We have a pair of Nexus 7K. we went in with the first 7K (as the second switch was supposed to be placed in another MDF and that was not ready) and configured about 60 edge switches. then once the other MDF was ready, we configured the second Nexus 7K, vPC, HSRP etc for all the vlans (2 vlans per edge switch). one of these 2 vlans on every switch has CCTV cameras sending the video to the central storage. once we configured the second Nexus, we are noticing some issues with the camera feed from a couple of edge switches only. All the other edge switches have absolutely no issues. what we are noticing is that the feed from the cameras connected to these 2 switches if hanging for about 4-5 seconds before it comes back up. however this keeps on happening evry 8-10 mins.
can anyone help me to find out what could be the issue?
