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".

6.0(9c) and later

CSCwf48875

When using two different host profiles (for example UCS C-Series and UCS B-Series) to deploy NSX, the uplink policy will be different for the host profiles. In this case, using one uplink profile with two policies might cause traffic disruption for a non-default teaming policy.

6.0(9c) and later

CSCwp14876

Return PBR traffic dropped on Service Leaf after APIC upgrade due to actrlRule missing to allow traffic.

6.0(9d)

CSCwc50398

Licensemgr process crashes on node-1, with Smart license mode being "Direct connection to CSSM” under smart license settings.

6.0(9c) and 6.0(9d)

Users are unable to authenticate on APICs 1 and 2 via GUI after power event/reload of APIC, while authentication works on APIC 3. CLI access still works.

6.0(9d)

CSCwh41632

APIC controller upgrade will be shown as completed only after the post upgrade activities are completed.

6.0(9d)

CSCwn59662

After upgrading an ACI leaf, the GBP cache may miss some contracts, which can cause traffic disruptions for the affected EPGs. On the OSP/compute node, this issue may manifest as policy miss drops in OVS, specifically indicated by POL_TABLE MISS.

6.0(9d)

CSCwo45052

We should have proper validation for gipo. need to validate the following things:

1. valid range

2. valid subnet/mask

APIC obviously took the invalid address at the initial setup, whereas NXOS correctly rejects in multi-pod environment.

6.0(9d)

CSCwb66277

When trying to generate acllogPermitL3Flow, acllogDropL3Flow, acllogPermitL3Pkt or acllogDropL3Pkt, APIC returns to the user "Unable to deliver the message. Resolve timeout from (type/num/svc/shard) = switch:{switchId}:4:0".

6.0(9c)

CSCwb97455

switch nginx process would be blocked when query acllog records, either from visore or through CLI moquery. this is due to performance issue when querying those info and creating acllog mos on the fly. the main time consumer is query actrlRule when it is relatively large, around ~50K mos. If nginx is blocked, customer can not logging to switch for about 10-15 mins until nginx is timed out querying those acllog records.

6.0(9c)

CSCwh63412

Audit logs under System > History > Audit Logs are limited to the current logged in user. Only the user with the username admin can see the audit logs from all users, but other users despite having admin privileges cannot see the audit logs from other users. The audit logs under Tenants are visible to every user.

6.0(9c)

CSCwi05819

Export of techsupport, configuration backups, etc. does not work when the remote server is a Windows machine with SFTP because the GUI does not allow a remote path without a leading slash in the remote location object (`fileRemotePath.remotePath`).For instance, an example of a correct remote path for a Windows machine with SFTP is "C:/Users/Administrator/Downloads".However, the GUI enforces users to type "/C:/Users/Administrator/Downloads" instead, which fails with a fault F0053 and error "Upload failed, Destination access was denied".

6.0(9c)

CSCwi12805

The CLI command "show dcimgr repo sclass-maps" reports multiple translation rules stated as unformed. Those rules are not installed in the line card, which is not found by the CLI command "show plat int hal dci sclassmap".

6.0(9c)

CSCwi66761

The client Certificate Authenticate state is disabled but the browser still prompts for the certificate when the APIC GUI is accessed.

6.0(9c)

CSCwi76453

In L3Outs with BGP enabled, we cannot configure an IPv6 neighbor address with /127 and /128 prefix under the BGP Connectivity Profile, especially for physical interfaces. For example: fd00::/127.

The input box will be squared with red and display a red exclamation mark, but it does not give a warning in the pop-up text when you hover the mouse cursor on the exclamation mark. Also, the "Submit" button will be grayed out.

6.0(9c)

CSCwi80052

After a user changes the time zone from UTC to a local time zone in "System" > "System Setting" > "Date and Time", the time zone looks changed to the local time zone on the APIC GUI (For example, Asia/Tokyo).

But, the time zone attribute of the datetimeFormat managed object that manages time zone internally is still set to UTC.

6.0(9c)

CSCwi81236

When deploying an encapsulation VLAN on an EPG using AAEP, any subsequent VLAN you attempt to deploy under the same AAEP overwrites the existing VLAN, with no prior warning or notification.

6.0(9c)

CSCwk69242

When an APIC controller in one Pod is replaced by a standby controller from another Pod, the Static Node Management Address for Out-of-Band interface on the new active APIC (former standby APIC) is assigned to the "default" OOB EPG instead of the configured custom OOB EPG. As a result, the new active APIC might become unreachable through Out-of-Band.

CSCwm44776

If user defined tenant configuration uses the same VLAN as the infra VLAN then during the configuration you will see a fault F0467 about the VLAN encap being in use on the leaf that has the APIC infra VLAN deployed on the APIC connected interface. However, if the APIC interface goes down then the tenant VLAN gets programmed which results in the switch port not having the actual infra VLAN deployed. The interface shows unapproved controller for the connected APIC.

CSCwm48813

During the ACI switch SMU installation, the upgrade window fails to update the SMU version information in a timely manner.

Using the APIC GUI:

Step 1.Upload a SMU image: Navigate to Admin > Firmware > Images.

Step 2.Create a Switch upgrade policy: Proceed to Admin > Firmware > Switches > Actions > Create Update Group. Select a switch, then opt for "Software Maintenance Upgrade (Install)" and choose the previously uploaded SMU firmware. Initiate the download.

Step 3.Admin > Firmware > Switches > Click on the current status > Click Actions > Select Install and Reload.

Step 4.Maintain the upgrade window open and await the completion of the installation.

 Despite the installation being complete, the SMU Version column remains blank with "-",    and refreshing the page offers no help.

As per design, the ESG policies and intra-VRF routes (all BD subnets) are programmed on all nodes where the VRF is deployed upon ESG creation. In contra-VRF routes, when the last ESG associated with VRF is removed from the APIC, we expected respective BD subnets to be removed from all nodes where the BD/EPG is not deployed. However, this is not the case. The BD subnets remained on the nodes where the VRF is deployed.

VMMmgr process experiences a very high load for an extended period of time that impacts other operations that involve it.

The process may consume excessive amount of memory and get aborted. This can be confirmed with the command "dmesg -T | grep oom_reaper" if messages such as the following are reported:

         oom_reaper: reaped process 5578 (svc_ifc_vmmmgr.)

6.0(9c) and later

CSCwa78573

When the "BGP" branch is expanded in the Fabric > Inventory > POD 1 > Leaf > Protocols > BGP navigation path, the GUI freezes and you cannot navigate to any other page.

This occurs because the APIC gets large set of data in response, which cannot be handled by the browser for parts of the GUI that do not have the pagination.

However, if the VMM domain is used by Layer 4 to Layer 7 virtual services and the VMM domain is referencing a static VLAN pool, the services do not work and a fault is raised.

6.0(9c) and later

CSCwh92539

After upgrading a Cisco APIC from a release before 5.2(8) to release 6.0(7) or later, there is a loss of out-of-band management connectivity over IPv6 if the APIC has dual stack out-of-band management. However, IPv4 connectivity remains intact. This issue does not occur if the out-of-band management is only IPv4 or only IPv6.

6.0(9c) 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.

6.0(9c) 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.

6.0(9c) 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.

6.0(9c) 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.

6.0(9c) 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.

6.0(9c) 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.

6.0(9c) 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.

6.0(9c) 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.

6.0(9c) and later

N/A

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

6.0(9c) 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.

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.

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.
