Cisco Network Visibility Application for APIC-EM Release Notes, Release 1.4.0.x
This document describes the features, limitations, and bugs in Cisco Network Visibility applications (Discovery, Inventory, and Host), Release 1.4.0.x.
Along with Cisco Network Visibility, Cisco APIC-EM supports the following additional applications:
Cisco Path Trace
Cisco Network PnP
For information about the Cisco APIC-EM controller infrastructure (system requirements, security, licensing, supported multi-host configurations, and so on) and the other Cisco APIC-EM applications, see their corresponding release notes at the following URL:
software release provides the following new network visibility apps (Discovery,
Inventory, Host) features and functions:
Command Runner—Allows you to send CLI commands to selected devices. Currently, show and other read-only commands are permitted.
Update Polling Interval—Allows you to update the polling interval at the global level for all devices on the Settings > Polling Interval page or at the device level for a specific device in the Device Inventory window. When you set the polling interval at the device level, that value takes precedence over the global polling interval value.
Resync (Resynchronize Devices)—Allows you to immediately poll the selected device for updated information and status. The device information and status are updated in the inventory.
Update Credentials—Allows you to change the discovery credentials of selected devices.
IP Device Tracking (IPDT) Support—If enabled on devices, IPDT retrieves host information during the discovery process.
Supported Platforms and Software Requirements
For information about the network devices and software versions that Network Visibility supports, see Cisco Network Visibility Application for APIC-EM Supported
Installing or Upgrading Network Visibility
The Network Visibility image is built into the APIC-EM controller image. When you install or upgrade to APIC-EM 1.4.0.x, the Network Visibility Release 1.4.0.x is installed or upgraded as well.
After installing or upgrading the APIC-EM software, you can begin to use Network Visibility immediately. For any of the following information, see these sources:
Table 1 Information Sources for Installing or Upgrading Network Visibility
The Command Runner application is installed. However, when you enable the application in the Admin > App Management window and navigate away from the window before the enable operation is completed, the Command Runner button does not display on the Device Inventory window. The opposite scenario may also occur. You disable the application, and navigate away from the App Management window, and the Command Runner button does not disappear from the Device Inventory window.
Navigate to the Admin > App Management window and toggle the Enabled/Disabled button. If the current state is enabled, disable the application. If the current state is disabled, enable the application. Then enable or disable the application again (to achieve your original intent). Do not navigate away from the window until the operation is completed and the success banner displays.
If you shutdown port channels or member interfaces and rediscover a device with IPDT turned on, APIC configures IPDT on them. Then, if you bring the port channels or interfaces up (no shutdown), the device learns the IP addresses of its neighbor interfaces.
Do not configure IPDT on port channels or member interfaces when they are functionally down (shutdown).
Cisco APIC-EM does not apply IPDT configurations to devices running Cisco IOS XE 16.x without the SISF-Based Device-Tracking CLI.
On devices running Cisco IOS XE 16.x, migrate to SISF-Based Device-Tracking CLI. Then on Cisco APIC-EM, enable IPDT Autoconfig in admin > Settings > Device Controllability, delete the devices from inventory, and rediscover them.
The following table lists the resolved caveats for this release.
For a list of caveats resolved in an earlier software release, see the Cisco APIC-EM release notes for that specific release.
The Cisco Catalyst 4000 with Cisco IOS image version 3.8.x/3.9.x fails to go into a managed state (inventory collection). This occurs when the Cisco IOS image version is greater than or equal to 3.8.x.
Use a Cisco IOS-XE image version less than or equal to 3.7.x.
After upgrading to Cisco APIC-EM version 1.3.x, you will still have your discovery credentials available from your previous installation. If you run a legacy job specific discovery, then you may receive an error message.
Perform one of the following:
Select and only run a global discovery.
Select and run a global discovery with the job specific discovery.
To search for a specific bug,
enter the bug ID in the Search For field and press
To search for bugs in the current release:
In the Search For field, enter APIC-EM and press
Return. (Leave the other fields empty.)
When the search results are displayed, use the filter tools to
find the types of bugs you are looking for. You can search for bugs by modified
date, status, severity, and so forth.

Limitations and Restrictions
The Network Visibility application has the following limitations and restrictions.
Refer to the other Cisco APIC-EM app release notes or Cisco APIC-EM controller release notes for information about any other app or infrastructure-specific issues.
HTTP and HTTPS are not supported for device discovery for this release.
There is a 255 character limit when entering a multi-range IP address for a Discovery job. The Discovery job will fail if you enter more than 255 characters for a multi-range IP address.
The IP Device Tracking (IPDT) controllability feature is provided as a static configuration that is pushed to devices within your network during a discovery. The IPDT controllability feature overwrites the current state of IPDT configurations on the devices. If you do not want the existing IPDT configurations on the devices to be disturbed, you need to disable the IPDT controllability feature in the APIC-EM Settings. To do this, from the Global toolbar, click admin (shown as admin with the gear icon) > Settings > Device Controllability. In the Device Controllability window, turn off IPDT autoconfiguration by selecting No for IPDT Autoconfig.
