Introduction

The Cisco Application Centric Infrastructure (ACI) is an architecture that allows the application to define the networking requirements in a programmatic way. This architecture simplifies, optimizes, and accelerates the entire application deployment lifecycle. Cisco Application Policy Infrastructure Controller (APIC) is the software, or operating system, that acts as the controller.

This document describes the features, issues, and limitations for the Cisco APIC software. For the features, issues, and limitations for the Cisco NX-OS software for the Cisco Nexus 9000 series switches, see the Cisco Nexus 9000 ACI-Mode Switches Release Notes, Release 13.2(10).

3.2(10e) and later

CSCvi20535

When a VRF table is configured to receive leaked external routes from multiple VRF tables, the Shared Route Control scope to specify the external routes to leak will be applied to all VRF tables. This results in an unintended external route leaking. This is an enhancement to ensure the Shared Route Control scope in each VRF table should be used to leak external routes only from the given VRF table.

CSCvn07827

Permament License Reservation (PLR) fails after upgrading to a Cisco APIC 4.0 release.

3.2(10e) and later

CSCvo24284

Fault delegates are raised on the Cisco APIC, but the original fault instance is already gone because the affected node has been removed from the fabric.

3.2(10e) and later

CSCvp01778

Access policy resolutions reveal unexpected results due to the existence of connectivity filters that are hidden from the UI. Depending on the VLANs tied to the AEPs/domains, this can result in unexpected outages as VLANs are pulled and 'invalid path' faults are flagged.

3.2(10e) and later

CSCvp24142

The Nginx process generates cores on the switches and the process will restart automatically. The core file from the switches gets collected and moved to the APIC, which drains the memory. You might need to remove the collected core files manually from the APIC to free up space.

3.2(10e) and later

CSCvq57942

In a RedHat OpenStack platform deployment running the Cisco ACI Unified Neutron ML2 Plugin and with the CompHosts running OVS in VLAN mode, when toggling the resolution immediacy on the EPG<->VMM domain association (fvRsDomAtt.resImedcy) from Pre-Provision to On-Demand, the encap VLANs (vlanCktEp mo's) are NOT programmed on the leaf switches.

This problem surfaces sporadically, meaning that it might take several resImedcy toggles between PreProv and OnDemand to reproduce the issue.

3.2(10e) and later

CSCvq63415

Disabling dataplane learning is only required to support a policy-based redirect (PBR) use case on pre-"EX" leaf switches.  There are few other reasons otherwise this feature should be disabled.  There currently is no confirmation/warning of the potential impact that can be caused by disabling dataplane learning.

3.2(10e) and later

CSCvq74727

When making a configuration change to an L3Out (such as contract removal or addition), the BGP peer flaps or the bgpPeerP object is deleted from the leaf switch.  In the leaf switch policy-element traces, 'isClassic = 0, wasClassic =1' is set post-update from the Cisco APIC.

When physical domains and external routed domains are attached to a security domain, these domains are mapped as associated tenants instead of associated objects under Admin > AAA > security management > Security domains.

3.2(10e) and later

CSCvs55753

A Cisco ACI leaf switch does not have MP-BGP route reflector peers in the output of "show bgp session vrf overlay-1". As a result, the switch is not able to install dynamic routes that are normally advertised by MP-BGP route reflectors. However, the spine switch route reflectors are configured in the affected leaf switch's pod, and pod policies have been correctly defined to deploy the route reflectors to the leaf switch. Additionally, the bgpPeer managed objects are missing from the leaf switch's local MIT.

The eventmgr database size may grow to be very large (up to 7GB). With that size, the Cisco APIC upgrade will take 1 hour for the Cisco APIC node that contains the eventmgr database.

In rare cases, this could lead to a failed upgrade process, as it times out while working on the large database file of the specified controller.

3.2(10e) and later

CSCvt13978

VPC protection created in prior to the 2.2(2e) release may not to recover the original virtual IP address after fabric ID recovery. Instead, some of vPC groups get a new vIP allocated, which does not get pushed to the leaf switch. The impact to the dataplane does not come until the leaf switch had a clean reboot/upgrade, because the rebooted leaf switch gets a new virtual IP that is not matched with a vPC peer. As a result, both sides bring down the virtual port channels, then the hosts  behind the vPC become unreachable.

