Dcnm Release Download

To determine the Cisco Prime DCNM release that is running, administrators can connect to the computer that runs the Cisco Prime DCNM software using a web browser and HTTPS; the release number will be displayed in the login page, before logging in. The following example shows a device running version 7.0(2):

Cisco DCNM-LAN Server and Cisco DCNM-SAN Server were different products prior to the release of 6.1(1), when both products converged into a single Cisco Prime DCNM product. The original standalone versions of Cisco DCNM-LAN Server and Cisco DCNM-SAN Server and the converged versions prior to 6.3(1) are not affected by this vulnerability.

In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.

In March 2022, the Cisco Product Security Incident Response Team (PSIRT) became aware of additional attempted exploitation of this vulnerability in the wild. Cisco continues to strongly recommend that customers upgrade to a fixed software release to remediate this vulnerability.

Cisco Data Center Network Manager (DCNM) version 11.3(1) and earlier releases use the interface called Out-of-Band Network (eth1 in DCNM Linux shell) to communicate, push and sync configurations with the Switching fabric. To do this, DCNM first needs to discover the Switching Fabric by either manually specifying the pre-provisioned Switches' mgmt0 IP address or by auto-discovering these Switches using the POAP (Power On Auto Provisioning) process.

The network manager can now import directly to DCNM 11.1 an existing VXLAN EVPN Fabric while the DC network continues to provide connectivity to production endpoints. Typically, the original VXLAN fabric has been previously created and managed through manual CLI configurations or custom automation scripts. With this new software release, the Network manager can import an existing VXLAN network and start managing the fabric through DCNM. All configurations, as well as logical Networks and VRFs are preserved. The migration happens without interruption. After the migration, the initial configurations of the VXLAN Fabric underlay and overlay networks will be managed by DCNM and new devices, Networks and VRFs can be added afterward seamlessly.

The templates of templateType = CLI are converted to templateType = POLICY. These templates are displayed in Control > Template Library. If needed, PTIs can be created from the View/Edit Policies window. NoteIf policies that are updated automatically need to be reviewed, a backup of the original file is saved with a .bak extension in the following directory on DCNM: /usr/local/cisco/dcm/dcnm/data/templates/.Some of the template language constructs that are available in Classic LAN are not supported in LAN Fabric installation. For example:

This creates a session which allows you to execute the commands. The commands continue to run even when the window is not visible or if you get disconnected.Step 2 Take a backup of the application data using the appmgr backup command. dcnm# appmgr backup

Step 5 Create folder that is named iso using the mkdir /mnt/iso command.[root@dcnm]# mkdir /mnt/isoStep 6 Mount the DCNM 11.5(1) ISO file on the standalone setup in the /mnt/iso folder. mount -o loop /mnt/iso

The system reboots after upgrade.Step 9 Ensure that the DCNM application is functional, by using the appmgr status all command.

[root@dcnm]# appmgr status allStep 10 To verify that you have successfully installed the Cisco DCNM Release 11.5(1), use the appmgr show version command.

Step 11 Terminate the screen session, by using the exit command.[root@dcnm]# exitStep 12 Unmount the dcnm-va-patch.11.5.1.iso file from the DCNM setup.Note You must terminate the screen session before unmounting the .iso file.[root@dcnm]# umount /mnt/isoWhat to do next

Run the following command to create a screen session.dcnm1# screendcnm2# screenThis creates a session which allows you to execute the commands. The commands continue to run even when the window is not visible or if you get disconnected.Step 3 Take a backup of the application data using the appmgr backup command on both Active and Standby appliances.

Copy the backup file to a safe location outside the DCNM server.Step 4 Log on to the /root/ directory by using the su command.dcnm1# suEnter password: [root@dcnm1]#dcnm2# suEnter password: [root@dcnm2]#Note Ensure that you have access to the /root/ folder before you mount the ISO to the directory.

a) Create a folder named iso using the mkdir /mnt/iso command.[root@dcnm1]# mkdir /mnt/isob) Mount the DCNM 11.5(1) ISO file on the Active node in the /mnt/iso folder.

c) Navigate to /mnt/iso/packaged-files/scripts/ location and run the ./inline-upgrade.sh script.[root@dcnm1]# cd /mnt/iso/packaged-files/scripts/dcnm1# ./inline-upgrade.shNote

If some services are still running, you will receive a prompt that the services will be stopped. When prompted, press y to continue.[root@dcnm1]# Do you want to continue and perform the inline upgrade to 11.5(1)? [y/n]: yd) Provide the new sysadmin user password at the prompt:

The system reboots after upgrade.e) Ensure the DCNM application is functional, by using the appmgr status all command.[root@dcnm1]# appmgr status allNote

Ensure that all the services are up and running on the Cisco DCNM Active node before proceeding to upgrade Standby node.

f) Verify the role of the Active node, by using appmgr show ha-role command. Current role must show as Active.[root@dcnm1]# appmgr show ha-roleNative HA enabled.Deployed role: ActiveCurrent role: ActiveWarning

We recommend that you do not continue to upgrade the Standby node, unless the Active node Current role is Active.Step 6 On the Standby node, perform the inline upgrade.

a) Create folder named iso using the mkdir /mnt/iso command.[root@dcnm2]# mkdir /mnt/isob) Mount the DCNM 11.5(1) ISO file on the Standby node in the /mnt/iso folder.[root@dcnm2]# mount -o loop dcnm-va.11.5.1.iso /mnt/isoc) Navigate to /mnt/iso/packaged-files/scripts/ location and run the ./inline-upgrade.sh script.

After the upgrade is complete, the appliance reboots. After reboot, the SSH \root access is disabled by default. Use sysadmin user.After the upgrade is complete, the appliance reboots. Verify the role of the appliance, using the following command:[root@dcnm2]# appmgr show ha-roleNative HA enabled.Deployed role: StandbyCurrent role: StandbyStep 7 Terminate the screen session, by using the exit command.

Step 8 Unmount the dcnm-va-patch.11.5.1.iso file in both Active and Standby node of the DCNM setup.Note You must terminate the screen session before unmounting the .iso file.[root@dcnm1]# umount /mnt/iso[root@dcnm2]# umount /mnt/isoWhat to do next

Step 2 Unzip the dcnm-va.11.5.1.iso.zip file and upload the DCNM 11.5(1) ISO file to the /root/ folder in all the compute nodes.Step 3 Create folder that is named iso using the mkdir /mnt/iso command, on all the computes.

Mount the ISO on all the compute nodes.Step 5 Navigate to /mnt/iso/packaged-files/scripts and run the ./inline-upgrade.sh script.dcnm-compute# cd /mnt/iso/packaged-files/scriptsdcnm-compute# ./inline-upgrade.sh --task-disable updatePoapUserdcnm-compute# ./inline-upgrade.shDo you want to continue and perform the inline upgrade to 11.5(1)? [y/n]: yNote

If some services are still running, a prompt to stop the services appears. When prompted, press y to continue

Step 7 Verify that you have successfully upgraded to Cisco DCNM Release 11.5(1), using the appmgr show version command.dcnm-compute# appmgr show versionCisco Data Center Network ManagerVersion: 11.5(1)Install mode: ComputeStep 8 Terminate the screen session, by using the exit command on all compute nodes.dcnm-compute# exitStep 9 Unmount the dcnm-va-patch.11.5.1.iso file from all compute nodes of the DCNM setup.

Note You must terminate the screen session on all compute nodes before unmounting the .iso file.dcnm-compute# umount /mnt/isoWhat to do next You must upgrade all the three compute nodes in the cluster. 17dc91bb1f
