19.2.3.1 Uplink Sets

An uplink set defines a single, dedicated network or 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 tagged Ethernet networks, an uplink set enables you to identify interconnect uplinks that carry
multiple networks over the same cable. For untagged or tunnel Ethernet networks, an uplink set
identifies interconnect uplinks that are dedicated to a single network. For Fibre Channel connections,
you can 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 active/active configurations,
create a new logical interconnect group rather than updating an existing 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 one or more tagged Ethernet networks. An uplink set for an untagged
or a tunnel network can only contain that one untagged or tunnel network.

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
