Sporadic Ping Issue

Hi Everyone,

So I had this problem yesterday.

But that was all because I was trying to troubleshoot this problem.

I have 4 devices on 2200's that will ping for a bit then just stop. Randomly it would be talking for 5 minutes then turn off. And I guess I need help troubleshooting what the problem is.

Connection Layout: 5406->4300 Virtual Chassis->2200 Virtual Chassis->Devices (10.4.10.X)

5406 config

trunk C21 trk17 trunk <----- Link to 4300
vlan 4
   name "LES Data"
   tagged Trk17
   ip address 10.4.0.1 255.255.0.0

   ip helper-address 10.2.1.17
   ip helper-address 10.2.1.21
