G8264CS Application Guide for ENOS 8.4
When VMready is enabled, the switch will automatically discover VEs that reside
in hypervisors directly connected on the switch ports. Enterprise NOS 8.4 supports
up to 2048 VEs. Once this limit is reached, the switch will reject additional VEs.
Note: In rare situations, the switch may reject new VEs prior to reaching the
supported limit. This can occur when the internal hash corresponding to the new
VE is already in use. If this occurs, change the MAC address of the VE and retry the
operation. The MAC address can usually be changed from the virtualization
management server console (such as the VMware Virtual Center).
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:
system server-ports port
RS 8264CS(config)#
Ports that are not defined as server ports are automatically considered uplink
ports.
VEs, as well as switch server ports, switch uplink ports, static LAGs, and LACP
LAGs, 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.
ENOS 8.4 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
management server (see "Assigning a vCenter" on page
Each VM group type is covered in detail in the following sections.
Note: VM groups are not supported simultaneously on the same ports as vNICs
(see Chapter 14, "Virtual NICs").
