vswitch major problems.

[casit]

I have 2 NICS on my blade. One for a main ethernet switch(vmnic0) and also one for a new ethernet switch(vmnic1). I created a new vswitch1 on the vmnic1 adapter. This nic is on a totally seperate subnet than the rest of the network. My problem is this.

I can ping from ssh'ing to the server and pinging a device on the outisde of the new switch. And I can ping from the outside device to the esx service console which has an ip in this new range. And I can also ping from the serivce console to the vm in this new switch. However I can't ping from the vm to the outside device. Extremely frustrating and really don't know what the problem is since it all makes sense in my head but this problem has me spinnning in circles

Hi,

Check your VM Network adpater Network connection settings

VM is connected in the network or out of network..?

If its in the network then change Network connection settings and ping..

Hello,

Please provide a diagram, what you said is not all that clear. I interpret that you have:

subnet<->pSwitch<->pNIC0<->vSwitch0<->Portgroup0<-> SC
subnet<->pSwitch<->pNIC1<->vSwitch1<->Portgroup1<->VMs

You can ssh to and from your SC.

You can not reach the VMs? Are your VMs using static IPs? Or do you want it to use DHCP, do you provide this server? Are you trying to ping from the proper subnet?

Sounds like the VM portgroup is not setup or is wrong. Using the service console whic you can SSH into still see how everything is mapped.

esxcfg-vswitch -lSwitch Name Num Ports Used Ports Configured Ports MTU Uplinks

vSwitch0 64 9 64 1500 vmnic2,vmnic0

PortGroup Name VLAN ID Used Ports Uplinks

VM Network 41 5 vmnic0,vmnic2

This should identify what is connected to what.

From there you can maybe identify incorrect VLAN IDs etc. Once you have identified the incorrect settings you will can use some esx-cfg commands to resolve the problem.
