HP Virtual Connect Flex-10 10Gb Ethernet Module for c-Class BladeSystem - Manual (Page 95)

Configuring the Virtual Connect domain using the CLI 95
IMPORTANT: If you are deploying a server where VLAN tags will be used (added) on the server
itself, do not connect the server Ethernet port carrying VLAN-tagged traffic to a shared uplink set.
Identifying an associated network as the native VLAN causes all untagged incoming Ethernet packets to be
placed onto this network. Only one associated network can be designated as the native VLAN. All out-going
Ethernet packets are VLAN tagged.

Adding uplink ports to a shared uplink port set
To add uplink ports to a shared uplink port set, use the add uplinkport command:
>add uplinkport enc0:1:2 uplinkset=MyUplinkSetName
Creating a network that uses a shared uplink port set
To create a network that uses a shared uplink port set, use the add network command:
>add network MyNewNetworkName uplinkset=MyUplinkSetName vlanid=156
Server VLAN Tagging Support
With VC 1.31 and lower, each server port could be connected to a single virtual network. With v1.31 and
higher, each server port can be connected to multiple virtual networks, each using a unique server VLAN ID
for virtual network mapping.
This feature can be turned off or turned on by using the following command:
>set enet-vlan VLanTagControl=Tunnel
>set enet-vlan VlanTagControl=Map
If upgrading firmware to VC v1.31 or higher, this feature is disabled by default.
If Virtual Connect is set to map VLAN tags, 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.
>set enet-vlan VLanTagControl=Map SharedServerVLanId=true
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
