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 life cycle.
The Cisco Application Centric Infrastructure Fundamentals guide provides complete details about the ACI, including a glossary of terms that are used in the ACI.
Compatibility Information
This release supports the following Cisco APIC servers:
| Product ID |
Description |
| APIC-L1 |
Cisco APIC with large CPU, hard drive, and memory configurations (more than 1000 edge ports) |
| APIC-L2 |
Cisco APIC with large CPU, hard drive, and memory configurations (more than 1000 edge ports) |
| APIC-M1 |
Cisco APIC with medium-size CPU, hard drive, and memory configurations (up to 1000 edge ports) |
| APIC-M2 |

The following list includes general compatibility information:
■ This release supports the hardware and software listed on the ACI Ecosystem Compatibility List document and the software listed as follows:
— Cisco NX-OS Release 12.0(2)
— Cisco AVS, Release 5.2(1)SV3(2.2)
For more information about the supported AVS releases, see the AVS software compatibility information in the Cisco Application Virtual Switch Release Notes at the following URL:
— Cisco UCS Manager software release 2.2(1c) or later is required for the Cisco UCS Fabric Interconnect and other components, including the BIOS, CIMC, and the adapter
See the ACI Ecosystem Compatibility List document at the following URL:
■ The breakout of 40G ports to 4x10G on the N9332PQ switch is not supported in ACI-Mode.
■ To connect the N2348UPQ to ACI leaf switches, the following options are available:
— Directly connect the 40G FEX ports on the N2348UPQ to the 40G switch ports on the N9332PQ switch
— Break out the 40G FEX ports on the N2348UPQ to 4x10G ports and connect to the N9396PX or N9372PX switches
■ Connecting the APIC (the controller cluster) to the ACI fabric requires a 10G interface on the ACI leaf. You cannot connect the APIC directly to the N9332PQ ACI Leaf.
■ This release supports the following firmware:
— 1.5(4e) CIMC HUU iso
— 2.0(3i) CIMC HUU iso (recommended)
■ Beginning with Cisco Application Virtual Switch (AVS) release 5.2(1)SV3(1.10), you can connect service virtual machines that are part of Layer 4 to Layer 7 service graphs to AVS. Layer 4 to Layer 7 service graphs for Cisco AVS can be configured for service virtual machines that are in VLAN mode. By using two AVS VMM domains (one with VLAN and one with VXLAN), you can have a virtual machine in VXLAN mode that is protected by service graphs that are using the service virtual machine in VLAN mode.
■ This release supports VMM Integration and VMware Distributed Virtual Switch (DVS) 6.x. For more information about guidelines for upgrading VMware DVS from 5.x to 6.x and VMM integration, see the Cisco ACI Virtualization Guide, Release 2.0(2) at the following URL:
■ This release supports the Microsoft System Center Virtual Machine Manager (SCVMM) Update Rollup 9 and 10 releases, and the Microsoft Windows Azure Pack Update Rollup 9 and 10 releases.
■ This release supports the partner packages specified in the L4-L7 Compatibility List Solution Overview document at the following URL:
https://www.cisco.com/c/en/us/solutions/data-center-virtualization/application-centric-infrastructure/solution-overview-listing.html
■ This release supports Adaptive Security Appliance (ASA) device package version 1.2.5.5 or later.
■ If you are running a Cisco Adaptive Security Virtual Appliance (ASAv) version that is prior to version 9.3(2), you must configure SSL encryption as follows:
(config)# ssl encryption aes128-sha1
■ A known issue exists with the Safari browser and unsigned certificates, which applies when connecting to the APIC GUI. For more information, see the Cisco APIC Getting Started Guide.
■ For information about APIC compatibility with UCS Director, see the appropriate Cisco UCS Director Compatibility Matrix document at the following URL:
Usage Guidelines
This section lists usage guidelines for the APIC software.
■ The APIC GUI includes an online version of the Quick Start guide that includes video demonstrations.
■ The infrastructure IP address range must not overlap with other IP addresses used in the fabric for in-band and out-of-band networks.
■ The APIC does not provide IPAM services for tenant workloads.
■ To reach the APIC CLI from the GUI: select System > Controllers, highlight a controller, right-click and select "launch SSH". To get the list of commands, press the escape key twice.
■ In some of the 5-minute statistics data, the count of ten-second samples is 29 instead of 30.
■ For the following services, use a DNS-based host name with out-of-band management connectivity. IP addresses can be used with both in-band and out-of-band management connectivity.
— Syslog server
— Call Home SMTP server
— Tech support export server
— Configuration export server
— Statistics export server
■ Both leaf and spine switches can be managed from any host that has IP connectivity to the fabric.
■ If an IP address is learned on one of two endpoints for which you are configuring an atomic counter policy, you should use an IP-based policy and not a client endpoint-based policy.
■ When configuring two Layer 3 external networks on the same node, the loopbacks need to be configured separately for both Layer 3 networks.
■ All endpoint groups (EPGs), including application EPGs and Layer 3 external EPGs, require a domain. Interface policy groups must also be associated with an Attach Entity Profile (AEP), and the AEP must be associated with domains. Based on the association of EPGs to domains and of the interface policy groups to domains, the ports and VLANs that the EPG uses are validated. This applies to all EPGs including bridged Layer 2 outside and routed Layer 3 outside EPGs. For more information, see the Cisco Fundamentals Guide and the KB: Creating Domains, Attach Entity Profiles, and VLANs to Deploy an EPG on a Specific Port article.
Note: When creating static paths for application EPGs or Layer 2/Layer 3 outside EPGs, the physical domain is not required. Upgrading without the physical domain will raise a fault on the EPG stating “invalid path configuration.”
■ An EPG can only associate with a contract interface in its own tenant.
■ User passwords must meet the following criteria:
— Minimum length is 8 characters
— Maximum length is 64 characters
— Fewer than three consecutive repeated characters
— At least three of the following character types: lowercase, uppercase, digit, symbol
— Cannot be easily guessed
— Cannot be the username or the reverse of the username
— Cannot be any variation of “cisco”, “isco”, or any permutation of these characters or variants obtained by changing the capitalization of letters therein
■ The power consumption statistics are not shown on leaf node slot 1. You must view the statistics from any other node.
■ For Layer 3 external networks created through the API or Advanced GUI and updated through the CLI, protocols need to be enabled globally on the external network through the API or Advanced GUI, and the node profile for all the participating nodes needs to be added through the API or Advanced GUI before doing any further updates through the CLI.
■ For Layer 3 external networks created through the Basic GUI or CLI, you should not to update them through the API. These external networks are identified by names starting with “__ui_”.
■ The output from "show" commands issued in the NX-OS-style CLI are subject to change in future software releases. Cisco does not recommend using the output from the show commands for automation.
■ The CLI is supported only for users with administrative login privileges.
■ Do not separate virtual private cloud (vPC) member nodes into different configuration zones. If the nodes are in different configuration zones, then the vPCs’ modes become mismatched if the interface policies are modified and deployed to only one of the vPC member nodes.
■ If you defined multiple login domains, you can choose the login domain that you want to use when logging in to an APIC. By default, the domain drop-down list is empty, and if you do not choose a domain, the DefaultAuth domain is used for authentication. This can result in login failure if the username is not in the DefaultAuth login domain. As such, you must enter the credentials based on the chosen login domain.
■ A firmware maintenance group should contain max of 80 nodes.
■ When contracts are not associated with an endpoint group, DSCP marking is not supported for a VRF with a vzAny contract. DSCP is sent to a leaf along with the actrl rule, but a vzAny contract does not have an actrl rule. Therefore, the DSCP value cannot be sent.
■ When creating a vPC domain between two leaf switches, both switches must be in the same switch generation. Switches not in the same generation are not compatible vPC peers. The generations are as follows:
o Generation 1—Cisco Nexus N9000K switches without “EX” on the end of the switch name; for example, N9K-9312TX
o Generation 2—Cisco Nexus N9K switches with “EX” on the end of the switch model name; for example, N9K-93108TC-EX
■ The Cisco Discovery Protocol (CDP) is not supported in policies that are used on FEX interfaces.
■ ACI does not support a class E address as a VTEP address.
■ If the communication between the APIC and vCenter is impaired, some functionality is adversely affected. The APIC relies on the pulling of inventory information, updating vDS configuration, and receiving event notifications from the vCenter for performing certain operations.
■ When you create an access port selector in a leaf interface rofile, the fexId property is configured with a default value of 101 even though a FEX is not connected and the interface is not a FEX interface. The fexId property is only used when the port selector is associated with an infraFexBndlGrp managed object.

