If there is only one file, it can safely assume that this must be the IOS image to load. However, if the router has several images in its flash storage, you need to specify which one it should load, or the router will simply select one. This is particularly true on routers that have additional flash memory in the form of PCMCIA cards, which can hold many files, not all of which are even necessarily IOS images. With the default configuration register settings, the router will attempt to load the first accessible IOS image it finds in its flash storage.
However, loading the first available image might not be appropriate. For instance, in our last recipe we showed that, if you have space, you can download a new IOS image without erasing old images. In this case, you probably want the router to load the newer IOS image.
And it would be better still if the router would try the new image first, and revert to the old image if the first one failed to load correctly for any reason.
The boot system command allows you to specify not only which IOS images to boot from, but also the order to try them in if it has trouble booting. In the example, this router will try a succession of three different IOS images.
If they all fail, it will resort to using its boot ROM image. You must ensure that these ports are open for traffic flows to and from the appliance, whether you open them using firewall settings or a proxy gateway.
Additional ports, protocols, and types of traffic must be accommodated if you are deploying the appliance in a network that employs SDA infrastructure. Other common ports such as can also be used when a proxy is configured using the Configuration wizard if a proxy is already in use for your network. To access Cisco-supported certificates and trust pools, configure your network to allow outgoing IP traffic from the appliance to the Cisco addresses listed at:.
This topic details the ports, protocols, and types of traffic native to a typical Cisco SD-Access fabric deployment that is similar to the one shown in the following figure.
If you have implemented Cisco SD-Access in your network, use the information in the following tables to plan firewall and security policies that secure your Cisco SD-Access infrastructure properly while providing Cisco DNA Center with the access it requires to automate your network management. Source Port 2. From Cisco DNA Center to fabric switches for software upgrades also to the internet if there is no proxy. Source Port 3. Source Port 4. During appliance configuration, you will be prompted for the following information, in addition to the Required IP Addresses and Subnets :.
Linux User Name : This is maglev. This user name is the same on all the appliances in a cluster, including the primary node and add-on nodes, and cannot be changed. Linux Password : Identifies the password for the Linux user name maglev. This password ensures secure access to each appliance using the Linux command line. If required, you can assign a different Linux password for each maglev Linux user name on each appliance in a cluster. You must create the Linux password because there is no default.
The password must meet the following requirements:. If you are deploying a multinode cluster, you will also be prompted to enter the primary node's Linux password on each of the add-on nodes. The Maglev Configuration wizard generates a random and secure password using this seed phrase.
You can further edit the generated password by using the Auto Generated Password field. You are prompted to change this password when you log in for the first time. You must create this password because there is no default. The Administrator Passphrase must meet the same requirements as the Linux password, described earlier. It can be changed back to password only by a reset to factory defaults. After you have configured your appliances, log in to Cisco DNA Center and complete the essential setup tasks.
During this first-time setup, you should have the following information:. Resetting the super user password enhances operational security. This release supports InfoBlox and Bluecat. We recommend that you always use one of these new user accounts for all your normal Cisco DNA Center operations. Avoid using the admin super user account for activities, except reconfiguring Cisco DNA Center and operations where super user privileges are explicitly required.
For details about how to launch and respond to the first-time setup wizard that prompts you for this information, see Log In for the First Time. You will also need the following information to complete the remaining setup tasks, which can be done after your first login:. You can then start the data migration. Cisco DNA Center data present in the previous version is preserved when you upgrade. If the migration encounters a conflict, preference is given to data from Cisco ISE.
This allows you to make policy changes directly in Cisco ISE. This information is required to integrate Cisco DNA Center with your chosen authentication and policy server, as explained in Configure Authentication and Policy Servers.

Interface Cable Connections Connect the ports on the appliance to switches providing the following types of network access. Note The interface name assigned to ports on 44, 56, and core appliances differs. Figure 3. Recommended Cabling for Three-Node Cluster: Core Appliance For more details on each of the ports, see the rear panel diagram and accompanying descriptions for your chassis in Front and Rear Panels.
Note Multinode cluster deployments require all the member nodes to be in the same network and at the same site. Now open cdrtfe.
Under the Data Disc tab click Options. Check Create image only, do not burn. Click Ok. Next, click the File System button. We recommend that you create a template from a Cisco ISE VM that you have just installed and not run the setup program on. You can then run the setup program on each of the individual Cisco ISE nodes that you have created and configure IP address and hostnames individually.
Enter a name for the template, choose a location to save the template in the Name and Location dialog box, and click Next. Choose the ESXi host that you want to store the template on and click Next. Choose the datastore that you want to use to store the template and click Next. Ensure that this datastore has the required amount of disk space. After you create a virtual machine template, you can deploy it on other virtual machines VMs.
Click the Do not customize radio button in the Guest Customization dialog box. Check the Edit Virtual Hardware check box and click Continue. Ensure that the Cisco ISE node is in the standalone state. Uncheck the Connected and Connect at power on check boxes. Otherwise, if this node comes up, it will have the same IP address as the source machine from which it was cloned. Ensure that you have the IP address and hostname that you are going to configure for the newly cloned VM as soon as you power on the machine.
You cannot use "localhost" as the hostname for a node. The hostname is the new hostname that you are going to configure. The Cisco ISE services are restarted.
The system will prompt you to restart the Cisco ISE services. After you power on and change the ip address and hostname, you must connect the Cisco ISE node to the network. Click Network adapter in the Virtual Machine Properties dialog box. In the Device Status area, check the Connected and Connect at power on check boxes. Click OK. After evaluating the Cisco ISE release, you can migrate the from an evaluation system to a fully licensed production system.
When you move the VMware server to a production environment that supports a larger number of users, be sure to reconfigure the Cisco ISE installation to the recommended minimum disk size or higher up to the allowed maximum of 2. You can only migrate data from VMs created with GB or more disk space to a production environment. Back up the configuration of the evaluation version. Ensure that your production VM has the required amount of disk space. Restore the configuration to the production system.
You can run the show tech-support command from the CLI to check the VM performance at any point of time. The output of this command will be similar to the following:.
You can check for virtual machine resources independent of Cisco ISE installation from the boot menu. The following screen appears:. Enter 2 to check for VM resources. The output will be similar to the following:.
You must see either the vmx or the svm flag. From the virt-manager, click New. The Create a new virtual machine window appears. Uncheck the Automatically detect operating system based on install media check box, choose Linux as the OS type, choose supported Red Hat Enterprise Linux version, and click Forward.
