Log In to Cisco Intersight

Log In using Cisco ID

To login to Cisco Intersight, you must have a valid Cisco ID to create a Cisco Intersight account. If you do not have a Cisco ID, create one here.


Important

The device connector does not mandate the format of the login credentials, they are passed as is to the configured HTTP proxy server. Whether or not the username must be qualified with a domain name will depend on the configuration of the HTTP proxy server.

Log In using Single Sign-On

Single Sign-On (SSO) authentication enables you to use a single set of credentials to log in to multiple applications. With SSO authentication, you can log in to Intersight with your corporate credentials instead of your Cisco ID. Intersight supports SSO through SAML 2.0, and acts as a service provider (SP), and enables integration with Identity Providers (IdPs) for SSO authentication. You can configure your account to sign in to Intersight with your Cisco ID and SSO. Learn more about SSO with Intersight here.

Cluster Network

Uplink Speed drop-down list

Select the link speed of the server adapter port to the upstream switch. The Uplink speed can be:

  • 1G (HyperFlex Edge)

  • 10G+ (HyperFlex Edge)

When the policy is attached to a cluster profile with Edge management platform, the uplink speed can be '1G' or '10G+'. When the policy is attached to a cluster profile with Fabric Interconnect management platform, the uplink speed can be 'default' only.

Refer to the Preinstallation Checklist for Cisco HyperFlex Edge for more details of the supported Network Topologies.

Attention 

Using 10G+ mode typically requires the use of forward error correction (FEC) depending on the transceiver or the type & length of cabling selected. The VIC 1400 series by default is configured in CL91 FEC mode (FEC mode “auto” if available in the Cisco IMC UI is the same as CL91) and does not support auto FEC negotiation. Certain switches will need to be manually set to match this FEC mode to bring the link state up. The FEC mode must match on both the switch and VIC port for the link to come up. If the switch in use does not support CL91, you may configure the VIC ports to use CL74 to match the FEC mode available on the switch. This will require a manual FEC mode change in the CIMC UI under the VIC configuration tab. Do not start a HyperFlex Edge deployment until the link state is up as reported by the switch and the VIC ports. CL74 is also known as FC-FEC (Firecode) and CL91 is also known as RS-FEC (Reed Solomon). See the Cisco UCS C-Series Integrated Management Controller GUI Configuration Guide for further details on how to change the FEC mode configured on the VIC using the Cisco IMC GUI.

Management Network VLAN ID field

Enter the VLAN ID for the management network. VLAN must have access to Intersight.

An ID of 0 means the traffic is untagged. The VLAN ID can be any number between 0 and 4095, inclusive.

Jumbo Frames check box

Check this check box to enable Jumbo Frames.

Jumbo Frames are optional and can remain disabled for HyperFlex Edge deployments.

Proxy Setting (Optional Policy)

Hostname field

Enter the HTTP proxy server FQDN or IP address.

Port field

Enter the proxy port number.

Username field

Enter the HTTP Proxy username.

Password field

Enter the HTTP Proxy password.

HyperFlex Storage Network

Storage Network VLAN ID field

Enter the VLAN ID for the storage VLAN traffic. The VLAN must be unique per HyperFlex cluster.

Note 

The storage VLAN must be unique per HyperFlex cluster. This VLAN does not need to be routable and can remain layer 2 only. IP addresses from the link local range 169.254.0.0/16 are automatically assigned to storage interfaces. A storage VLAN is not required for two node HyperFlex Edge 1GE configurations, and you should enter 1 for this field.

Click Next.

Step 8

In the Nodes Configuration page, you can view the IP and Hostname settings that were automatically assigned. Intersight will make an attempt to auto-allocate IP addresses. Complete the following fields:

Field

Description

Cluster Management IP Address field

The cluster management IP should belong to the same subnet as the Management IPs.

MAC Prefix Address field

The MAC Prefix Address is auto-allocated. For 10G+ HyperFlex Edge clusters you can overwrite the MAC Prefix address, using a MAC Prefix address from the range 00:25:B5:00 to 00:25:B5:EF.

Attention 

Ensure that the MAC prefix is unique across all clusters for successful HyperFlex cluster deployment. Intersight does a validation for duplicate MAC prefix and shows appropriate warning if any duplicate MAC prefix is found.

Replication Factor radio button

The number of copies of each data block written. The options are 2 or 3 redundant replicas of your data across the storage cluster.

Important 

Replication factor 3 is the recommended option.

Hostname Prefix field

The specified Hostname Prefix will be applied to all nodes.
Step 9

In the Summary page, you can view the cluster configuration and node configuration details. Review and confirm that all information entered is correct. Ensure that there are no errors triggered under the Errors/Warnings tab.

Note 

When deploying 2 Node Edge clusters a warning will be displayed reminding of the importance of connectivity to Intersight. Ensure that your cluster rem4.ains connected to Intersight at all times. A second warning will be shown reminding users to implement a backup strategy to ensure that all user data is protected.

Step 10

Click Validate and Deploy to begin the deployment. Optionally, click Validate, and click Save & Close to complete deployment later. The Results page displays the progress of the various configuration tasks. You can also view the progress of the HyperFlex Cluster Profile deployment from the Requests page.
