Command Syntax and Usage
virt vmgroup <1‐4096> stg <1‐128>
Assigns the VM group to a Spanning Tree Group (STG).
Command mode: Global configuration
[no] virt vmgroup <1‐4096> tag
Enables or disables VLAN tagging on ports in this VM group.
Command mode: Global configuration
virt vmgroup <1‐4096> validate {basic|advanced}
Enables MAC address spoof prevention for the specified VM group.
basic validation ensures lightweight port‐based protection by

cross‐checking the VM MAC address, switch port and switch ID between
the switch and the hypervisor. Applicable for "trusted" hypervisors, which
are not susceptible to duplicating or reusing MAC addresses on virtual
machines.
advanced validation ensures heavyweight VM‐based protection by

cross‐checking the VM MAC address, VM UUID, switch port and switch ID
between the switch and the hypervisor. Applicable for "untrusted"
hypervisors, which are susceptible to duplicating or reusing MAC
addresses on virtual machines.
The default setting is disabled.
Command mode: Global configuration
no virt vmgroup <1‐4096> validate
Disables MAC address spoof prevention for the specified VM group.
Command mode: Global configuration
virt vmgroup <1‐4096> vlan <VLAN ID (1‐4094)>
Assigns a VLAN to this VM group. If you do not assign a VLAN to the VM
group, the switch automatically assigns the first unused VLAN when adding a
port or a VM to the VM Group.
Note: If you add a VM profile to this group, the group will use the VLAN
assigned to the profile.
Command mode: Global configuration
[no] virt vmgroup <1‐4096> vm {<VM MAC address index (0‐4095)>|
|<MAC address>|<UUID>|<name>|<IP address>}
Adds or removes a VM to/from the VM group. Enter a unique identifier to
select a VM. The UUID and name parameters apply only if Virtual Center
information is configured (virt vmware vcspec). The VM index number is
found in the VM information dump (show virt vm).
Note: If the VM is connected to a port that is contained within the VM group,
do not add the VM to the VM group.
