Alias, Annotations, and Tags

Several methods are provided for adding label metadata to objects.

For more information, see Cisco APIC System Management Configuration Guide, Release 5.2(x).

Automatic FPGA/EPLD/BIOS upgrade

Switches will automatically upgrade the FPGA/EPLD/BIOS based on the booting Cisco ACI switch image during a normal boot-up sequence for certain components, even if it’s not an upgrade operation performed through the APICs.

For more information, see the Cisco APIC Installation, Upgrade, and Downgrade Guide.

Disabling dataplane IP address learning per endpoint or subnet

You can disable dataplane IP address learning per endpoint or subnet. Previously, you could only disable dataplane IP address learning per VRF instance or bridge domain.

For more information, see the Cisco APIC Layer 3 Networking Configuration Guide, Release 5.2(x).

Dynamic MAC address detection for a Layer 3 policy-based redirect destination

You can configure any of the Layer 3 policy-based redirect (PBR) destinations without specifying a MAC address, which causes the leaf switches to use the Address Resolution Protocol (ARP) to determine the MAC address of the PBR next-hop. The benefit is that you do not need to check the MAC address of each PBR destination and an active-standby HA pair does not need to use a floating MAC address.

For more information, see Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, Release 5.2(x).

End of support for device packages

Device packages are no longer supported. There is no longer a managed mode for devices; all devices are effectively unmanaged.

All device package-related information was removed from the Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, Release 5.2(x).

EPG and tag selectors for ESGs

Endpoint group (EPG) selectors can add specific EPGs to an endpoint security group (ESG). Tag selectors can add objects to an ESG based on policy tags.

For more information, see the Cisco APIC Security Configuration Guide, Release 5.2(x). and  Cisco APIC System Management Configuration Guide, Release 5.2(x).

HTTP URI tracking

You can track service nodes using the HTTP URI.

For more information, see Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, Release 5.2(x).

MACsec support on N9K-X9716D-GX

MACsec is now supported on the Cisco N9K-X9716D-GX line card.

For a limitation regarding this new support, see the Cisco APIC Layer 2 Networking Configuration Guide, Release 5.2(x).

New DHCP faults

The Cisco APIC can now generate the following faults that inform you about issues in TEP IP address allocations with a dhcpPool object:

Note: If the APIC generates these faults suddenly after an upgrade, this does not mean new issues were introduced because of the upgrade. These faults were introduced to inform users proactively about an existing issue that was previously unnoticed until it causes an outage or negative impact.

Next-hop propagation supported with OSPF and static routes redistributed in BGP for floating L3Outs

Next-hop propagation is now supported with OSPF and static routes redistributed in BGP for floating L3Outs. Prior to this release, next-hop propagation was supported with BGP only for floating L3Outs.

For more information, see the Using Floating L3Out to Simplify Outside Network Connections knowledge base article.

Policy-based redirect destination in an L3Out

A policy-based redirect destination can now be in an L3Out.

For more information, see Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, Release 5.2(x).

Remote leaf peer-link support

Connect pairs of remote leaf switches directly to each other ("back-to-back") by fabric links to carry local east-west traffic.

For more information, see the Cisco APIC Layer 3 Networking Configuration Guide, Release 5.2(x).

Simplified ESG migration

EPG to ESG migration is simplified using EPG selectors.

For more information, see the Cisco APIC Security Configuration Guide, Release 5.2(x).

Site-of-Origin (SoO)

The SoO is a BGP extended community attribute that uniquely identifies the site from which a route is learned in order to prevent routing loops.

For more information, see the Cisco APIC Layer 3 Networking Configuration Guide, Release 5.2(x).

Software maintenance upgrade patches

You can install software maintenance upgrade (SMU) patches that contain fixes for specific defects. Because SMU patches can be released much more quickly than a more traditional patch release, you can resolve specific issues in a more timely manner.

For more information, see the Cisco APIC Installation, Upgrade, and Downgrade Guide.

Cisco APIC cluster connectivity to the fabric over a Layer 3 network

Support for a topology in which a standalone APIC cluster is separated from the Cisco ACI fabric by a Layer 3 inter-pod network (IPN).

For more information, see the Deploying APIC Cluster Connectivity to Fabric Over a Layer 3 Network knowledge base article.

Support for intra-EPG contracts on L3Out EPGs

Intra-EPG contracts are supported on L3Out EPGs. The action can be permit, deny, or redirect.

