Logical Interconnects screen details

The display of the logical interconnect relationships is the same as shown on the Logical Interconnect Groups screen.

From this view, you can perform the following actions:

Each interconnect name is a link to the Interconnects screen for more information. Additionally, this view displays the interconnect state, and the expected and actual model of interconnect.

Numbered tabs from the interconnects indicate the bay slot where the interconnect is located within the enclosure.

Validation of the logical interconnect:

The stacking health status based on whether there are redundant paths for the logical interconnect:

Stacking health status is based on the redundancy status of the logical interconnect. HPE OneView determines whether or not logical interconnects have a single path or dual paths between two interconnects.

The configuration defined in the logical interconnect group is the expected configuration within the enclosure. If any of the interconnects are defined to be in the Configured state but instead are in a different state, such as Absent, Inventory, or Unmanaged, the stacking health is displayed as Disconnected. If none of the interconnects are in the Configured state, no stacking health information is displayed.

The name of the logical enclosure with which the logical interconnect is associated is a hyperlink to the Logical Enclosures screen.

The number of physical interconnects associated with the logical interconnect is a hyperlink to the Interconnects screen.

The name of the parent logical interconnect group of the logical interconnect is a hyperlink to the Logical Interconnect Groups screen.

Firmware version set as the baseline for the logical interconnect or Not set if a baseline was not selected.

Name of the physical interconnect, which is a link to the Interconnects screen for more information.

Model of the interconnect.

Firmware version currently installed on the physical interconnect.

The intended firmware version from the firmware baseline, if set. This value is for comparison against the installed value or the value is Not set.

If manage manually is selected when adding an enclosure, the baseline for the interconnects are Not set. If subsequent firmware updates apply to the enclosure only, the baseline is Not set.

List of assigned internal Ethernet networks that allow server to server communication within the same logical enclosure without a top of rack switch. The VLAN ID is also shown for tagged networks.

Internal networks enable you to explicitly designate which logical interconnect and network to use for server-to-sever communication. For example, to have all servers communicating over network net_100, you can designate net_100 as an internal network for a logical interconnect. The server profile ensures that every server connected to net_100 uses the downlinks connected to the interconnect with net_100 on it.

If there are more than 50 networks, a link is displayed to the Networks screen, filtered to the list of networks that are in the set. Internal networks can contain tunnel and untagged networks, so instead of a VLAN ID, it will display tunnel or untagged as a label.

Duplicate VLAN IDs are allowed on internal networks because the external VLAN ID is not used to route traffic within the Virtual Connect stacking domain.

Ethernet networks are automatically moved from uplink sets to internal networks when removed from an uplink set on the logical interconnect to avoid an outage. However, if you remove an Ethernet network from an uplink set in a logical interconnect group, the network does not get moved automatically to the internal networks.

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

Specifies the stacking link configuration for a set of physical interconnects in an enclosure. By stacking (cabling together) Ethernet or FlexFabric modules in the logical interconnect, you can configure every server in the enclosure to access any external Ethernet network connection.

When an uplink that was in standby mode becomes active, it can take several minutes for external Ethernet interconnects to recognize that the server blades can now be reached on this newly active connection.

Enabling Fast MAC Cache Failover causes Ethernet packets to be transmitted on the newly active connection, which enables the external Ethernet interconnects to identify the new connection (and update their MAC caches).

The transmission sequence is repeated a few times at the MAC refresh interval and completes in about 1 minute.

Time interval at which MAC caches are refreshed.

IGMP (Internet Group Management Protocol) snooping feature allows interconnects to analyze the IGMP IP multicast membership activities and configure hardware Layer 2 switching behavior of multicast traffic to optimize network resource usage. Currently, only IGMP v1 and v2 (RFC 2236) are supported.

Group Membership Interval value, as specified by the IGMP v2 specification (RFC 2236).

For optimum network resource usage, set the timeout interval to match your network's multicast router settings.

Loop protection, when enabled, detects loops on downlink ports and disables the port. For more information, see About loop protection.

Pause flood protection, when enabled, detects pause flood conditions on server downlink ports and disables the port. For more information, see About pause flood protection.

LLDP tagging, when enabled, uses the management IP address of the lowest numbered Ethernet bay location in the logical interconnect. This IP address is transmitted in tagged LLDP frames on the downlink ports and untagged frames on the uplinks and stacking link ports. For more information, see About Link Layer Discovery Protocol (LLDP) tagging and Enable or disable Link Layer Discovery Protocol (LLDP) tagging.

LLDP enhanced TLV, when enabled, transmits enclosure name and serial number in the Chassis ID TLV of LLDP frames. For more information, see About enhanced type-length-value (TLV) structure

Three configuration types provide administrators with basic settings that can be further tuned depending on whether or not FCoE traffic is present in the HPE OneView environment:

Uplink ports can be configured for ingress traffic classification based on the values of dot1p or DSCP or both in Ethernet and IP headers respectively.

Downlink ports can be configured for ingress traffic classification based on the values of dot1p or DSCP or both.

A traffic class is a queue for classified packets at the port egress.

If you select QoS configuration type Custom with FCoE Lossless, the configuration has two default system classes - Best Effort and FCoE Lossless. You can configure up to six additional classes for non-FCoE Ethernet traffic.

If you select QoS configuration type Custom without FCoE Lossless, the configuration defines one system class (Best Effort), and you can configure up to seven additional classes for non-FCoE Ethernet traffic.

Specifies whether to enable or disable the traffic class.

Minimum guaranteed bandwidth for the traffic class.

The % share and the max share for a real time class must be equal and not exceed 50%.

Maximum share the traffic class can use when other traffic classes are not using their guaranteed share.

The max share and the % share for a real time class must be equal and not exceed 50%. For other classes, the max share is greater than or equal to the % share.

Specifies whether the traffic class is real time. Only 1 traffic class can be real time. Enabling real time for this class removes the real time flag for other classes.

Specifies the dot1p priority value to remark for the egressing packets. This provides flexibility to control priority treatment for packets at the next hops based on the remarked dot1p value.

A unique name for the traffic class.

Specifies whether to enable or disable the traffic class.

To add networks, see Add networks

For more information, see Data center switch port requirements.

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.
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

To add an uplink port, see Add uplink ports.

Specifies the firmware action for the logical interconnect. See About firmware associated with a logical interconnect for more information.

Specifies the firmware version set as the baseline for the logical interconnect.

Requires (forces) firmware update on every member interconnect regardless of its current installed version.

To install an older firmware version than the version contained in the SPP, you must select the Force installation option to downgrade the firmware. You might want to install older firmware if the newer firmware is known to cause a problem in your environment.

	CAUTION: Forcing a firmware downgrade might leave a server unstable.

Specifies the firmware activation option for any Ethernet interconnects. See the About activating firmware options for more information.

When activating firmware, specify which modules are to be activated. All interconnects are selected by default.

The amount of time, specified in minutes between 0–60, to wait between activating or rebooting VC Ethernet, FlexFabric, or VC-FC interconnect modules. Activation delay applies only to odd/even and serial activations and is optional. HPE recommends a minimum of 5 minutes.

	IMPORTANT: Setting the delay to a high value between activations results in long wait times in serial activation mode. For example, setting the delay to 60 minutes between activations will take one hour for each interconnect in the logical interconnect.

Specifies the firmware activation option for any Fibre Channel interconnects. See the About activating firmware options for more information.
