Create or edit uplink sets

This section applies to the Logical Interconnects and Logical Interconnect Group resources.

Screen component

Description

General
Name

Unique name for the uplink set you are creating. If available, follow your best practices for network component naming. For active/active configurations, follow the naming convention described in Requirements for an active/active configuration.

Type

(Add only)

Connection type of the uplink set.

Ethernet

An Ethernet uplink set contains multiple networks on a single uplink set, which allows you to share uplinks with those networks. Ethernet is also used for FCoE networks.

Fibre Channel

A Fibre Channel uplink set contains a single network used for storage.

Tunnel

A tunnel uplink set contains a single Ethernet tunnel network with a dedicated set of uplink ports used to pass a group of VLANs without changing the VLAN tags.

Untagged

An untagged uplink set contains a single untagged Ethernet network with a dedicated set of uplink ports used to pass untagged traffic (without VLAN tags).

Connection mode

(Ethernet type only)

Connection mode for the uplink set.

Automatic

Enables the uplinks to form aggregation groups using the IEEE 802.3ad LACP, and to select the highest performing uplink as the active path to external networks. Select Automatic in an active/active configuration.

Failover

Select Preferred if you want a single link to be the active link to the external networks. The other ports are standby connections. If the preferred uplink loses connectivity, a new active uplink set from the available standby uplinks is selected as the active network path. Selecting a new active uplink typically takes less than 5 seconds. If the previous preferred uplink is restored, connectivity fails back to it automatically.

LACP timer

(Ethernet type with automatic connection mode only)

Frequency of exchange of LACP control messages between devices in a LAG.

Short (1s)

Every 1 second with a 3-second timeout.

Long (30s)

Every 30 seconds with a 90-second timeout.

Default value:

Short

Networks
The list of networks for this uplink set, if any. The following information displays for Ethernet or FCoE networks.
Name

Name of the network.

Type

Type of network:

Ethernet

or

FCoE
VLAN ID

The VLAN ID for the Ethernet or FCoE network

Native

Indicates that the network accepts tagged and untagged packets from an upstream data center switch. Not applicable for FCoE.

To add networks, see Add or remove networks

For more information, see Data center switch port requirements.

Uplink Ports

The list of uplink ports for this uplink set, if any.

Interconnect Module

Name of the module.

Bay

Number of the bay where the physical port is located.

Port

Identifies the physical port of the interconnect module assigned to the uplink set. For more information on the Virtual Connect FlexFabric 20/40 F8 interconnect module, see About the Virtual Connect FlexFabric–20/40 F8 interconnect module.

You can designate an uplink port as Preferred, which applies when you create an uplink set and the connection mode is set to Failover. In failover mode, the preferred port is the port you want to be active and carry the traffic in the uplink set. All other ports in the uplink set are in standby mode. If the preferred port fails for any reason, a standby port takes over. If the connection mode is set to Automatic, the Virtual Connect interconnect decides which port is active or standby.

When adding uplink ports, a menu of available uplink ports is displayed.

NOTE:

Uplink ports are not available for third-party devices (such as Cisco Fabric Extender for HPE BladeSystem modules) that are not managed by the appliance.

Capability
Indicates whether the port is capable of handling FCoE traffic.
Ethernet

Ethernet-capable only

Ethernet + FCoE

Ethernet- and FCoE-capable

Preferred

Select Preferred if you want a single link to be the active link to the external networks. The other ports are standby connections. If the preferred uplink loses connectivity, a new active uplink from the available standby uplinks is selected as the active network path. Selecting a new active uplink typically takes less than 5 seconds. If the previous preferred uplink is restored, connectivity fails back to it automatically.

Preferred can be check marked if connection mode is Failover.

Speed

(Fibre Channel networks only)

Configured port speed for Fibre Channel uplink ports. The available discrete values are based on the adapter and the Fibre Channel interconnect module.

Default value:

Auto

Examples:
  • 2 Gb/s
  • 4 Gb/s
  • 8 Gb/s
