I am currently having an issue on a large home network that I need some help with. Just as a preface I have just acquired my CCNA but my experience in troubleshooting real world scenarios is nill. So I am hoping someone could nudge in the direction of good information to get me started in the troubleshooting process.
Here is the problem, at the core of the network we have a ASA 5505 that serves as the DHCP server. The router intermittentantly starts droping packets on VLan1, which is the interface that serves the IPs. Vlan2 is the outside interface which acquires its IP via DHCP. At the router even when packets are being dropped on the inside interface I can get out fine. e.g. I can ping outside hosts from the outside interface when no traffic is getting through from the inside. I will attach my config here along with a 'sho int vlan1 detail' to demonstrate.
Start 'sho int vlan1 detail'
Interface Vlan1 "inside", is up, line protocol is up
The switch ingress policy drops are caused by improperly tagged vlan packets I believe. This shouldn't have anything to do with speed/duplex if I understand correctly. Please correct me if I am incorrect.
The overall problem is that the users experience their internet connectivity basically drop during the times packets are being dropped on VLan1. Could the amount of filtered packets cause connectivity for everyone else to come to a halt. And also is there a way for me to monitor the packets that are being filtered so I can determine if they are all coming from the same host.
