Uplink sets
An uplink set defines a group of networks and physical ports on the interconnect in an enclosure.
An uplink set enables you to attach the interconnect to the data center networks. An uplink set
enables multiple ports to support port aggregation (multiple ports connected to a single external
interconnect) and link failover with a consistent set of VLAN networks.
For Ethernet connections, an uplink set enables you to identify interconnect uplinks that carry multiple
networks over the same cable. For Fibre Channel connections, you can only add one network to
an uplink set. Fibre Channel does allow virtual networks or VLANs.
An uplink set is part of a logical interconnect. The initial configuration of the uplink sets for a logical
interconnect is determined by the configuration of the uplink sets for the logical interconnect group,
but you can change (override) the uplink sets for a specific logical interconnect. Changes you make
to the uplink sets for a logical interconnect group are not automatically propagated to existing
logical interconnects. For example, to propagate a newly added VLAN to a logical interconnect
group uplink set to its existing logical interconnects, you must individually update each logical
interconnect configuration from the logical interconnect group.
For each logical interconnect:
• You can define zero, one, or multiple uplink sets. If you do not define any uplink sets, the
servers in the enclosure cannot connect to data center networks.
• A network can be a member of one uplink set only.
• An uplink set can contain only one Fibre Channel network.
• An uplink set can contain multiple Ethernet networks.
• You must specify Ethernet networks individually. The use of network sets in uplink sets is not
supported for the following reasons:
◦ The networking configuration is intended to be managed by users with a role of Network
administrator. Because users with a role of Server administrator can create and edit
network sets, allowing network sets to be members of uplink sets could result in server
administrators changing the mapping of networks to uplink ports without the knowledge
of the network administrator.
◦ Because a network can be a member of more than one network set, allowing network
sets to be members of uplink sets would make it more difficult to ensure that no single
network is a member of more than one uplink set, especially as the network set
configurations change over time.
