ESXi 4.1 Trunking Configuration C210 M2

[DaveX4285_2]

So currently I am installing ESXi 4.1 on a C210 M2 series server. The basic install is completed and I am configuring the networking. I have two VLANs 10.1.152.0/24 (VLAN 152 Voice) and 10.1.153.0/24 (VLAN 153 Mgmt). The trouble I am having is I am unable to set up the trunk ports between the 2 LOM ports on the server and the 3750 switch. The management IP address of the ESXi host is 10.1.153.11 and is VLAN ID 153 but when I set the 2 switchports with the configuration below it does not work. But if I set the switchports to access and remove the VLAN ID from the ESXi management interface things come right back up. I am sure this is something simple. What needs to be done so I can trunk VLANs 152,153 to the ESXi host? Thanks greatly...

You havent configured ESXi for dot1q trunking it appears, he cannot read those tags, proven by removing the tags on the switch side and it works....setting 4095 as vlan id in vmware allows all vlan tags

You have configured  the 3750 to create a port channel.  I will assume you are using the standard vSwitch.  You will also need to configure vSwitch to perform IP hashing.  This is not a default setting.

As a test, i would recommend the following:

- Use two trunks rather than a port channel (remove your port channel configuration).  By default when two links are added to the vSwitch, ESX will load balance based on virtual portID.  All traffic from single VM will transverse a single link.

Sorry didnt see the port channel, aside from the tagging needing lined up ensuring you are accepting yge rags since you are sending them on switch. Then ensure you remove them as needed meaning that if you send them tagged to a guest make sure they are able to do so. Sending to guest is not a great idea use trunks and tag to host but remove with port groups. That said REMOVE rhe port channel and make sure your trunking is working. No need to port channel at all in fact you are just complicating things. VMware host is seen as a single host with many uplinks. Mac handling and load balancing will be taken care of by ESXi like a port channel is configured. You start adding po's then you have to line up hashing algorythms on each side and get LACP interoperavility, in your config no port channel needed, try it and you will see my friend.