3.2(10e) and later

CSCvt19061

Updating the interface policy group breaks LACP if eLACP is enabled on a VMM domain. If eLACP was enabled on the domain,  Creating, updating, or removing an interface policy group with the VMM AEP deletes the basic LACP that is used by the domain.

3.2(10e) and later

CSCvt37066

When migrating an EPG from one VRF table to a new VRF table, and the EPG keeps the contract relation with other EPGs in the original VRF table. Some bridge domain subnets in the original VRF table get leaked to the new VRF table due to the contract relation, even though the contract does not have the global scope and the bridge domain subnet is not configured as shared between VRF tables. The leaked static route is not deleted even if the contract relation is removed.

For an EPG containing a static leaf node configuration, the Cisco APIC GUI returns the following error when clicking the health of Fabric Location:

Invalid DN topology/pod-X/node-Y/local/svc-policyelem-id-0/ObservedEthIf, wrong rn prefix ObservedEthIf at position 63

3.2(10e) and later

CSCvu74566

There is a BootMgr memory leak on a standby Cisco APIC. If the BootMgr process crashes due to being out of memory, it continues to crash, but system will not be rebooted. After the standby Cisco APIC is rebooted by hand, such as by power cycling the host using CIMC, the login prompt of the Cisco APIC will be changed to localhost and you will not be able to log into the standby Cisco APIC.

3.2(10e) and later

CSCvv25475

After a delete/add of a Cisco ACI-managed DVS, dynamic paths are not programmed on the leaf switch and the compRsDlPol managed object has a missing target. The tDn property references the old DVS OID instead of the latest value.# moquery -c compRsDlPol

CSCvv62861

A leaf switch reloads due to an out-of-memory condition after changing the contract scope to global.

3.2(10e) and later

CSCvy30453

For a Cisco ACI fabric that is configured with fabricId=1, if APIC3 is replaced from scratch with an incorrect fabricId of "2," APIC3's DHCPd will set the nodeRole property to "0" (unsupported) for all dhcpClient managed objects. This will be propagated to the appliance director process for all of the Cisco APICs. The process then stops sending the AV/FNV update for any unknown switch types (switches that are not spine nor leaf switches). In this scenario, commissioning/decommissioning of the Cisco APICs will not be propagated to the switches, which causes new Cisco APICs to be blocked out of the fabric.

Another symptom is that the "acidag fnvread" command's output has a value of "unknown" in the role column.

3.2(10e) and later

CSCvy47145

A leaf switch experiences an SDKHAL crash when a summary route is added that is a host IP address in the subnet instead of the actual subnet boundary. Example: 10.10.10.1/24 summary address is entered instead of 10.10.10.0/24.

This summary route is added after a policy prefix for the actual subnet (10.10.10.0/24) is created.

The SDK hal crash will also result in other DME/process crashes for ipfib, epmc, aclqos, and eltmc.

A Cisco ACI leaf switch will install the subnet IP address as shown below, but it will not advertise this to the peer. A proper subnet is advertised to the peer router.

10.10.10.1/24, ubest/mbest: 1/0

Deleting a vPC does not clean up the allocated IP address from DHCPD DME.

3.2(10e)

CSCvp26599

When the VTEP IP address is changed on Cisco ACI Virtual Edge, a new ODev object gets created, but the old ODev is not deleted and the old ODev becomes stale. Due to this, the endpoints are still shown under the stale ODev. As a result, the traffic is impacted for those endpoints that are under the stale ODev.

Also, if a new Cisco ACI Virtual Edge comes up and happens to have the same VTEP IP address as the old ODev, the traffic will also be impacted behind the new Cisco ACI Virtual Edge. This is because the stale VTEP entry still exists on the leaf switch, and the leaf switch will reject the traffic saying "tunnel IP already exists" (bounce entry).

When the SSD file system (used by the Cisco APIC database) becomes read-only, the upgrade utility should catch such issues and abort the upgrade. This would allow the user to see the upgrade failure and triage the issue.  Currently, upgrade utility continues the data conversion and eventually reboots, which causes all configurations to be lost.

Creating or deleting a fabricSetupP policy results in an inconsistent state.

