About uplink sets

An uplink set defines a single, dedicated network or a group of networks and physical ports on a set of interconnects in an enclosure. An uplink set enables you to attach the interconnects 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.

Uplink set configuration

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 Groups, 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 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 networks, you can add one network to an uplink set. Fibre Channel does not allow virtual networks or VLANs.

  • For Fibre Channel over Ethernet (FCoE) networks, an uplink set enables you to carry multiple Fibre Channel and tagged Ethernet networks over the same set of Ethernet cables.

  • One uplink set per Cisco FEX module is allowed.

For each logical interconnect:

  • You can define zero or more uplink sets. See networking limits in the HPE OneView Support Matrix.

    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 per logical interconnect group only.

  • An uplink set with Fibre Channel or FCoE networks can use uplinks from only one interconnect.

  • 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.

  • An uplink set can contain one or more FCoE networks, but the uplinks must be contained within a single FCoE-capable interconnect. See firmware requirements in About Fibre Channel over Ethernet (FCoE) networks.

  • Within a logical interconnect group or logical interconnect, all VLAN IDs must be unique across uplink sets and internal networks.

  • Internal networks allow server-to-server connectivity within the logical interconnect. Internal networks are created by adding existing networks to the internal networks set. Internal networks can be added to uplink sets which automatically remove them from the internal networks set. Cisco FEX modules do not support internal networks.

  • When you create an uplink set, you can directly add network sets.

  • When you modify an uplink set, you can directly add or remove network sets.

While creating an uplink set, you can perform the following activities:
  • Associate zero or more network sets with the uplink set. Also, you can associate a zero or more network sets with an existing uplink set.
  • You can remove a network set from an uplink set.
