I have two switches in my network. The main is a Cisco 540-48. I have connected my workstation to this switch and was able to set up its IP address on our subnet.
The second switch is a Dell Powerconnect M6348. This is a switch in a blade chassis. In the past I have had this switch connect to other switched and it has worked fine and all workstations can see the servers that are connected via the Dell switch.
The problem is that I can't get traffic to flow from the Dell to the Cisco and I'm not sure why. I have tried connecting the Dell switch to the trunk ports and also the regular ports. The issue could be that the Cisco says the trunk ports are VLAN 1. However, when I try to set one of the ports on the Dell as a trunk, it accepts it, but I cannot set the VLAN number, the option is disabled. Is this supposed to be on or is something wrong?
