Logs cannot be viewed from a remote server in a federation. |
To view the logs from the Cisco DCNM Web UI, perform the following steps:
Procedure
Step 1 |
Choose Administration > DCNM Server > Logs. You see a tree-based list of logs in the left column. Under the tree, there is a node for every server in the federation. The log files are under the corresponding server node. |
Step 2 |
Click a log file under each node of the tree to view it on the right. |
Step 3 |
Double-click the tree node for each server to download a ZIP file containing log files from that server. |
Step 4 |
Click the Print icon on the upper right corner to print the logs. |
Server Properties
You can set the parameters that are populated as default values in the DCNM server.
To set the parameters of the DCNM server from the Cisco DCNM Web UI, perform the following steps:

SFTP Directory Path
Use Case 1:
If Cisco DCNM is installed on Linux platforms, like OVA, ISO, or Linux, and the test folder is located at /test/sftp/, you must provide the entire path of the SFTP directory. In the SFTP Directory field, enter /test/sftp.
Use Case 2:
If Cisco DCNM is installed on the Windows platform, and the test folder is located at C://Users/test/sftp/, you must provide the relative path of the SFTP directory. In the SFTP Directory field, enter /.
For Example:
-
If the path in the external SFTP is C://Users/test/sftp/, then the Cisco DCNM SFTP Directory path must be /.
-
If the path in the external SFTP is C://Users/test, then the Cisco DCNM SFTP Directory path must be /sftp/.
Examples for SCP Directory Path
Use Case 1:
If Cisco DCNM is installed on Linux platforms, like OVA, ISO, or Linux, and the test folder is located at /test/scp/, you must provide the entire path of the SCP directory. In the SCP Directory field, enter /test/scp.
Use Case 2:
If Cisco DCNM is installed on the Windows platform, and the test folder is located at C://Users/test/scp/, you must provide the relative path of the SCP directory. In the SCP Directory field, enter /.
For Example:
-
If the path in the external SCP is C://Users/test/scp/, then the Cisco DCNM SCP directory path must be /.
-
If the path in the external SCP is C://Users/test, then the Cisco DCNM SCP directory path must be /scp/.
Modular Device Support
To support any new hardware that does not require many major changes, a patch can be delivered instead of waiting for the next DCNM release. Modular Device Support helps to deliver and apply the DCNM patch releases. An authorized DCNM administrator can apply the patch to the production setup. Patch releases are applicable for the following scenarios:
-
Support any new hardware, like chassis or line cards
-
Support latest NX-OS versions
-
Support critical fixes as patches
To view the patch details from Cisco DCNM Web UI, perform the following steps:
Procedure
Step 1 |
Choose Administration > DCNM Server > Modular Device Support. You see the DCNM Servers column on the left in the window and Modular Device support information window on the right. |
Step 2 |
Expand DCNM Servers to view all the DCNM servers. It includes the list of patches installed along with the version number, corresponding platforms supported, chassis supported, NX-OS version supported, PID supported, backup directory and the last patch deployment time in the Modular Device support information table. |

When the fabric is first discovered and if the switch does not have a valid switch-based license, a license is automatically assigned to the fabric from the file license pool until no more licenses are left in the pool. If you have an existing fabric and a new switch is added to the fabric, the new switch is assigned a license if one is available in the file license pool and if it does not already have a switch-based license.
After you register smart license, if you click Assign License for a switch that does not have a permanent license, a smart license is assigned to the switch. The priority of licenses that are assigned are in the following order:
-
Permanent
-
Smart
-
Eval
Disabling smart licensing unassigns licenses of switches that were smart-licensed.
The evaluation license is assigned for switches that do not support smart licensing. The license state is Eval and the license type is DCNM-Server. See Cisco DCNM Licensing Guide, Release 11.x to view the list of switches that support smart licensing.
