pixelation on Multicast VIDEO -CISCO 3850

hisham
Level 1
Level 1

Hello Guys,

 

i am using Cisco Catalyst 3850 as my IPTV core switch (connected to 1Gig Fibre from ISP) to receive multicast streams to my network. i am facing freezing and VLC error message shows picture too late to be displayed when connected directly to the Switch. can you please guide me to fix this? (it was working very well for past 8 months, recently started pixelating and it is very annoying for customers)

what multicast the stream itself? something local to your network or something at the ISP end?  what sort of bandwidth are we talking about 1080p? 720p?  is not local, is there any QoS? and or contention?

Please remember to rate useful posts, by clicking on the stars below.

this is SPTS live channels from ISP on 1G Single mode Fiber.(with 1G SFP on switch side). there are 1080p and 720P channels and  total bandwidth of channels is around 530MBps.

the switch is dedicated for IPTV only and no specific QoS config

LAST UPDATE 3500 msecs AGO

 

Those stats show a 56.8% average load across 5 minutes.

Some video codecs can have highly variable bandwidth demands in short time frames. If that's true for yours, it's possible you're exceeding 100%, in bursts, which could be causing the lost of some packets. You would need to check for interface drops on all upstream interfaces.

If doing that's difficult, you could first try setting the load interval to 30 seconds, and then tracking/plotting the average utilization. 30 seconds is still a very, very (very) long interval looking for micro bursts, but it might show a more variable load, which would confirm the codecs are variable in their bandwidth needs.

thank you for the feedback,

 

running config has load-interval 30 under the IPTV VLAN.

Hello,

 

I have seen instances where buffer tuning can help resolve VLC issues. Can you post the output of 'show buffers' ?

Ah, but your earlier posted stats for g1/1/2 appears to have a load interval of 5 minutes.

 

BTW, VLAN interfaces shouldn't be choke points.  Generally, for drops, it's physical interfaces you need to concern yourself with.

 

As to the command to show drops, it depends on the device.  For routers, generally a show interface will list drop stats, for for some switches, you need to use commands to list stats at a lower hardware level.

Hello,

 

in addition to Dennis' remarks, what is VLC running on locally (e.g. Windows 10), and what else do you have installed on your PCs (that is, what other software) ? Do the PCs have multiple NICs ?

You mention an ISP. Your multicast is transiting some form of 3rd party link? If so, assuming nothing else has changed on your end, the 3rd party's network may have changed in a way that impacts your video.

Your messages appear to show excessively delayed packets. That's generally due to insufficient bandwidth for the video stream, which is often, or might be, guaranteed by QoS. What you would want to do, if find where your video packets are being delays, and mitigate that.
