New Software Features

Feature

Description

Guidelines and Restrictions

COOP Endpoint Dampening

When malicious or erroneous behavior causes unnecessary endpoint updates, the COOP process can become overwhelmed, preventing the processing of valid endpoint updates. The rogue endpoint detection feature of the leaf switch can prevent many erroneous updates from reaching the spine. In cases where the rogue endpoint detection is inadequate, the COOP process invokes endpoint dampening. To relieve pressure on COOP, the spine asks all leaf switches to ignore updates from the misbehaving endpoint for a specified period.

For more information, see the Cisco APIC Basic Configuration Guide, Release 4.2(x).

None.

Enhancements for Match Prefix

Two new fields (From Prefix and To Prefix fields) are now available in the Match Prefix field to specify the mask range when you create a prefix match rule and enable aggregation.

For more information, see the Cisco APIC Layer 3 Networking Configuration Guide, Release 4.2(x).

None.

Filters-from-contract option in the service graph templates

The filters-from-contract option is available in the service graph templates using the Cisco APIC GUI. This option uses the specific filter of the contract subject where the service graph is attached, instead of the default filter for zoning-rules that do not include the consumer EPG class ID as the source or destination.

For more information, see the Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, Release 4.2(x).

None.

Increased range for equal-cost multi-path (ECMP) routing paths

The range for the maximum number of equal-cost paths for eBGP and iBGP load sharing is now from 1 to 64, with a default value of 16.

For more information, see the Cisco APIC Layer 3 Networking Configuration Guide, Release 4.2(x).

None.

Incremental enhancements to the read-only admin user capability on spine and leaf switches

Switches running the 14.2(3) release now support L1 access (read-only privilege for an admin user) for the following things:

■      acidiag fnvread command

■      vsh_lc with the show commands

■      Tech support collection

■      show events command

■      PCAP under the visibility and troubleshooting section

■      BGP advertised and received routes (show bgp ipv4 unicast neighor <neighbor ip> advertised-routes vrf <vrf name>)

■      CRC command to identify stomped CRC and genuine CRC

■      Read-only access to the log files, such as BGP, BFD, and IPv6

■      tcpdump command

None.

Python SDK (Cobra) support for Python 3.x and Wheel

The Cisco APIC Python SDK adds support for Python 3.6 and later. A Wheel installation package is now included in addition to the egg files.

None.

Rogue EP Control in the First Time Setup wizard

The Rogue EP Control option is now part of the First Time Setup wizard.

For more information, see the Cisco APIC Basic Configuration Guide, Release 4.2(x).

None.

Stomped CRC errors and traditional CRC errors

CRC align errors in interface counters are now broken out into stomped CRC errors and traditional CRC errors. Stomped CRC errors refer to frames that were received and cut-through switched before the FCS trailer was received. Rather than rewriting the CRC field based on the corrupted frame, the switch will insert a special value into the CRC that indicates the frame should be stomped by the end device or the first device in the path that does store-and-forward switching.

"CRC error" frames refer to corrupted frames that are dropped on the ingress interface and are not forwarded.

You can view the split in error statistics in the Cisco APIC GUI or by directly querying the eqptIngrCrcErrPkts object. Additionally you can view the statistics directly on the switch by running the "show interface" command.

None.

Support for custom EPG names for VMM domains

You can now give EPGs a custom name that carries over to a VMware vCenter port group or a Microsoft VM network. The feature is available for VMware vSphere Distributed Switch, Microsoft System Center Virtual Machine Manager (SCVMM), and Cisco ACI Virtual Edge. If you do not provide a custom name, the domain association assigns a name in the format of tenant|app_profile|epg_name for a port group or tenant|application|epg|domain for a VM network. However, if you enter a custom name for the EPG, the same name is applied to the port group or VM network.

For more information, see the "Custom EPG Names and Cisco ACI" chapter in the Cisco ACI Virtualization Guide, Release 4.2(x).

Giving an EPG a custom name is a beta preview feature in this release.

Support for QoS MIBs

Selected OIDs from CISCO-CLASS-BASED-QOS-MIB and CISCO-SWITCH-QOS-MIB are added for leaf and spine switches.

None.

New Hardware Features

For new hardware features, see the Cisco Nexus 9000 ACI-Mode Switches Release Notes, Release 14.2(3).

