I would say lets start with one side and get communication working between the two computers plugged into the same stack at RTTMOACCESS01. The port settings for 1/01 and 2/01 look good with both in access mode for VLAN 10. What IP addresses and subnets are you assigning to the computers? The connection from the 5548 stack to the Force 10 stack also appear to not be in a LAG, when we run two connections like that and they are not in a LAG, we are creating a loop and one connection will go into a blocking state.  For the connections from the 5548 to the force 10 I suggest turning those into a LAG. The command would look similar to this. console> enable console# configure console(config)# (config)# interface tengigabitethernet 1/0/1 console(config)# port-group 1 mode auto console(config-if)# exit console(config)# Do the same for Te2/0/1 Then we configure that LAG to configure it, and I would like to try using Trunk mode instead of General mode. console(config)# interface port-channel 1 console(config-if)# switchport mode trunk console(config-if)# switchport trunk allowed vlan add 10,20,30,40,50 tagged The same would need to be done for the Force 10 switch. Te0/46,1/46 into a LAG Te0/47,1/47 into another LAG Set to Trunk and allow the VLANs across the trunk. Lets look into those settings and see if we can make any progression. Thanks
In the next few months we'll be replacing our network gear.  I was able to get my hands on the new gear early, and though I'm not traditionally a network guy, the project has been given to me, and I starting to play around.  The first thing I wanted to work on was setting up VLANs.  I've set the switches up like the image below: [IMAGE] When I IP all the connected PCs on the same subnet, and apply VLAN10 to their respective ports, they are not pingable within the same stack or between stacks.  My basic understanding is that they should be, shouldn't they?  Am I missing something in my understanding of VLANs or is there a problem with my configs?  I've posted the configs below.
