IPTV problem - image blocks

[lmferreira]

Hi.

Sorry for not replying sooner but it has been impossible to me.

I send in attachment the 'sh tech all' of our core

Now goes the 'sh tech all' file of the switch that has plugged into the b19-b21 TV boxes and in the ports B23 and B24 the IPTV servers.

Thanks for all your help and attention to this case.

Hi people.

Can you please reply me? I really need your help and i don't know what to do more.

Thank you!

Looking at the counters for port B20:
Rates (5 minute weighted average) :
Utilization Tx : 80.58 %

I would start by trying to do something about that: change the interface settings, then do a "show int b20" to baseline the counters. Wait 5 minutes then "show int b20" again.

My guess would be that setting the port to 100 half duplex would improve things. You want a configuration where the FCS Rx counter isn't increasing. As Rick noted earlier, full duplex *at both ends* would be best but it's more important that they are consistent.

Indeed, FCS errors are "Bad News (tm)" and suggest a fundamental problem - either a duplex mismatch, bad/marginal port or bad/marginal cable.

Hi,

Just came across this thread, i'm having very similar problems with one of my clients. Did you ever pinpoint the cause of this issue?
