RackSwitch G8000: Application Guide
Before you configure VMready features, you must first define whether ports are
connected to servers or are used as uplink ports. Use the following ISCLI
configuration command to define a port as a server port:
RS G8000(config)# system server-ports port <port alias or number>
Ports that are not defined as server ports are automatically considered uplink ports.
VEs, as well as switch server ports, switch uplink ports, static trunks, and LACP
trunks, can be placed into VM groups on the switch to define virtual communication
boundaries. Elements in a given VM group are permitted to communicate with each
other, while those in different groups are not. The elements within a VM group
automatically share certain group-level settings.
N/OS 6.8 supports up to 32 VM groups. There are two different types:
• Local VM groups are maintained locally on the switch. Their configuration is not
synchronized with hypervisors.
• Distributed VM groups are automatically synchronized with a virtualization man-
agement server (see
Each VM group type is covered in detail in the following sections.
The configuration for local VM groups is maintained on the switch (locally) and is not
directly synchronized with hypervisors. Local VM groups may include only local
elements: local switch ports and trunks, and only those VEs connected to one of the
switch ports or pre-provisioned on the switch.
Local VM groups support limited VE migration: as VMs and other VEs move to
different hypervisors connected to different ports on the switch, the configuration of
their group identity and features moves with them. However, VE migration to and
from more distant hypervisors (those not connected to the G8000, may require
manual configuration when using local VM groups.
Configuring a Local VM Group
Use the following ISCLI configuration commands to assign group properties and
membership:
RS G8000(config)# virt vmgroup <VM group number> ?
key <LACP trunk key>
port <port alias or number>
portchannel <trunk group number>
profile <profile name>
stg <Spanning Tree group>
tag
vlan <VLAN number>
vm <MAC>|<index>|<UUID>|<IPv4 address>|<name>
vmap <VMAP number> [intports|extports]