3.2(10e) and later

CSCva60439

After a pod is created and nodes are added in the pod, deleting the pod results in stale entries from the pod that are active in the fabric. This occurs because the Cisco APIC uses open source DHCP, which creates some resources that the Cisco APIC cannot delete when a pod is deleted.

3.2(10e) and later

CSCva86794

When a Cisco APIC cluster is upgrading, the Cisco APIC cluster might enter the minority status if there are any connectivity issues. In this case, user logins can fail until the majority of the Cisco APICs finish the upgrade and the cluster comes out of minority.

3.2(10e) and later

CSCva97082

When downgrading to a 2.0(1) release, the spines and its interfaces must be moved from infra L3out2 to infra L3out1. After infra L3out1 comes up, delete L3out2 and its related configuration, and then downgrade to a 2.0(1) release.

CSCvh93612

If two intra-EPG deny rules are programmed—one with the class-eq-deny priority and one with the class-eq-filter priority—changing the action of the second rule to "deny" causes the second rule to be redundant and have no effect. The traffic still gets denied, as expected.

3.2(10e) and later

CSCvj90385

With a uniform distribution of EPs and traffic flows, a fabric module in slot 25 sometimes reports far less than 50% of the traffic compared to the traffic on fabric modules in non-FM25 slots.

3.2(10e) and later

CSCvq39764

When you click Restart for the Microsoft System Center Virtual Machine Manager (SCVMM) agent on a scaled-out setup, the service may stop. You can restart the agent by clicking Start.

CSCvr57103

The CiscoAVS_4.10-5.2.1.SV3.4.10-pkg  package has signature issues during installation.

3.2(10e) and later

N/A

In a multipod configuration, before you make any changes to a spine switch, ensure that there is at least one operationally "up" external link that is participating in the multipod topology. Failure to do so could bring down the multipod connectivity. For more information about multipod, see the Cisco Application Centric Infrastructure Fundamentals document and the Cisco APIC Getting Started Guide.

3.2(10e) and later

N/A

With a non-english SCVMM 2012 R2 or SCVMM 2016 setup and where the virtual machine names are specified in non-english characters, if the host is removed and re-added to the host group, the GUID for all the virtual machines under that host changes. Therefore, if a user has created a micro segmentation endpoint group using "VM name" attribute specifying the GUID of respective virtual machine, then that micro segmentation endpoint group will not work if the host (hosting the virtual machines) is removed and re-added to the host group, as the GUID for all the virtual machines would have changed. This does not happen if the virtual name has name specified in all english characters.

3.2(10e) and later

N/A

A query of a configurable policy that does not have a subscription goes to the policy distributor. However, a query of a configurable policy that has a subscription goes to the policy manager. As a result, if the policy propagation from the policy distributor to the policy manager takes a prolonged amount of time, then in such cases the query with the subscription might not return the policy simply because it has not reached policy manager yet.

3.2(10e) and later

N/A

Cisco ACI vCenter Plug-in: Uninstall is not working; remains present in the GUI. After you uninstall the Cisco ACI vCenter Plug-in, it remains visible in the VMware vCenter UI. Restart the VMware vCenter Server to update the UI.

3.2(10e) and later

N/A

When there are silent hosts across sites, ARP glean messages might not be forwarded to remote sites if a 1st generation ToR switch (switch models without -EX or -FX in the name) happens to be in the transit path and the VRF is deployed on that ToR switch, the switch does not forward the ARP glean packet back into the fabric to reach the remote site. This issue is specific to 1st generation transit ToR switches and does not affect 2nd generation ToR switches (switch models with -EX or -FX in the name). This issue breaks the capability of discovering silent hosts.

·         Contracts using matchDscp filters are only supported on switches with "EX" on the end of the switch name. For example, N9K-93108TC-EX.

·         When the fabric node switch (spine or leaf) is out-of-fabric, the environmental sensor values, such as Current Temperature, Power Draw, and Power Consumption, might be reported as "N/A." A status might be reported as "Normal" even when the Current Temperature is "N/A."

·         Switches without -EX or a later designation in the product ID do not support Contract filters with match type "IPv4" or "IPv6." Only match type "IP" is supported. Because of this, a contract will match both IPv4 and IPv6 traffic when the match type of "IP" is used.
