Grimers wrote:Hi billion_fan,

The upstream ES and now SES counters on both downstream and upstream are broken. The upstream ES counter seems to go up even when there's nothing to cause it and sometimes (on both downstream and upstream) when there's only a few CRC's (say 2) in an ES, it reports it as a SES (AFAIK, 9 + CRC's make an SES). Also, sometimes when there are more than 9 CRC's in an ES (in this example 12) it just reports it as an ES not SES.

I hope I've explained it ok, as I've noticed I've mentioned "ES" and "SES" several times in the previous paragraph.

Here's a screenshot from the telnet interface:



Thanks!

I'll check with our engineers
