New and Changed Information in Cisco DCNM, Release 11.5(1)
The following table provides an overview of the significant changes to this guide for this current release. The table does not provide an exhaustive list of all changes made to the guide or of the new features in this release.
Feature | Description | Where Documented |
Single-switch Configuration Restore |
You can restore configuration for a Cisco Nexus switch in external and LAN classic fabrics from the Cisco DCNM Web UI. The information you restore at switch-level is extracted from the fabric-level backups. The switch-level restoration does not restore fabric-level intents and other configurations applied using the fabric settings. Only switch-level intents are restored. |
|
EPLD Golden Upgrade |
From Cisco DCNM Release 11.5(1), DCNM supports EPLD golden upgrade as well. When you perform the EPLD upgrade, you have an option to choose the golden or primary region of the Nexus 9000 Series switches. You can view the EPLD golden upgrade notifications in the Events window. From the homepage of the Cisco DCNM Web UI, choose Monitor > Switch >Events. |
|
PTP Monitoring Application |
The Precision Time Protocol (PTP) is a time synchronization protocol for nodes that are distributed across a network. On a local area network, it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems. In DCNM, PTP Monitoring can be installed as an application. This PTP monitoring application, which can be previously installed in Media Controller deployment can now be installed in LAN Fabric deployment as a preview feature. We recommend that you do not deploy this feature in production environments. |
|
Support for Simplified CLI Configuration for Brownfield Deployment |
The Brownfield import in DCNM supports the simplified NX-OS VXLAN EVPN configuration CLIs. |
|
CloudSec Operational View |
You can use the CloudSec Operational View tab in DCNM to check the operational status of the CloudSec sessions if CloudSec is enabled on the MSD fabric. |
|
Sync up Out-of-Band Switch Interface Configurations with DCNM |
You can use the host_port_resync policy to sync up any out-of-band switch interface level configurations (via CLI) with Cisco DCNM and subsequently manage it. Additionally, the vPC pair configurations are automatically detected and paired. |

Support for MACsec in Easy Fabric and eBGP Fabric |
MACsec is supported in the Easy Fabric and eBGP Fabric on intra-fabric links. You need to enable MACsec on the fabric and on each required intra-fabric link to configure MACsec. Note that this is a preview feature in the Cisco DCNM Release 11.5(1). |
|
Interface Group |
You can create an interface group that allows grouping of host-facing interfaces at a fabric level. Specifically, you can create an interface group for physical Ethernet interfaces, L2 port-channels, and vPCs. You can attach or unattach multiple overlay networks to the interfaces in an interface group. |
|
L4-7 Services Enhancements |
The following enhancements are introduced in DCNM Release 11.5(1):
|
|
OpenStack Workload Visibility |
OpenStack plugin application is provided by DCNM that helps you to monitor OpenStack Clusters. You can get visibility with respect to the physical network connectivity and virtualized workloads, and debug VM networking specific issues within the context of the data center. Note that this is a preview feature in the Cisco DCNM Release 11.5(1). |
|
Support for L3 Gateway on Border for fabrics |
From Cisco DCNM Release 11.5(1), the Enable L3 Gateway on Border field is not available as part of the MSD network settings. You can enable a Layer 3 gateway on the border switches at a fabric level. |
|
Periodic report generation frequency |
|
|
Pre-provisioning a device |
From Cisco DCNM Release 11.5(1), extended configuration support to pre-provisioned devices. |
|
Enhanced Role-based Access control |
New user roles, device-upg-admin, and access-admin are added.
|
|
Switch-smart License |
From Cisco DCNM Release 11.5(1), new license type is added for switches. |
|
Inband Management in External Fabrics and LAN Classic Fabrics |
Cisco DCNM allows you to import or discover switches with inband connectivity for External and LAN Classic fabrics in Brownfield deployments only. Enable inband management, per fabric, while configuring or editing the Fabric settings. You cannot import or discover switches with inband connectivity using POAP. |
Inband Management in External Fabrics and LAN Classic Fabrics |
Precision Time Protocol for External Fabrics or LAN Classic Fabrics |
From Release 11.5(1), in the fabric settings for the External_Fabric_11_1 or LAN_Classic template, select the Enable Precision Time Protocol (PTP) check box to enable PTP across a fabric. |
Precision Time Protocol for External Fabrics and LAN Classic Fabrics |
Ability to Edit DNS, NTP Servers from the GUI |
Cisco DCNM allows you to modify few network parameters from the Web UI. Modifying these will overwrites the previously configured parameters. |
