RackSwitch G8000: Application Guide
The G8000 can connect with a virtualization management server to collect
configuration information about associated VEs. The switch can also automatically
push VM group configuration profiles to the virtualization management server, which
in turn configures the hypervisors and VEs, providing enhanced VE mobility.
One virtual management server must be assigned on the switch before distributed
VM groups may be used. N/OS 6.8 currently supports only the VMware Virtual
Center (vCenter).
Assigning a vCenter to the switch requires the following:
• The vCenter must have a valid IPv4 address which is accessible to the switch
(IPv6 addressing is not supported for the vCenter).
• A user account must be configured on the vCenter to provide access for the
switch. The account must have (at a minimum) the following vCenter user privi-
leges:
– Network
– Host Network > Configuration
– Virtual Machine > Modify Device Settings
Once vCenter requirements are met, the following configuration command can be
used on the G8000 to associate the vCenter with the switch:
RS G8000(config)# virt vmware vcspec <vCenter IPv4 address> <username> [noauth]
This command specifies the IPv4 address and account username that the switch
will use for vCenter access. Once entered, the administrator will be prompted to
enter the password for the specified vCenter account.
The noauth option causes to the switch to ignores SSL certificate authentication.
This is required when no authoritative SSL certificate is installed on the vCenter.
Note: By default, the vCenter includes only a self-signed SSL certificate. If using
the default certificate, the noauth option is required.
Once the vCenter configuration has been applied on the switch, the G8000 will
connect to the vCenter to collect VE information.
Once the vCenter is assigned, the switch will periodically scan the vCenter to collect
basic information about all the VEs in the datacenter, and more detailed information
about the local VEs that the switch has discovered attached to its own ports.
The switch completes a vCenter scan approximately every two minutes. Any major
changes made through the vCenter may take up to two minutes to be reflected on
the switch. However, you can force an immediate scan of the vCenter by using one
of the following ISCLI privileged EXEC commands:
RS G8000# virt vmware
-or-
RS G8000# show virt vm
(Scan the vCenter)

(Scan vCenter and display result)
