Supported Platforms and Software Requirements
For information about the network devices and software versions that Path Trace supports, see Cisco Path Trace Application for APIC-EM Supported
Installing or Upgrading Path Trace
The Path Trace image is built into the APIC-EM controller image. When you install or upgrade to the most recent version of APIC-EM 1.5.0.x, the Path Trace Release 1.5.0.x is installed or upgraded as well.
After installing or upgrading the APIC-EM software, you can begin to use Path Trace immediately because it is enabled by default. For any of the following information, see these sources:

Limitations and Restrictions
The Path Trace application has the following limitations and restrictions.
Refer to the other Cisco APIC-EM application release notes or Cisco APIC-EM controller release notes for information about any other application or infrastructure-specific issues.
Cisco Performance Routing or PfR is not supported with DMVPN tunnels.
VLAN ACLs ( VACLs) are not supported for this release. The Cisco APIC-EM is only supporting ACLs on VLAN.
For a NPR (Non Periodic Refresh) path scenario, after an upgrade, the controller will not refresh the path. Additionally, the statistics collection will stop. To continue the statistics collections, you must initiate a new path request.
A path trace from a host in a HSRP VLAN to a host in a non-HSRP VLAN that is connected to any of the HSRP routers is not supported.
Applying a performance monitor configuration through Cisco APIC-EM fails if there is a different performance monitor policy configuration on the interface. You should remove the performance monitor configuration on the interface and re-submit the path trace request.
Because the Cisco Wireless LAN controllers (WLCs) do not send SNMP mobility traps, note the following:
For a path trace request, the Cisco APIC-EM controller will not have the right egress virtual interface highlighted on any foreign WLC.
The path trace request will also not highlight any ACLs applied on the foreign WLC.
The workaround is to wait for inventory cycle to complete.
For Path Trace, Performance Monitor statistics are not supported for the Cisco ASR 1000 Series Aggregation Services Routers (Cisco IOS XE 16.3.1 image).
For Path Trace, Performance Monitor statistics are not supported for the Cisco Catalyst 3850 Switch (Cisco IOS XE 16.2.X and 16.3.1 images). This is because of a limitation on this version which is release noted by the product:
Cisco Adaptive Security Appliance (ASA) support is at a basic service level for this release, including Discovery and Inventory. There is no support for Cisco ASA in Path Trace and Topology, since Cisco ASA does not support CDP and it is not currently possible to identify link and path through the Cisco ASA appliance.
Object groups are not supported in an ACL trace.