Changes in Behavior

For the changes in behavior, see the Cisco ACI Releases Changes in Behavior document.

Bug ID

Description

Exists in

CSCvt65329

The Cisco APIC GUI does not expose the 'destName' property of the vnsRedirectDest managed object.

4.2(3q) and later

CSCvu05213

Enhancement request to provide a warning prompt to users if they do a configuration export without enabling AES Encryption.

4.2(3q) and later

CSCvu18072

The Cisco APIC setup script will not accept an ID outside of the range of 1 through 12, and the Cisco APIC cannot be added to that pod. This issue will be seen in a multi-pod setup when trying add a Cisco APIC to a pod ID that is not between 1 through 12. CSCvm64933 was filed for similar issue. So there are two issues here

4.2(3q) and later

CSCvu36682

After upgrading to release 4.2(3q), the Event Manger generates a core and crashes continuously, leading to a diverged cluster.

4.2(3q) and later

CSCvu67110

This defect covers a patch for a condition similar to CSCvn15769 but not covered in the patch for it.

There are recurring crashes and core dumps on different Cisco APICs (which are VMM domain shard leaders), as well as high CPU utilization (around 200% so to 2x maxed out CPU cores) for the VMMMGr process, as well as multiple inv sync issues.

These issues are preventing the VMMMGr process from processing any operational/configuration changes that are made on the RHVs.

This can be resolved these by repeatedly restarting the vmmmgr process (the aforementioned cores are NOT caused by the process restarts). However, restarting a DME is not a recommended workaround.

4.2(3q) and later

CSCvu67494

Logging in using TACACS to 1 or multiple Cisco APICs can intermittently fail while showing fault F0023. TCPDump shows that the Cisco APIC is resetting the 3-way-handshake. Sometimes, the following error message displays:

The server is temporarily busy due to higher than usual request volume. Please try again later.

Unable to deliver the message, Resolve timeout from (type/num/svc/shard) =

4.2(3q) and later

CSCvv38458

Interface counters are cleared successfully in the CLI, but the original CRC stomped value is still observed in the GUI.

4.2(3q) and later

CSCvw37981

Selecting an external IP address that is reachable from a single L3Out, the Cisco APIC shows the following error:

"Not Supported: External address <External-IP> is reachable from GOLF interface".

4.2(3q) and later

CSCvs92682

OID "1.3.6.1.4.1.9.9.117.2.0.0.2" in v1 SNMP trap cefcPowerStatusChange by Cisco APIC is observed.

4.2(3n) and later

CSCvt37793

Packet loss is observed across the spine switches for unicast traffic.

4.2(3n) and later

CSCvt59121

Legacy mode bridge domain is intended for a specific use case that requires higher bridge domain (VLAN) numbers per switch. As of Cisco APIC release 4.2, ~2000 normal bridge domains can be deployed on the same leaf switch, while 3500 legacy mode bridge domains can be deployed on the same leaf switch. However, as a trade-off for the bridge domain (VLAN) numbers, legacy mode bridge domains lose various Cisco ACI-specific capabilities, such as contracts, pervasive gateway (bridge domain subnet). This is an enhancement to update the name of Legacy Mode for a bridge domain to reflect its functionality and purpose in the Cisco APIC GUI. With this enhancement, Legacy Mode is presented as Scaled L2 Only Mode.

4.2(3n) and later

CSCvt67097

In the Cisco APIC GUI, external EPGs under L2Out and L3Out in tenants are called "External Network Instance Profile". This is the official name for object (l2extInstP and l3extInstP). However, these are typically referred to as external EPGs. This is an enhancement to update the GUI label from "External Network Instance Profile" to "External EPG".

4.2(3n) and later

CSCvw00513

The Cisco APIC fails to start the auditd service and the following message is displayed on the console when apic boots up:

[FAILED] Failed to start Security Auditing Service.

4.2(3n) and later

CSCvo41153

We do not support a bridge domain in hardware proxy mode for flood in encapsulation. However, there is no warning or validation in the GUI.

This bug is to add validation and a warning message when the user is trying to configure flood in encapsulation.

