I had some problems configuring the VMware distributed switches v5.5 in conjunction with a SA SPE and VLANs on the internal interface.
The Juniper document "AppNote-Virtual-SA-appliance-with-VLAN1.pdf" only provides information for older VMware versions and I can´t find a guide for VMware 5.5.
So after some time, I found the following solution:
- the VLAN configuration on the VMware distributed switch should look like VLAN Type = VLAN Trunking, VLAN trunk range = 0, 10,30, where 0 = the untagged internal interface of the SPE and 10,30 are two tagged VLANs
- on the physical Cisco switch I configured the native vlan on each port connected to the vSphere Servers. ( switchport trunk native vlan xyz )
That´s all, without additional or dedicated ports for the SA SPE.
