We are facing some multicast issue in our metro network, some time some fof the channels are getting freezed, when I checked the source router, i am not getting any porbelm, the VLC works fine, we have aroung 30 Nos of HD channel in the network and around 600 FTA channel also, I also notice the most of our ME3750 and ME3400 is having platform drops.Below is our topology.
I am not able to isolate the issue, is it core or aggrigation router side isue as i am not getting any logs over there and there is no interface erros also.
Metro-------(G0/1)ME3400(f0/2)-------CPE---------STB----------TV
Metro-------(G1/1/1)ME3750(f1/0/2)-------CPE---------STB----------TV
is this normal, or do we need to take with SR.
ME3750

Hi,
ME3400 and ME3750 are not famous for big port buffers.
You might try do some tuning but before that you can do a simple test to see if the problem is caused by the depletion of TX buffers due to bursty traffic.
From the topology I see that you have mismatch speed between ingress and egress ports. This is normally cause n.1 for output drops on these platforms.
Can you temporarely configure 100Mb speed on ingress ports to see if drops cease?
After that we will see if we can continue here or if it is better for you to open a TAC SR.
regards,
Riccardo

Hi Saji,
maybe I did not make myself clear enough.
You don't need to lower the speed of the Fast port (which cannot be above 100Mb/s anyway) but you need to remove the oversubscription between ingress and egress. Your Gi1/1/1 and Gi1/1/2 are likely working at 1000Mb/s which is causing oversubcription wehn traffic go to Fast ports. You need to lower to 100Mb/s the Giga port if possible as a test.
Anyway go for a SR for a TAC engineer to guide on the possible tuning you can apply.
