PowerConnect 6024 - L2 Switch Problems
I'm trying to configure the ports on a Dell PowerConnect 6024 to act like a simple layer 2 switch. I've never used Dell switches before so I may just be missing something simple.
I've created VLAN 100, set all ethernet ports to be access ports, assigned them to the new VLAN 100, and set the ethernet ports to be 802.1x force authorized. I also tried disabling spanning tree to see if that was causing the problem.
I've connected two devices on g/1 and g/2, one with IP address 100.64.2.1 and the other with IP 100.64.2.2. I assigned the switch 100.64.2.3 later for debugging purposes.
I can ping both other devices from the switch (with usually 75% loss!), but I cannot ping from the other devices to another device (not the switch). Pinging the switch from any other device does work (again with near 75% loss).
The other devices are known-good with my Cisco switch, so do I have a bad PowerConnect switch or am I missing something?
Here is my configuration:
console# show running

I am using two Windows 7 Pro laptops with Windows Firewall disabled and static IPs set on both to the same subnet. I added flow control and port security just to try to get it working (I have removed them now), as I wasn't sure what the defaults were. When I enable spanning tree, the output of the spanning tree command is:
console# show spanning-tree active
Spanning tree enabled mode RSTP
Default port cost method: long
Root ID Priority 32768
Address 00:15:c5:2a:f3:fd
This switch is the root

The port counters command is:

I have tried updating the firmware to 2.0.0.19, and that did not solve any problems. I am currently running 2.0.0.19, when I ran the above commands.
console# show version
SW version 2.0.0.19 ( date 05-May-2008 time 16:33:30 )
Boot version 1.0.0.13 ( date 13-Aug-2003 time 15:28:31 )
HW version 00.01.64

I tried setting the ports to force 1000/full duplex with no change. I have swapped cables and these are known-good with another switch.

Yes, if I direct connect the laptops together or through another switch, both of them can ping each other. No anti-virus besides Windows Firewall is running, and Windows Firewall is disabled.

I moved one laptop to port g24 and moved the second to g23, to my surprise, the pings worked! I then went and did a port-by-port test, and it appears only ports 15-24 work on my switch. All the other act like they are working (linkup, stp forwards etc.) but I cannot pass any traffic.
I'm not sure what else besides a hardware problem causes this with the default configuration.
