim totally bogus. Probably just one employees claim, but the vendor should step up and fix the real problem. -mel

I have a vendor that does not support SFP DOM SNMP polling. They state this is due to EEPROM read life cycle. Constant reads will damage the SFP.
Complete and total garbage. Reading from EEPROM and Flash both DO NOT WEAR. It is the erase+write cycle that wears them. Further typical EEPROM life cycle is ~1M erase/write cycles. If you wrote it every minute you could conceivably wear it out in a couple years...but thats flat out not how it works. The EEPROM, if any, is not going to be used for statistics data....maybe fail counts of some kind, lifetime (hours) maybe...that sort of thing.
We SNMP poll SFP DOM from Cisco equipment without issue.
Not heard this one before. Trying to see if there is some validity to the statement. Thoughts?