For more information, see Cisco APIC Basic Configuration Guide, Release 5.2(x).

Support for multiple next-hops to be propagated in the Cisco ACI fabric for redistributed routes in BGP for floating L3Outs

Support is available for multiple next-hops to be propagated in the Cisco ACI fabric for redistributed routes in BGP for floating L3Outs.

For more information, see Using Floating L3Out to Simplify Outside Network Connections.

Support for the Telecom PTP profile (G.8275.1)

The Telecom PTP profile (G.8275.1) is now supported.

For more information, see Cisco APIC System Management Configuration Guide, Release 5.2(x).

Synchronous Ethernet (SyncE)

Distributes high-quality clock frequency synchronization over Ethernet ports.

For more information, see Cisco APIC System Management Configuration Guide, Release 5.2(x).

VMware enhanced LACP support for virtual Layer 4 to Layer 7 services devices

Enhanced LACP on interfaces of Layer 4 to Layer 7 virtual service devices used in service graphs is now supported.

For more information, see Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, Release 5.2(x).

CSCvg81020

For strict security requirements, customers require custom certificates that have RSA key lengths of 3072 and 4096.

5.2(1g) and later

CSCvm56946

Support for local user (admin) maximum tries and login delay configuration.

5.2(1g) and later

CSCvs97029

All the external prefixes from VRF-A could be leaked to VRF-C even when an inter-VRF ESG leak route is configured for a specific prefix.

5.2(1g) and later

CSCvt99966

A SPAN session with the source type set to "Routed-Outside" goes down. The SPAN configuration is pushed to the anchor or non-anchor nodes, but the interfaces are not pushed due to the following fault: "Failed to configure SPAN with source SpanFL3out due to Source fvIfConn not available".

5.2(1g) and later

CSCvw69692

If a service graph gets attached to the inter-VRF contract after it was already attached to the intra-VRF contract, the pctag for the shadow EPG gets reprogrammed with a global value. The zoning-rule entries that matched the previous pctag as the source and EPG1 and EPG2 as the destination do not get reprogrammed and they remain in a stale status in the table.

Traffic between EPG1 and EPG2 gets broken as the packets flowing from the PBR get classified with the new global pctag.

5.2(1g) and later

CSCvx90225

The browser hangs when clicking on the alert bell in the header bar.

5.2(1g) and later

CSCvy13772

A standby APIC (in Layer 3 standalone mode) will not automatically upgrade along with the active Cisco APICs.

5.2(1g) and later

CSCvy17113

When there are two or more service graph associated contracts between the same pair of consumer and provider EPGs, and each contract is associated to a different Instp (by virtue of service graph configuration), imported/VRF-leaked Instp routes/subnets would not get cleaned up when one of those contracts is deleted from the list of contracts under the EPG. Imported routes /subnets would get cleaned up when the last contract between that EPG pair is deleted. There should be no impact to the traffic forwarding. This issue is about the cleanup of leaked routes.

5.2(1g) and later

CSCvy17504

When the OpFlexAgent moved from one vPC pair leaf switches to a new vPC pair, it may take up to 20 minutes for the OpFlexAgent detected the movement, and reconnect the OpFlex channel.  Ideally, this should be completed within a few seconds.

5.2(1g) and later

CSCvy21881

An upgrade fails due to an incompatible target version. The upgradeStatusStr for maintUpgJob is empty, due to which the GUI is not able to show the correct state.

5.2(1g) and later

CSCvy29992

On the Cisco APIC CLI, the "moconfig commit" command triggers a "No such file or directory" error. The command successfully commits the changes, but the fact that this error shows up results in confusion for the end user.

5.2(1g) and later

CSCvy33994

On the Cisco APIC CLI, using the "moset" command to set an managed object attribute to the same value results in the following error: [Errno 1] Operation not permitted.

5.2(1g) and later

CSCvy40511

Traffic from an endpoint under a remote leaf switch to an external node and its attached external networks is dropped. This occurs if the external node is attached to an L3Out with a vPC and there is a redistribution configuration on the L3Out to advertise the reachability of the external nodes as direct-attached hosts.

5.2(1g) and later

CSCvy46965

In the 5.2(1) release, an app gets stuck installing or there is fault for some containers not running.

5.2(1g) and later

CSCwa58709

The GIPo address is only visible on APIC 1 when using the command "cat /data/data_admin/sam_exported.config". The command output from the other APICs outputs do not show the GIPo address.

