HP Virtual Connect 1.10Gb-F Ethernet Module for c-Class BladeSystem - Manual (Page 47)

Installation 47
Following is an example of a single network mapped to four external uplink ports.
Network Uplink port set
Production_Network { Enclosure1:Bay1:Port1
Enclosure1:Bay1:Port2
Enclosure1:Bay2:Port1
Enclosure1:Bay2:Port2 }
In this example, the ports from Bay 1 could be connected to one external switch, and the ports on Bay 2
could be connected to a second switch. If the external switches support link aggregation, then this
configuration would provide an active 2-Gb link to one switch and a standby 2-Gb link to the other.
To make Virtual Connect Manager aware of individual network connections, see "Define Ethernet
Network screen (on page 103 )."
Mapping multiple networks to a single, shared external uplink port
The network administrator can choose to reduce the number of cables between the Virtual Connect
enclosure and the data center switches by mapping multiple networks to a single, shared uplink port. In
this case, a network is not just mapped to an uplink port, but to a VLAN on that port. This configuration
requires VLAN tags to be added to each packet as it leaves the Virtual Connect domain and that packets
entering the Virtual Connect domain be tagged (the VLAN tag is stripped from packets entering the Virtual
Connect domain before they are routed to the appropriate server).
Following is an example of an uplink port being defined as a shared uplink port so that it can then be
used as the external connection for multiple networks.
