Symbol Errors are related to the L1 signaling. As you know, there will be some coding used such as 4B/5B. If there is a problem with this coding, you will see that the symbol and sequence errors increase. These errors are seen when the Mac sees "invalid" symbols. In most cases, this is a physical problem - Gbics, fiber, etc. These errors also increment when the link is not up because the Mac isn't syncronized and receives noise.
So you will want to check the cabling, the GBICs, if the cables are inserted correctly, etc.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
