Some Cisco certified resellers get greedy, buy the counterfeit stuff for pennies on the dollar, and then resell it a 'great discount.' All of this violates their Cisco reseller agreement, but greed seems to win the day. That seller has plenty of other 'Cisco' equipment for sale at equally impressive discounts compared to legit gear:ДЄll of this stuff ends up in secondary channels like Ebay.

This SFP is priced for $20 on that site (a real SFP from a legitimate Cisco reseller lists for hundreds). This photo was taken from a reseller located in Asia.

Here's a photo of an SFP that appears to be counterfeit: We shipped the questionable SFPs to Cisco Brand Protection Labs, and they verified all were counterfeit. The initial letter changes (we saw some begin with H, and P).ДЄlso, in restrospect, we realized the counterfeit devices had a far higher failure rate than real Cisco. This is very typical, and how we identified hundreds of bogus SFPs that were in production. Note the serial number 'H11F797' is not in the standard (longer) format. The 1st 3 letters are the factory, the next 4 numbers are a date code, and the last 4 letters/numbers are a unique ID.Д«ATTY-C3750-1# show idprom interface gigabitEthernet 1/0/1 The key is the serial number (bolded), which is in the standard Cisco format for SFPs: 3 letters, followed by 4 numbers, followed by 4 letters/numbers. Once we investigated, there was a clear pattern on the counterfeit gear, regarding bogus serial numbers.ДECKARD-C3750-1# show idprom interface gigabitEthernet 1/0/1 The counterfeit gear had a label/serial number on the device, but no serial number on the bag or box. Cisco is usually diligent on labeling: the serial number on the device matches the number on the bag (or box). The Cisco logo used was several generations old. We initially detected them due to shoddy packaging: labels that smear, cheap boxes, etc. Our investigation showed we received them from a number of sources (all Cisco registered resellers), including a Cisco Gold partner. Our biggest counterfeit problem was with SFPs and GBICs.
