There's Heaven, where IT has an unlimited budget and management understands the reasoning you state below. And there's reality, where IT is a cost center, has to beg for every penny spent, and often times has to make do with what they have. Besides, how much fun would it be if everything was clear-cut and easy? Jason On 3/6/2012 11:53 AM, david peahi wrote:

Why don't you replace the Dell switches with Cisco 3560s, and that way you are working with a single implementation of the IEEE 802.1q trunking standard? I think the very existence of this email thread proves that much time and effort is wasted in the attempt to seamlessly interoperate devices from multiple vendors. In this email thread alone I counted 2 CLI's to be learned, 2 tech support organizations to call, and 2 hardware types to spare.

I hope everyone is having a better workday so far than I am.
I am trying to clean up the network for the Hospital I work for, and part of that is creating two VLAN's for two separate subnets on our network. Before, it was not separated by VLANs. We are also replacing our aged Juniper firewall with an ASA.
I'm very new to VLAN's, so I am hoping this is something simple that you guys can help me out with.
We have two switches that do not seem to be passing VLAN traffic. The two switches are a Dell Powerconnect 5324& a Cisco 3560G. The Cisco switch appears to be functioning fine, but the Dell switch is only passing traffic to the Cisco that is on the default untagged VLAN1. Our second VLAN is not getting passed to the Cisco at all, I am not seeing any packets tagged with the particular vlan in Wireshark.
I have Port 1 on the Dell switch connected to port 29 on the Cisco switch, and port 1 on the Cisco switch connected to the ASA.
I have the following config on the relevant ports on the Cisco switch:
interface GigabitEthernet0/1 description ASA 5505 switchport trunk encapsulation dot1q switchport mode trunk
interface GigabitEthernet0/29 description Radiology Switch switchport trunk encapsulation dot1q switchport mode trunk
Here is the config for the Dell switch:
interface ethernet g1 speed 1000 duplex full exit interface ethernet g2 speed 1000 duplex full exit interface ethernet g3 speed 1000 duplex full exit interface ethernet g4 speed 1000 duplex full exit interface ethernet g5 speed 1000 duplex full exit interface ethernet g7 speed 1000 duplex full exit interface ethernet g9 speed 1000 duplex full exit interface ethernet g10 speed 1000 duplex full exit interface ethernet g12 speed 1000 duplex full exit interface ethernet g14 speed 1000 duplex full exit interface ethernet g15 speed 1000 duplex full exit port jumbo-frame interface ethernet g1 switchport mode trunk exit interface ethernet g24 switchport mode trunk exit vlan database vlan 12,22 exit interface range ethernet g(2,4,7,12,14-15) switchport access vlan 12 exit interface vlan 12 name Radiology exit interface vlan 22 name Guest exit interface vlan 1 exit
Anyone have any ideas or pointers? Is there more information that I need to provide? Vlan1 works just fine, of course. It is Vlan 12 that is not working. Everything on the Dell switch is communicating with each other just fine on the same subnet.
