vCenter.</para></entry>

<entry><para>The default value assumed would depend upon the type of virtual switch.

Defaults values are as follows. vSwitch0 if type of virtual switch is "VMware

vNetwork Standard virtual switch" dvSwitch0 if type of virtual switch is "VMware

vNetwork distributed virtual switch" epp0 if type of virtual switch is "Cisco Nexus

1000v distributed virtual switch</para></entry>

<entry><para>This field would be used for only public traffic as of now. In case of guest traffic this

field would be ignored and could be left empty for guest traffic. By default empty

string would be assumed which translates to untagged VLAN for that specific traffic

type.</para></entry>

<entry><para>Type of virtual switch specified as string</para></entry>

<entry><para>Possible valid values are vmwaredvs, vmwaresvs, nexusdvs. Each translates as follows.

"vmwaresvs" represents "VMware vNetwork Standard virtual switch" "vmwaredvs"

represents "VMware vNetwork distributed virtual switch" "nexusdvs" represents "Cisco

Nexus 1000v distributed virtual switch" If nothing is specified (left empty) that

means zone level default virtual switch (based on value of global parameters) would

be assumed. Following are the global configuration parameters. vmware.use.dvswitch -

This should be true to enable any kind (VMware DVS / Cisco Nexus 1000v DVS) of

distributed virtual switch in cloudstack deployment. If this is false that means

default virtual switch in that cloudstack deployment is "standard virtual switch"

only. vmware.use.nexus.vswitch - This parameter would be ignored unless

"vmware.use.dvswitch" is true. Set this to "true" to enable Cisco Nexus 1000v

distributed virtual switch in a cloudstack deployment.</para></entry>
