Hi guys,I have been working with IPTV for one year, so, all switch involved in this topology are x460, in this network I have mpls and vr created, nonetheless the multicast traffic is going through a specific VR with pim enabled.Everything is working properly, where on the main switch I have 2x460 in stack and two 10g ports going to other switch and 6 gigabit port going to another x460, in both case I have LACP enabled.
So, the curious situation that sometimes I can see some channels get a little bit checkered for some seconds, once it means that some dropped packed happened, but it just happens over traffic that is going through gigabit ports.In order for trying to solve this issue, we changed the SFP, optical patch cords, added more giga ports, increase the buffer ports to 100%, and with these stuff we could improve the transmission but not eliminated it in definitive.what we could notice that, sometime is still being logged some drop packets in these gigabit interfaces, where is causing this bad experience.I have tried to do a lot of thing to finished this dropped packets off. I could decrease the number of this incidents but not eliminated.I've been thinking that it could be the cpu process when using a gigaport where these are shared with the main cpu, different of 10g modules where they have a specific module to process all over the traffic.
Would someone get the same experience using x460 (not G2)? how would you solve this issue?
Tks
