Hello, The bladecenter was initially setup by a company and allows me to only create VM's from Vlan 2. The issue is that I am out of Ip's in that vlan and I wanted the ability to use another address space for the VM's. I've already created a new vlan 20. Here is the current config of the switch. All I've added to these configurations from before was sw trunk allowed vlan add 20 Main Switch CISCO 4500 interface Port-channel1 switchport switchport trunk encapsulation dot1q switchport trunk native vlan 3 switchport trunk allowed vlan 1-3,20 ! ! interface GigabitEthernet5/39 description BLADECENTER-sw2-p17 Trunk Port switchport trunk encapsulation dot1q switchport trunk native vlan 3 switchport trunk allowed vlan 1-3,20 channel-group 1 mode on ! interface GigabitEthernet6/2 description BLADECENTER-sw2-p17 Truck Port switchport trunk encapsulation dot1q switchport trunk native vlan 3 switchport trunk allowed vlan 1-3,20 channel-group 1 mode on ! Switch config - Bladecenter sw1 vlan 2 server vlan 3 WAN vlan 20 server2 interface Port-channel1 switchport trunk native vlan 3 switchport trunk allowed vlan 1-3,20 interface GigabitEthernet0/17 switchport trunk native vlan 3 switchport trunk allowed vlan 1-3,20 macro description cisco-switch channel-group 1 mode on ! interface GigabitEthernet0/18 switchport trunk native vlan 3 switchport trunk allowed vlan 1-3,20 macro description cisco-switch channel-group 1 mode on blade switchport where host is contained interface GigabitEthernet0/9 description blade9 switchport trunk native vlan 2 switchport trunk allowed vlan 2,20 switchport mode trunk. End result is I can't use any vlans from that new range. I've been reading and thinking there are configuration changes I need to make on the ESX server itself with vlan tagging and such. Nothing like that is setup currently. Thanks in advance.
