Because appropriate VLAN tags are added as the packets leave the enclosure, this type of uplink should
not be used in cases where VLAN tags are already added on the server itself. The system drops any
Ethernet packets with server-inserted VLAN tags that are received on networks connected to shared uplink
ports.
Mapping multiple networks to a shared uplink port set
It is also possible to map multiple VLAN-tagged networks to a set of shared uplink ports. The resulting
shared uplink port set allows for the minimum number of cables while still providing for link aggregation
and failover.
In the following example, a shared uplink port set is first defined to provide aggregation and failover.
Shared_Uplink_Set_A = {Enclosure1:Bay1:PortX2, Enclosure1:Bay2:PortX2}

In this example, all of the defined networks share a single active uplink port (such as
Enclosure1:Bay1:PortX2) using VLAN tagging, while the second link in the shared uplink port set is
available for failover. The shared uplink port set can also be constructed of multiple 1-Gb external ports.
IMPORTANT: One network can be designated as a native VLAN, causing all untagged
incoming Ethernet packets to be placed on this network. See the additional information on
shared uplink sets and VLAN tagging in the HP Virtual Connect for c-Class BladeSystem User
Guide.
To make Virtual Connect Manager aware of shared network connections, see the information on defining
new shared uplink sets in the HP Virtual Connect for c-Class BladeSystem User Guide.
Configuration example using a Cisco Core switch
There are several ways to implement a redundant Virtual Connect configuration. This example provides a
reference for anyone unfamiliar with switch configurations. This example is just one of several ways to
connect an HP Virtual Connect to a Cisco Core switch.
