## Logical Interconnect

Screen component | Description
--- | ---
Graphical configuration of the logical interconnect | 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: Add, edit, or remove an uplink set which includes adding or removing networks and uplink ports Add or remove internal networks 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.

## General

Screen component | Description
--- | ---
Consistency state | Validation of the logical interconnect:
`Consistent` | The configuration of the logical interconnect matches the configuration set by the logical interconnect group.
`Inconsistent with group` | The configuration of the logical interconnect does not match the configuration set by the logical interconnect group. See Update the logical interconnect configuration from the logical interconnect group.
Stacking health | The stacking health status based on whether there are redundant paths for the logical interconnect:
`Redundantly Connected` | At least two independent paths between any pair of interconnects in the logical interconnect, and at least two independent paths from any downlink port on any interconnect in the logical interconnect to any other port (uplink or downlink) in the logical interconnect.
`Connected` | A single path between any pair of interconnects in the logical interconnect, and a single path from any downlink port on any interconnect in the logical interconnect to any other port (uplink or downlink) in the logical interconnect.
`Disconnected` | At least one interconnect is not connected to the other member interconnects in the logical interconnect.
`None` | No interconnects or the interconnects do not support stacking.
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.
Logical Enclosure | The name of the logical enclosure with which the logical interconnect is associated is a hyperlink to the Logical Enclosures screen.
Interconnects | The number of physical interconnects associated with the logical interconnect is a hyperlink to the Interconnects screen.
Logical Interconnect Group | The name of the parent logical interconnect group of the logical interconnect is a hyperlink to the Logical Interconnect Groups screen.
Ethernet networks | The number of Ethernet networks configured as part of the logical interconnect, is a hyperlink to the Networks screen.
`redundant paths` | Network assigned to an uplink set with two (or more) linked uplink ports.
`single path` | Network assigned to an uplink set with a single linked uplink port.
Fibre Channel networks | The Fibre Channel network configured as part of the logical interconnect, is a hyperlink to the Networks screen.
`assigned` | Network assigned to an uplink set. The network can communicate with the storage attached to the interconnect.
FCoE networks | The FCoE networks configured as part of the logical interconnect, is a hyperlink to the Networks screen.
`assigned` | Network assigned to an uplink set. The network can communicate with the storage attached to the interconnect.

## Firmware

Screen component | Description
--- | ---
Firmware baseline | Firmware version set as the baseline for the logical interconnect or `Not set` if a baseline was not selected.
Interconnect | Name of the physical interconnect, which is a link to the Interconnects screen for more information.
Model | Model of the interconnect.
Installed | Firmware version currently installed on the physical interconnect.
Baseline | 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`.

## Internal Networks

Screen component | Description
--- | ---
Internal Networks | 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. For more information, see About internal networks

## Stacking Links

Screen component | Description
--- | ---
Stacking Links | 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.

## Interconnect settings

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

The following interconnect settings apply to Ethernet interconnects and do not apply to Fibre Channel interconnects.

Screen component | Description
--- | ---
Fast MAC cache failover | 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.
Default value: | `Enabled`
MAC refresh interval | Time interval at which MAC caches are refreshed.
Data type: | Numeric; unit of measure is seconds.
Default value: | 5
IGMP snooping | 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.
Default value: | `Disabled`
IGMP idle timeout interval | 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.
Data type: | Numeric; unit of measure is seconds.
Default value: | 260
Required: | Yes, if IGMP snooping is enabled.
Loop protection | Loop protection, when enabled, detects loops on downlink ports and disables the port. For more information, see About loop protection.
Default value: | `Enabled`
Pause flood 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.
Default value: | `Enabled`
LLDP tagging | 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.
Enable | HPE OneView obtains the IPv4 and IPv6 addresses of the Virtual Connect interconnect in the lowest number bay location in the logical interconnect and advertises these addresses as the management address TLV for all the Virtual Connect interconnects in the logical interconnect.
Disable | By default, each Virtual Connect interconnect advertises its master interconnect's IPv4 and IPv6 address in the LLDP management address TLV.
Default value: | `Disabled`
LLDP enhanced TLV | 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
Default value: | `Disabled`

## Utilization Sampling

The Utilization Sampling settings control the data collection rate for all port statistics on the Interconnects screen. The port statistics display as graphs when you hover your pointer over the Utilization screen component.

You can enable or disable utilization sampling. You can change the sampling settings to specify the time period for which you want to generate graphs. The utilization data that is collected is based on the sample count and the sample interval value. The default values provide an hours’ worth of data. You can increase or decrease the frequency of the sample interval, and increase or decrease the number of samples to be stored. The adjustment of either value controls the length of the overall time for which data is available.

