HP Virtual Connect 8Gb 24-port Fibre Channel Module for c-Class BladeSystem - Manual (Page 133)

Configuring the Virtual Connect domain using the CLI 133
The networks become members of the specified network access group in addition to all the previously
configured network access groups.
To modify the network access groups of an existing network, use the set network command:
>set network Net1 nags=NetGroup1,NetGroup2
The specified network now belongs to the specified network access groups and is no longer the member of
previously configured network access groups.
Creating an Ethernet network that uses network access groups
To create a network that is assigned to network access groups DatabaseNetGroup and AccessNetGroup,
use the add network command:
>add network Network1 nags=DatabaseNetGroup,AccessNetGroup
Adding uplink ports to an Ethernet network
To add uplink ports to an existing Ethernet network, use the add uplinkport command:
>add uplinkport enc0:1:1 network=MyNetwork
Modifying uplink port properties
To modify an uplink port that exists as a member of a network or shared uplink set, use the set uplinkport
command:
>set uplinkport network=Network1 speed=1Gb
Creating a shared uplink set
To create a shared uplink set, use the add uplinkset command:
>add uplinkset MyUplinkSetName
A shared uplink set identifies VC-Enet module uplinks that carry multiple networks over the same cable or set
of cables. In this case, each Ethernet packet carries a VLAN tag (IEEE 802.1Q) to identify the specific
network to which it belongs. On shared uplinks, the VLAN tags are added when packets leave the
VC-enabled enclosure and are removed when packets enter the enclosure. The external Ethernet switch and
VCM must be configured to use the same VLAN tag identifier (a number between 1 and 4094) for each
network.
Virtual Connect places no special restrictions on which VLAN identifiers can be used, so the VLAN IDs
already used for the networks in the data center can be used on these shared uplinks. To configure a shared
uplink set for VLAN tagging, obtain a list of the network names and their VLAN IDs.
A shared uplink set enables multiple ports to be included to support port aggregation and link failover with
a consistent set of VLAN tags.
Because VLAN tags are added or removed when Ethernet packets leave or enter the VC-Enet shared uplink,
the VLAN tags have no relevance after the Ethernet packet enters the enclosure.
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 outgoing
Ethernet packets are VLAN-tagged.
Displaying shared uplink sets
To display shared uplink sets, use the show uplinkset command:
