See the Cisco Network Insights Base Application for the Cisco Application Policy Infrastructure Controller Release Notes, Release 1.0.1.

N/A

Link level policies

You can now create link level policies under fabric policies. A link level policy applies to the fabric interfaces (leaf switch uplink ports and spine switch ports) at the link level and is used where there might be link noise or transient flaps. In the policy, you configure a link debounce interval. When there is a flap, the fabric interfaces will wait for the debounce interval to pass, then check the link status again to re-confirm the event. If the link is okay at this time, then the interfaces will remain up. The default debounce interval is 0 ms. We recommend a value of 100 ms, but you should choose a value that is appropriate to your fabric.

This feature was added in release 3.2(9f).

N/A

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(9h) and later

CSCvs81881

The Cisco APIC PSU voltage and amperage values are zero.

3.2(9f) and later

3.2(9f) and later

CSCvt93482

The per feature container for techsupport "objectstore_debug_info" fails to collect on spines due to invalid filepath.

Given filepath: more /debug/leaf/nginx/objstore*/mo | cat

Correct filepath: more /debug/spine/nginx/objstore*/mo | cat

TAC uses this file/data to collect information about excessive DME writes.

3.2(9f) and later

CSCvu12092

AVE is not getting the VTEP IP address from the Cisco APIC. The logs show a "pending pool" and "no free leases".

3.2(9f) and later

3.2(9b) and later

CSCvd66359

The Port ID LLDP Neighbors panel displays the port ID when the interface does not have a description. Example:  Ethernet 1/5, but if the interface has description, the Port ID property shows the Interface description instead of the port ID.

3.2(9b) and later

CSCve84297

A service cannot be reached by using the APIC out-of-band management that exists within the 172.17.0.0/16 subnet.

3.2(9b) and later

CSCvf70362

This enhancement is to change the name of "Limit IP Learning To Subnet" under the bridge domains to be more self-explanatory.

Original :

    Limit IP Learning To Subnet: [check box]

Suggestion :

    Limit Local IP Learning To BD/EPG Subnet(s): [check box]

3.2(9b) and later

CSCvg00627

A tenant's flows/packets information cannot be exported.

3.2(9b) and later

CSCvg35344

Requesting an enhancement to allow exporting a contract by right clicking the contract itself and choosing "Export Contract" from the right click context menu. The current implementation of needing to right click the Contract folder hierarchy to export a contract is not intuitive.

3.2(9b) and later

CSCvg70246

When configuring an L3Out under a user tenant that is associated with a VRF instance that is under the common tenant, a customized BGP timer policy that is attached to the VRF instance is not applied to the L3Out (BGP peer)  in the user tenant.

3.2(9b) 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.

3.2(9b) and later

CSCvi82903

When authenticating with the Cisco APIC using ISE (TACACS), all logins over 31 characters fail.

3.2(9b) and later

3.2(9b) and later

CSCvm83669

There is a VLAN overlapping scenario. After configuring new static ports and a physical domain under an existing EPG, there is a Layer 2 loop. This issue is due to an FD VLAN encapsulation mismatch on two leaf switches.

3.2(9b) and later

CSCvn07827

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

3.2(9b) 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(9b) 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(9b) 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(9b) and later

CSCvp26694

A leaf switch gets upgraded when a previously-configured maintenance policy is triggered.

3.2(9b) and later

3.2(9b) 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(9b) 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(9b) 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(9b) 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.

3.2(9b) and later

CSCvs57061

In a GOLF configuration, when an L3Out is deleted, the bridge domains stop getting advertised to the GOLF router even though another L3Out is still active.

3.2(9b) and later

CSCvs66244

The CLI command "show interface x/x switchport" shows VLANs configured and allowed through a port. However, when going to the GUI under Fabric > Inventory > node_name > Interfaces > Physical Interfaces > Interface x/x > VLANs, the VLANs do not show.

3.2(9b) and later

CSCvs76244

The tmpfs file system that is mounted on /data/log becomes 100% utilized.

3.2(9b) and later

CSCvt00796

The policymgr DME process can crash because of an OOM issue, and there are many pcons.DelRef managed objects in the DB.

3.2(9b) and later

CSCvt07565

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(9b) 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(9b) 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(9b) 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.

3.2(9b) and later

CSCvt40736

The login history of local users is not updated in Admin > AAA > Users > (double click on local user) Operational > Session.

3.2(9b) 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(9b) 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

CSCvp64280

A vulnerability in the fabric infrastructure VLAN connection establishment of the Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an unauthenticated, adjacent attacker to bypass security validations and connect an unauthorized server to the infrastructure VLAN.

The vulnerability is due to insufficient security requirements during the Link Layer Discovery Protocol (LLDP) setup phase of the infrastructure VLAN. An attacker could exploit this vulnerability by sending a malicious LLDP packet on the adjacent subnet to the Cisco Nexus 9000 Series Switch in ACI mode. A successful exploit could allow the attacker to connect an unauthorized server to the infrastructure VLAN, which is highly privileged. With a connection to the infrastructure VLAN, the attacker can make unauthorized connections to Cisco Application Policy Infrastructure Controller (APIC) services or join other host endpoints.

Cisco has released software updates that address this vulnerability. There are workarounds that address this vulnerability.

This advisory is available at the following link:

https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190703-n9kaci-bypass

3.2(9b)

CSCvp64857

A vulnerability in the REST API for software device management in Cisco Application Policy Infrastructure Controller (APIC) Software could allow an authenticated, remote attacker to escalate privileges to root on an affected device.

The vulnerability is due to incomplete validation and error checking for the file path when specific software is uploaded. An attacker could exploit this vulnerability by uploading malicious software using the REST API. A successful exploit could allow an attacker to escalate their privilege level to root. The attacker would need to have the administrator role on the device.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link:

Traffic to newly provisioned floating IP addresses is dropped for up to an hour.

3.2(9b)

CSCvq05143

Using a PBR service graph with ASA in two-arm mode. After upgrading from release 12.3(1) to 13.1 to 13.2(6i), the service graph (in the common tenant) has some faults. The service graph is working for previously-configured EPGs (verified by checking traffic that is redirected to the firewall), but new EPGs cannot be applied to the service graph. The service graph state is also "not applied".

One of the faults mentions that the service graph contract cannot be used as provider and consumer and that the contract is only supported in single-node PBR with one arm. The contract is not being applied in any vzAny consumer/provider. The "Epp not found. Retry or abort task" error appears in the policymanager. Adding an ARP filter on the contract does not trigger anything, although the modification is seen in the policy distributor.

If a switch upgrade is triggered after the series of steps outlined in this bug's conditions, the switch nodes may get stuck in a reboot loop where the bootscript process pushes the bootscript file (using DCHP), which tells the switch to boot into the default version. However, the APIC policy discovers the switch and finds that it has not yet been upgraded to the upgrade target version.

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.
