The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco APIC-EM supports a web interface using the following HTTPS-enabled browsers:
If you enter an incorrect password for your specified administrator user ID eight times, the Cisco APIC-EM user interface “locks you out” of the system.
See the Cisco Application Policy Infrastructure Controller Enterprise Module Troubleshooting Guide for information about recovering from an administrator lockout.
After you have installed Cisco APIC-EM, you can log into its web-based interface. You must use only supported HTTPS-enabled browsers.
To log out of the Cisco APIC-EM web-based interface, click Log Out on the Cisco APIC-EM main window toolbar. This ends your administrative session and logs you out.
Note | For security reasons, we recommend that you log out when you complete your administrative session. If you do not log out, the Cisco APIC-EM GUI interface logs you out after 30 minutes of inactivity. |
See the Cisco Application Policy Infrastructure Controller Enterprise Module Administrator's Guide for information about installing certificates on the controller.
If you need to reconfigure your Cisco APIC-EM configuration, you must use the configuration wizard to do so. You cannot use the Linux CLI. Perform the steps in this procedure to change the Cisco APIC-EM configuration wizard settings, including the external network settings, NTP server address, and/or password for the Linux grapevine user. The external network settings that could be changed include:
Note | In order to change the external network settings, NTP server address, and/or the Linux grapevine user password in a multi-host deployment, you need to first break up the multi-host cluster. Therefore, when performing this procedure controller downtime occurs. For this reason, we recommend that you perform this procedure during a maintenance time period. |
Step 1 | Using a Secure
Shell (SSH) client, log into one of the hosts in your cluster.
Log in using the IP address that you specified using the configuration wizard.
| ||
Step 2 | When prompted, enter your Linux username ('grapevine') and password for SSH access. | ||
Step 3 | Enter the
following command to access the configuration wizard.
$ config_wizard | ||
Step 4 | Review the Welcome to the APIC-EM Configuration Wizard! screen and choose the option to remove the host from the cluster: | ||
Step 5 | A message
appears with the following options:
At the end of this process, this host is removed from the cluster. | ||
Step 6 | Repeat the above
steps (steps 1-5) on a second host in the cluster.
| ||
Step 7 | Using a Secure
Shell (SSH) client, log into that final host in your cluster and run the
configuration wizard.
$ config_wizard After logging into the host, begin the configuration process. | ||
Step 8 | Make any
necessary changes to the configuration values for the external network
settings, NTP server address, and/or password for the Linux grapevine user
using the wizard.
After making your configuration change(s), continue through the configuration process to the final message. | ||
Step 9 | At the end of
the configuration process, a final message appears stating that the wizard is
now ready to proceed with applying the configuration.
The following options are available:
Enter proceed>> to complete the installation. After entering proceed>>, the configuration wizard applies the configuration values that you entered above.
At the end of the configuration process, a CONFIGURATION SUCCEEDED! message appears. | ||
Step 10 | Log into the
other hosts in your multi-host cluster and use the configuration wizard to
recreate the cluster.
