Adding uplink ports to a shared uplink set
To add uplink ports to a shared uplink set, use the add uplinkport command:
>add uplinkport enc0:1:2 uplinkset=MyUplinkSetName
Creating a network that uses a shared uplink set
To create a network that uses a shared uplink set, use the add network command:
>add network MyNewNetworkName uplinkset=MyUplinkSetName vlanid=156
Creating multiple networks that use a shared uplink set
To create multiple networks that use a shared uplink set, use the add network-range command:
>add network-range UplinkSet=SUS1 VLANIds=
Server VLAN Tagging Support
Each server port can be connected to multiple virtual networks, each using a unique server VLAN ID for virtual
network mapping.
The translation of Server VLAN tags to internal network VLAN and again to external data center VLAN tags,
and the reverse, on incoming and outgoing frames can result in a configuration where the server VLANs
might not match the external VLANs used on uplinks. To avoid this scenario, the server connections can be
forced to use the same VLAN mappings as the shared uplink sets. Setting the value to "true" restricts the server
network connections to be selected from a single shared uplink, and the VLAN ID cannot be modified:
>set enet-vlan SharedServerVLanID=true
Setting the value to "false" enables you to select any VC Ethernet network for the server Ethernet connections,
and VLAN ID mappings can be modified to ensure uniqueness:
>set enet-vlan SharedServerVLanID=false
When using mapped VLAN tags, the overall link speed can be controlled as follows:
>set enet-vlan PrefSpeedType=Custom PrefSpeed=500 MaxSpeedType=Custom
MaxSpeed=2500
VLAN Capacity
Virtual Connect imposes certain limits on the number of networks (VLANs) in the domain and the server
connections carrying multiple VLANs. In a VC domain that does not contain legacy (1/10Gb) VC Ethernet
modules, these restrictions can be relaxed to provide support for more VLANs and enhance the flexibility of
mapping VLANs to server connections. When VCM detects that no legacy modules are present in the
domain, it enables the selection of a new domain mode that expands the VLAN capacity. The increase in the
number of VLANs per domain, in addition to the flexibility of allocating VLANs among the server connections
for a physical port, provides you with more options when configuring a Virtual Connect environment.
