Just wanted to say a quick thank you to everyone who chimed in. Like I thought, it turned out to be something very simple and routine. I had not added the vlan to the Cisco switch. I had added it during testing, but I removed all testing config from the switch before I went to vlan's and did not add it back. On top of that, right before I saw the message to run sh vlan, I attempted to upgrade the firmware on the Dell switch and followed Dell's instructions to the T, but it appears that the switch is now non-functional. It is in a continuous reboot cycle and I can't even get anything over the console. Thankfully I had another switch ready and swapped it out and we are running strong with vlans. Again, thank you so much for all of your help, and hopefully one day I will be at the level to help someone else out on here.