5.2(1g) and later

CSCwb93239

The GUI displays the following error:

      Failed, Local Upload Failure Msg (Request failed with status code 413).

5.2(1g) and later

CSCwc49449

When a maintenance policy has multiple switch nodes, such as vPC pair nodes, an SMU's uninstallation gets stuck in the "queued" state for one of the nodes.

5.2(1g) and later

CSCwc66053

Preconfiguration validations for L3Outs that occur whenever a new configuration is pushed to the Cisco APIC might not get triggered.

5.2(1g) and later

CSCwh98712

When running "show running-config" from API CLI, the command takes several minutes to complete. Several thousand API requests are seen in access.log querying ptpRsProfile on every static path.

5.2(1g) and later

CSCwi01316

In the following topology:

Tenant 1:

VRF 1 > EPG A, EPG B.  There is an any-to-any Intra VRF instance contract and EPG A and B are providers for an inter-VRF instance contract.

VRF 2 > L3Out or EPG. The VRF instance consumes the inter-VRF instance contract.

Traffic will unexpectedly get sent to the wrong rule when inter-VRF instance traffic is flowing.

5.2(1g) and later

CSCwi34095

App installation fails on the Cisco APIC with the error "Unable to add elasticsearch credentials".

This is seen for any app making use of Elasticsearch, such as Nexus Insight Cloud Connector.

5.2(1g) and later

CSCvs47602

A bridge domain route is not leaked on the service ToR switch after re-triggering the  service graph.

5.2(1g)

CSCvw12766

In a setup where there is already existing MDP confguration (spine and leaf nodes), after having deleted an MDP spine node, MDP tunnels and traffic might still be directed to that spine node. In the case of a new MDP spine node, the traffic might not get directed to the new spine node.

5.2(1g)

CSCvw69692

If a service graph gets attached to the inter-VRF contract after it was already attached to the intra-VRF contract, the pctag for the shadow EPG gets reprogrammed with a global value. The zoning-rule entries that matched the previous pctag as the source and EPG1 and EPG2 as the destination do not get reprogrammed and they remain in a stale status in the table.

Traffic between EPG1 and EPG2 gets broken as the packets flowing from the PBR get classified with the new global pctag.

5.2(1g)

CSCvw84947

The BGP loop prevention feature for the inter-VRF shared service case does function as expected upon upgradeing to the 5.2(1) release with existing contracts for a brownfield environment. There is no impact if new contracts are used.

5.2(1g)

CSCvx10921

A standby APIC disappears from the GUI after cluster convergence.

5.2(1g)

CSCvj26666

The "show run leaf|spine <nodeId>" command might produce an error for scaled up configurations.

5.2(1g) 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.

5.2(1g) 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.

5.2(1g) and later

CSCvq58953

One of the following symptoms occurs:

App installation/enable/disable takes a long time and does not complete.

Nomad leadership is lost. The output of the acidiag scheduler logs members command contains the following error:

Error querying node status: Unexpected response code: 500 (rpc error: No cluster leader)

5.2(1g) and later

CSCvr89603

The CRC and stomped CRC error values do not match when seen from the APIC CLI compared to the APIC GUI. This is expected behavior. The GUI values are from the history data, whereas the CLI values are from the current data.

5.2(1g) and later

CSCvs19322

Upgrading Cisco APIC from a 3.x release to a 4.x release causes Smart Licensing to lose its registration. Registering Smart Licensing again will clear the fault.

5.2(1g) and later

CSCvs77929

In the 4.x and later releases, if a firmware policy is created with different name than the maintenance policy, the firmware policy will be deleted and a new firmware policy gets created with the same name, which causes the upgrade process to fail.

5.2(1g) and later

CSCvx75380

svcredirDestmon objects get programmed in all of the leaf switches where the service L3Out is deployed, even though the service node may not be connected to some of the leaf switch.

There is no impact to traffic.

5.2(1g) and later

CSCvx78018

A remote leaf switch has momentary traffic loss for flushed endpoints as the traffic goes through the tglean path and does not directly go through the spine switch proxy path.

5.2(1g) and later

CSCvy07935

xR IP flush for all endpoints under the bridge domain subnets of the EPG being migrated to ESG. This will lead to a temporary traffic loss on remote leaf switch for all EPGs in the bridge domain. Traffic is expected to recover.

5.2(1g) and later

CSCvy34357

Starting with the 5.2(1) release, the following apps built with the following non-compliant Docker versions cannot be installed nor run:

·         ConnectivityCompliance 1.2

·         SevOneAciMonitor 1.0

5.2(1g) and later

CSCvy45358

The file size mentioned in the status managed object for techsupport "dbgexpTechSupStatus" is wrong if the file size is larger than 4GB.

5.2(1g) and later

N/A

If you are upgrading to Cisco APIC release 4.2(6o), 4.2(7l), 5.2(1g), or later, ensure that any VLAN encapsulation blocks that you are explicitly using for leaf switch front panel VLAN programming are set as "external (on the wire)." If these VLAN encapsulation blocks are instead set to "internal," the upgrade causes the front panel port VLAN to be removed, which can result in a datapath outage.

5.2(1g) and later

N/A

Beginning in Cisco APIC release 4.1(1), the IP SLA monitor policy validates the IP SLA port value. Because of the validation, when TCP is configured as the IP SLA type, Cisco APIC no longer accepts an IP SLA port value of 0, which was allowed in previous releases. An IP SLA monitor policy from a previous release that has an IP SLA port value of 0 becomes invalid if the Cisco APIC is upgraded to release 4.1(1) or later. This results in a failure for the configuration import or snapshot rollback.

The workaround is to configure a non-zero IP SLA port value before upgrading the Cisco APIC, and use the snapshot and configuration export that was taken after the IP SLA port change.

5.2(1g) and later

N/A

If you use the REST API to upgrade an app, you must create a new firmware.OSource to be able to download a new app image.

5.2(1g) 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.

5.2(1g) 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.

5.2(1g) 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.

5.2(1g) and later

N/A

When there are silent hosts across sites, ARP glean messages might not be forwarded to remote sites if a leaf switch without -EX or a later designation in the product ID happens to be in the transit path and the VRF is deployed on that leaf switch, the switch does not forward the ARP glean packet back into the fabric to reach the remote site. This issue is specific to transit leaf switches without -EX or a later designation in the product ID and does not affect leaf switches that have -EX or a later designation in the product ID. This issue breaks the capability of discovering silent hosts.

5.2(1g) and later

N/A

Typically, faults are generally raised based on the presence of the BGP route target profile under the VRF table. However, if a BGP route target profile is configured without actual route targets (that is, the profile has empty policies), a fault will not be raised in this situation.

5.2(1g) and later

N/A

MPLS interface statistics shown in a switch's CLI get cleared after an admin or operational down event.

5.2(1g) and later

N/A

MPLS interface statistics in a switch's CLI are reported every 10 seconds. If, for example, an interface goes down 3 seconds after the collection of the statistics, the CLI reports only 3 seconds of the statistics and clears all of the other statistics.

5.2(1g) and later

Cisco UCS M4-based Cisco APIC

The Cisco UCS M4-based Cisco APIC and previous versions support only the 10G interface. Connecting the Cisco APIC to the Cisco ACI fabric requires a same speed interface on the Cisco ACI leaf switch. You cannot connect the Cisco APIC directly to the Cisco N9332PQ ACI leaf switch, unless you use a 40G to 10G converter (part number CVR-QSFP-SFP10G), in which case the port on the Cisco N9332PQ switch auto-negotiates to 10G without requiring any manual configuration.

Cisco UCS M5-based Cisco APIC

The Cisco UCS M5-based Cisco APIC supports dual speed 10G and 25G interfaces. Connecting the Cisco APIC to the Cisco ACI fabric requires a same speed interface on the Cisco ACI leaf switch. You cannot connect the Cisco APIC directly to the Cisco N9332PQ ACI leaf switch, unless you use a 40G to 10G converter (part number CVR-QSFP-SFP10G), in which case the port on the Cisco N9332PQ switch auto-negotiates to 10G without requiring any manual configuration.

N2348UPQ

To connect the N2348UPQ to Cisco ACI leaf switches, the following options are available:

Directly connect the 40G FEX ports on the N2348UPQ to the 40G switch ports on the Cisco ACI leaf switches

Break out the 40G FEX ports on the N2348UPQ to 4x10G ports and connect to the 10G ports on all other Cisco ACI leaf switches.

Note: A fabric uplink port cannot be used as a FEX fabric port.
