Two Procurve 4108GLs, ip routing and packet loss
First post but this appears to be a great forum so I hope to participate more...
Here is my problem: I have two procurve 4108GLs that are connected by fiber. They both have the latest firmware. One of them (A) has 2 vlans. Vlan1 is the default with a subnet of 192.168.2.0/24. Vlan2 has a subnet of 192.168.1.0/24. The switch is routing between the vlans successfully. Switch B has the default vlan1 with a subnet of 192.168.2.0/24. The switches are connected via the fiber on subnet 192.168.1.0/24. There is no other configuration. Everything appears to work fine. However, under high load I start loosing packets going from vlan1 on switch B (192.168.1.0/24) to vlan1 on switch A (192.168.2.0/24). I do not loose packest on swtich A going from vlan1 to vlan2. I do not loose packets going from vlan1 switch B to vlan2 switch A.
The vlans shouldn't matter since switch B is basically an expensive unmanaged switch. Can the routing on switch A just be overloaded? I see ~40% cpu average. But why does switch A vlan1 to vlan2 have no issues then? Do the vlans matter even if I am not passing any info?
Any insight would be greatly appreciated.
