Hi,

Just would like to know some basic question regarding configuring my singlebox ESX host with multiple vswitch and two pNIC,

what's the definition or usage of Network Label and Port ID ? for VLAN yes I know what it is use for.

my goal here is to

1. create multiple vSwitch with many 4 VMs each on both vswitch and have it communicate between vswitch1 and vswitch0 somehow doesn't happening ? do I need to plug pNIC2 into the switch so the communication can/must travel through the networking cable back into my ESX?

2. how to force all Vmthe traffic in one vswitch to go into one VM that is running as router VM and then talk to the other vswitch router VM ? is it possible ?

Thanks.

a vSwitch Network Label is just that... a label to help you identify the portgroup.  You want to have your labels consistent from host to host when clustering; otherwise, vmotion, HA and such will fail to work properly.

Port ID is the default setting for Load Balancing...Route based on originating virtual port ID.

Vlan ID is the vlan tag #

If you want communication between vSwitches, you either need them connected physically through physical switching and routing(if using different networks) or bridge them with a VM that has a nic in each portgroup/vSwitch.  If you want all traffic in vSwitch0 to go through vSwitch1, then you would bridge it with a VM that is configured to route traffic and it's IP address in vSwitch0 would be the gateway for all VM's in vSwitch0.

Is that what you were looking for???

thanks for your reply mate, "then you would bridge it with a VM that is configured to route traffic and it's IP address in vSwitch0" --> so I must create a VM that have 2 vNIC and assign each Network Label on each vNIC as multihomed VM ?
