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
Hardware is EtherSVI
MAC address 001f.ca58.ee2f, MTU 1500
IP address 10.10.40.1, subnet mask 255.255.0.0
Traffic Statistics for "inside":
2600952 packets input, 224101620 bytes
2394181 packets output, 2628251475 bytes
539541 packets dropped
1 minute input rate 262 pkts/sec, 16150 bytes/sec
1 minute output rate 437 pkts/sec, 535764 bytes/sec
1 minute drop rate, 352 pkts/sec
5 minute input rate 164 pkts/sec, 8460 bytes/sec
5 minute output rate 275 pkts/sec, 335720 bytes/sec
5 minute drop rate, 278 pkts/sec
Control Point Interface States:
Interface number is 1
Interface config status is active
Interface state is active
So I just am a little clueless on how to start the troubleshooting process. I would sincerely appreciate any mentoring or guidance.
Also please be gentle, I am really new to this.