New and Changed Information
This section lists the new and changed features in this release and includes the following topics:
New Software Features
Table 3 lists the new software features in this release:
Table 2 New Software Features, Guidelines, and Restrictions
| Feature |
Description |
Guidelines and Restrictions |
| Auto Route Target for Layer 3 eVPN Services over Fabric WAN |
When creating a routed outside for eVPN, you can now choose “automatic” for the route target type. This feature implements automatic BGP route-target filtering on VRFs associated with this routed outside configuration. |
None. |
| Mis-cabling Protocol Enhancement |
A new Mis-cabling Protocol (MCP) configuration mode allows you to configure MCP to operate in a mode in which MCP PDUs are sent in all endpoint group VLANs to which a physical port belongs. For more information, see the Cisco Application Centric Infrastructure Fundamentals document. |
MCP is not supported on fabrix extender (FEX) host interface (HIF) ports. |
| Multiple L3Outs in Multipods |
Starting with the 2.0(2) release, one infra L3Out per POD is supported. Each POD can have one infra L3Out with a different OSPF area ID assigned to it. |
None. |
| Multipod QoS |
Support for preserving CoS and DSCP settings was added for multipod topologies. For more information, see the Cisco APIC and Multipod QoS document. |
None. |
| Proxy ARP |
Proxy ARP enables endpoints within a network or subnet to communicate with other endpoints without knowing the real MAC address of the endpoints. Proxy ARP is aware of the location of the traffic destination, and offers its own MAC address as the final destination instead. For more information, see the Cisco APIC Layer 2 Networking Configuration Guide |
None. |
| Syslog in NX-OS-Style CLI Format |
You can change the default display of syslogs to NX-OS-style CLI format. By default the syslog format is RFC 5424 compliant. For more information, see the Cisco APIC Troubleshooting Guide. |
None. |
| Tetration Image Download |
You can download the Cisco Tetration Analytics sensor software for installation on the switches in the APIC cluster. |
None. |
New Hardware Features
For new hardware features, see the Cisco Nexus 9000 ACI-Mode Switches Release Notes, Release 12.0(2) at the following location:
Changes in Behavior
This section lists changes in behavior in this release.
■ For port security, the maximum endpoints configured is now 12000.
■ Starting in the 2.0(2h) release, when configuring a BGP MD5 secret password through the CLI, you no longer are given an interactive prompt. This change enables you to automate configurations through the CLI, because the previous interactive prompt would break scripts.
■ You can now use the multipod feature on 9300-EX switches.
■ You can now use the multipod feature and Layer 3 EVPN services over fabric WAN feature together, but not on 9300-EX switches.

2.0(2f) and later |
|
| 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 |
2.0(2f) and later |

Description |
Exists in |
| The APIC does not validate duplicate IP addresses that are assigned to two device clusters. The communication to devices or the configuration of service devices might be affected. |
2.0(2f) and later |
|
| In some of the 5-minute statistics data, the count of ten-second samples is 29 instead of 30. |
2.0(2f) and later |
|
| The node ID policy can be replicated from an old appliance that is decommissioned when it joins a cluster. |
2.0(2f) and later |
|
| The DSCP value specified on an external endpoint group does not take effect on the filter rules on the leaf switch. |
2.0(2f) and later |
|
| The hostname resolution of the syslog server fails on leaf and spine switches over in-band connectivity. |
2.0(2f) and later |
|
| Following a FEX or switch reload, configured interface tags are no longer configured correctly. |
2.0(2f) and later |
|
| Switches can be downgraded to a 1.0(1x) version if the imported configuration consists of a firmware policy with a desired version set to 1.0(1x). |
2.0(2f) and later |
|
| If the APIC is rebooted using the CIMC power reboot, the system enters into fsck due to a corrupted disk. |
2.0(2f) and later |
|
| The Cisco APIC Service (ApicVMMService) shows as stopped in the Microsoft Service Manager (services.msc in control panel > admin tools > services). This happens when a domain account does not have the correct privilege in the domain to restart the service automatically. |
2.0(2f) and later |
|
| The traffic destined to a shared service provider endpoint group picks an incorrect class ID (PcTag) and gets dropped. |
2.0(2f) and later |
|
| Traffic from an external Layer 3 network is allowed when configured as part of a vzAny (a collection of endpoint groups within a context) consumer. |
2.0(2f) and later |
|
| Newly added microsegment EPG configurations must be removed before downgrading to a software release that does not support it. |
2.0(2f) and later |
|
| Downgrading the fabric starting with the leaf switch will cause faults such as policy-deployment-failed with fault code F1371. |
2.0(2f) and later |
|
| The OpenStack metadata feature cannot be used with ACI integration with the Juno release (or earlier) of OpenStack due to limitations with both OpenStack and Cisco’s ML2 driver. |
2.0(2f) and later |
|
| Transit traffic is dropped during ingress or egress when configured under the same Layer 3 Out with 0.0.0.0/0 security import subnet. This behavior is true for dynamic or static routing. To prevent this behavior, you must define more specific subnets and set the policy control enforcement preference to unenforced when configuring the associated VRF. |
2.0(2f) and later |
|
| Creating or deleting a fabricSetupP policy results in an inconsistent state. |
2.0(2f) and later |
|
| 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 APIC uses open source DHCP, which creates some resources that the APIC cannot delete when a pod is deleted. |
2.0(2f) and later |
|
| When an APIC cluster is upgrading, the 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 APICs finish the upgrade and the cluster comes out of minority. |
2.0(2f) and later |
|
| When downgrading from a 2.0(2) release 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. |
2.0(2f) and later |
§ 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.