In addition to specifying time between samples of utilization data, the interval between samples specifies the frequency at which data is refreshed on the Interconnects screen.

Screen component | Description
--- | ---
Sample collection | Specifies whether utilization sampling is enabled or disabled
Interval between samples | Specifies the time, in seconds, between samples of utilization data.
Data type: | A value greater than or equal to 60.
Default: | 300 seconds.
Total number of samples | Specifies the total number of samples to be collected
Data type: | A value greater than or equal to 12.
Default: | 12
Sample collection rate | Number of samples to be collected per hour.
Total sampling history | Total sampling time, based on the specified number of samples and the interval between samples.

## SNMP

## Quality of Service (QoS)

Screen component | Description
--- | ---
QoS configuration type | 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:
`Passthrough` | All ingress packets are not classified at egress. FCoE packets having a separate PG (Priority Group) are processed at ingress. There are no traffic classes, maps, or rules applied. `Passthrough` mode is equivalent to no QoS (QoS disabled).
`Custom (with FCoE lossless)` | Enables QoS and allows a customized configuration that includes FCoE class. The configuration defines two default system classes, `Best Effort` and `FCoE Lossless`. FCoE Lossless class cannot be edited by the user and is pre-configured for 50% bandwidth of the port. You can also configure up to six additional classes for non-FCoE Ethernet traffic.
`Custom (without FCoE lossless)` | Enables QoS and allows a customized configuration without FCoE. The configuration defines one system class (`Best Effort`). You can configure up to seven additional classes for non-FCoE Ethernet traffic.
Classification for uplinks | 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.
`Dot1p` | A 3-bit field called the Priority Code Point (PCP) within an Ethernet frame header when using VLAN tagged frames as defined by IEEE 802.1Q. Eight different classes of service are available as expressed through the 3-bit PCP field.
`DSCP` | Differentiated Services Code Point (DSCP) is a field in an IP packet that enables different levels of service to be assigned to network traffic.
`DSCP and Dot1p` | For IP traffic use DSCP, and for non-IP traffic use dot1p priority.
Classification for downlinks | Downlink ports can be configured for ingress traffic classification based on the values of dot1p or DSCP or both.
`Dot1p` | A 3-bit field called the Priority Code Point (PCP) within an Ethernet frame header when using VLAN tagged frames as defined by IEEE 802.1Q. Eight different classes of service are available as expressed through the 3-bit PCP field.
`DSCP` | Differentiated Services Code Point (DSCP) is a field in an IP packet that enables different levels of service to be assigned to network traffic.
`DSCP and Dot1p` | For IP traffic use DSCP, and for non-IP traffic use dot1p priority.
Traffic Class | 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.
Enabled | Specifies whether to enable or disable the traffic class.
% Share | 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%.
Data type: | Value between 1 and 100
Max Share | 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.
Data type: | Value between 1 and 100
Real Time | 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.
Egress DOT1P Priority | 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.

## Add or edit SNMP Access

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

SNMP access enables you to configure addresses that are allowed to receive responses from interconnects when they query for SNMP information. You can define up to 16 SNMP access addresses.

If one or more IP or Subnet addresses are specified for SNMP access, only those addresses can receive responses from the interconnects. If no addresses are configured for SNMP access, any IP address can receive responses from the interconnects using SNMP.

Not available for Virtual Connect Fibre Channel interconnects.

Screen component | Description
--- | ---
IP or Subnet | Address of a host or manager that uses SNMP commands to access read values from an interconnect.
Data type: | SNMP access IP addresses are specified in CIDR (Classless Inter-Domain Routing) format.
Data type: | IPv4 and IPv6 addresses are supported.

## 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`

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 if the network accepts tagged and untagged packets from an upstream data center switch. Not applicable for FCoE.
To add networks, see Add 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.
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.

Update action | Specifies the firmware action for the logical interconnect. See About firmware associated with a logical interconnect for more information.
Firmware baseline | Specifies the firmware version set as the baseline for the logical interconnect.
Force installation | 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.
Ethernet activation | Specifies the firmware activation option for any Ethernet interconnects. See the About activating firmware options for more information.
Default value: | Odd/even
Activate firmware for | When activating firmware, specify which modules are to be activated. All interconnects are selected by default.
Delay | 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.
Default value: | 5
Fibre Channel activation | Specifies the firmware activation option for any Fibre Channel interconnects. See the About activating firmware options for more information.
Default value: | Serial
