ESX4 VLAN Tagging + Broadcom M6220's + Cisco 3750's

Hello All,

I have a question.

I have a Dell M1000 chassis with a Dell Blade M600. I'm trying to use the software VLAN tagging in ESX to avoid putting VLANs on any of my switch ports. This way I can have several VLANs on the same ESX server out the same NIC.

VM NIC1 tagged in ESX with VLAN 20 -> vSwitch1-> M600 NIC #1 -> port G1 on M6200 -> port G17 on M6220 -> Port 9 on Cisco

So far, I have all 3 ports in trunking mode but it does not work. I'll paste my cisco config below and I've configured the M6220 via the web interface.

My cisco config is as follows, everything else is normal. I know I'm probably missing some things, I've seen people use native VLANs, vtp transparent, nonegotiate. Not sure if I need any of that.

They use the nonneogiate option on the ciscos but other than that I'm still not sure how to configure the M6220's

Still need more info 😕

Thank you Smiley Happy

Try a switch config like the one below....we use Cisco 6509s

interface GigabitEthernet3/1

description VMware - ESX_VM_TRAFFIC

switchport

switchport trunk encapsulation dot1q

switchport trunk native vlan 1 #set to your ESX SC vlan or any vlan not being used by a VM

switchport trunk allowed vlan 10,20,30 #VM VLANs

switchport mode trunk

no ip address

speed 1000

duplex full

spanning-tree portfast trunk

spanning-tree bpduguard enable

end

-C

Again.. I'm looking for help with the Broadcom M6220's.. there is very poor documentation that I can find on them. I was hoping someone had a similar setup.

Figured it out...

On the Cisco side..

interface Gigabitblah

switchport trunk encapsulation dot1q

switchport trunk native vlan 4000

switchport trunk allowed vlan 10,20,30

switchport mode trunk

switchport nonegotiate

spanning-tree portfast trunk

On the M6220 side..

interface ethernet 1/g1

switchport mode general

switchport general allowed vlan add 10,20,30 tagged

interface ethernet 1/g17

switchport mode trunk

switchport trunk allowed vlan add 10,20,30
