5.3(1d) and later

CSCwe92155

After configuring syslog using TCP on port 59500, the logit was sent out normally and netstat showed that it was established. However, after aborting the connection from the syslog server side, the TCP connection went from ESTABLISHED to CLOSE_WAIT and disappeared from the APIC side.

5.3(1d) and later

CSCwe93045

There is general slowness when an application contacts the Cisco APIC cluster through the REST API. The same slowness is experienced when accessing using the Cisco APIC GUI.

5.3(1d) and later

During upgrade "deserialization error" is seen on APIC 1 PD.

5.3(1d) and later

CSCwh05135

Override vpc interface policy doesnot consistently take precedence over regular vpc interface policy. Upon a leaf reload, its quite random which policy takes precedence, and accordingly the vlans get programmed. If the override or regular AEP is missing the relevant domain association/vlans, then those vlans are not programmed causing outages.

5.3(1d) and later

CSCwh07037

An outage occurred because traffic coming from the TEPs was dropped by the receiving leaf switches with INFRA_ENCAP_SRC_TEP_MISS.

5.3(1d) and later

The API call /mqapi2/deployment.query.json?mode=getvmmCapInfo that is done against the Cisco APICs by an external management system takes too long to process.

5.3(1d) and later

CSCwh56716

When the Cisco APICs use Direct Connect to CSSM, running the "show license usage" command on APIC 1, 2, or 3 shows ACI_LEAF_ESS_10G 6 in use. When APICs 2 and 3 are restarted, this output is unchanged. When APIC 1 is restarted, the output becomes "No Licenses in use" on APICs 1, 2, and 3. The "Registering for Smart Licensing with Direct Connect to CSSM Using the GUI" process has to be done again.This was tested in the lab with Cisco APIC releases 5.2(6g), 5.2(7g), and 6.0(2j)

5.3(1d) and later

CSCwj13396

ACI switches show in maintenance with the CLI command "acidiag fnvread" on Cisco APIC, but they show "normal" in vsh and even top. System also shows In service.

- Switches do not show up in the GUI nor API for configurations, as APIC vectors it as in maintenance. This severely impacts the ability to make changes.

- Switches may continue to work normally even though no new configurations can be made on them.

5.3(1d) and later

CSCwj17966

The Cisco APIC bootmgr or appliance director allows an incorrect attribute/value update to be received in LLDP TLV due to miscabling.

5.3(1d) and later

CSCwj23752

Changing in the name of the remote-destination group stops the sending of syslog messages to the remote destination. Changing the port number or forwarding facility does not affect the sending of the messages. Only when the name is changed does the leaf switch stop sending the syslog messages. Enabling and disabling the policy does not resume the sending of the messages.

5.3(1d) and later

CSCwj38953

log_bin_decode crashes on distinguished name decoding failures.

5.3(1d) 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.

5.3(1d) and later

CSCvq58953

One of the following symptoms occurs:

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

5.3(1d) 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.

5.3(1d) and later

CSCvs19322

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

5.3(1d) 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.

5.3(1d) 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.

5.3(1d) and later

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.

5.3(1d) 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.

5.3(1d) and later

CSCvy10946

With the floating L3Out multipath recursive feature, if a static route with multipath is configured, not all paths are installed at the non-border leaf switch/non-anchor nodes.

5.3(1d) and later

CSCvz85579

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.)

5.3(1d) 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.

5.3(1d) and later

CSCwd45200

Hosting server details for AVE endpoints at the operational tab under the EPG is not updated after VM migration.

5.3(1d) and later

CSCwd51537

After changing a VM's name, the name does not get updated for endpoints in the Operational tab of an EPG.

5.3(1d) and later

CSCwk21572

License manager occasionally cores after image upgrade.

5.3(1d) 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.

5.3(1d) 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.

5.3(1d) 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.

5.3(1d) 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.

5.3(1d) 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.

5.3(1d) 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.

5.3(1d) 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.

5.3(1d) 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.

5.3(1d) and later

N/A

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

5.3(1d) 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.

5.3(1d) and later