4.2(3l) and later

CSCvs69458

Immediately after a Cisco APIC cluster upgrade, all EPG SCVMM networks are marked for deletion. Networks not attached to virtual machines are deleted. Networks that are attached to virtual machines fail to get deleted, as they are being used and the following fault gets raised on the Cisco APIC cluster for each network:

F1471EPG deployment failed due to Powershell call failed. Error Message: Cannot Delete VmNetwork

4.2(3l) and later

CSCvs90607

The L3Out wizard shows the incorrect router_id from another VRF table.

4.2(3l) and later

In a Cisco vAPIC environment in which the administrative state of Eth1/2 is down, fault F0106 is presented for Eth1/2 of the Cisco vAPIC nodes.

4.2(3l) and later

CSCvt23284

If the DVS version is 6.6 or later or the VMware vCenter version is 7.0, using basic LACP will raise errors on the VMware vCenter, as these releases of DVS and VMware vCenter no longer support LACP.

4.2(3l) and later

CSCvt34925

This bug is an enhancement to enable the configuring of SNMPv3 with SHA2 and AES256. This configuration is needed for as a security enhancement.

4.2(3l) and later

CSCvt39746

Cisco APIC interfaces e2/3 & 2/4 persist in the GUI and the MIT after disabling and enabling the port channel on the VIC.

4.2(3l) and later

The CSSM receives an extremely high number of entitlement requests from a Cisco ACI fabric, in upwards of 25,000 over a 48-hour period.

4.2(3l) and later

CSCvt44940

Fault F1298 raised and states that "Delivered,Node belongs to different POD". Actually, the node belongs to the correct POD and fault is misleading.

4.2(3l) and later

CSCvt48790

There is a stale fvIfConn entry after physically removing the ESXi host after a host is removed from the datacenter or VMware vCenter.

4.2(3l) and later

CSCvt50251

CloudSec encryption may not function when certain features are enabled, such as remote leaf switches and Cisco ACI Multi-Site intersite L3Outs.

4.2(3l) and later

CSCvt63880

A Cisco vAPIC running release 4.2(3l) goes into a sh-4.2# prompt. Runing any command returns "Admin cookie not found".

4.2(3l) and later

CSCvt68267

With DHCP in which the node is not properly decommissioned, the DHCP process released the IP address and allocated the IP address to another TEP, which caused a duplicate TEP and caused an outage.

4.2(3l) and later

CSCvt68314

Fault F0948 is raised in the fabric, where the child-most affected object is "rsBDToProfile".

4.2(3l) and later

CSCvt70316

SNMP poll/walk to the Cisco APIC does not work . The error message "unknown username" is received.

4.2(3l) and later

CSCvt70397

After decommissioning/removing a node ID from the Cisco APIC, wait for 10 minutes before re-adding the same node back into fabric. Re-adding the node too early can result in unexpected behavior, such as the node that is being decommissioned does not get wiped properly and ends up retaining the TEP address that was allocated by the Cisco APIC.

4.2(3l) and later

CSCvt72452

When using Cisco APIC release 4.2(2l), the UCSM integration icon is broken in the GUI.

4.2(3l) and later

CSCvt72773

The Authentication Type displays as "Use SSH Public/Private Files." However, Cisco APIC acts as a client to the (outside) server, and so "Private" should be the only configurable key in the "SSH Key Contents" area.

4.2(3l) and later

CSCvt72778

Editing a remote location with a private key that doesn?t have a passphrase is blocked due to form validation.

4.2(3l) and later

CSCvt96250

After creating a Global Alias Field on an EPG in a user tenant and submitting the change, the tag can be seen as successfully created on the EPG. However, operations such as renaming or deleting do not update the tag after submitting the change.

4.2(3l) and later

CSCvt98738

Code F1527 occurrs in /data/log on a Cisco APIC. After collecting the "show tech file" for the Cisco APIC, the percentage is shown as only 71%.

4.2(3l) and later

CSCvu05236

In the Cisco APIC GUI, under Fabric -> Inventory -> Pod 1 -> Leaf/Spine -> Summary -> Hardware Usage -> Memory, a memory usage value over 80% is colored red.

4.2(3l) and later

CSCvu44604

- The configuration is not pushed from the Cisco APIC to RHVM. For example, when attaching a VMM domain to an EPG, the EPG is not created as a logical network in RHVM.

- vmmmgr logs indicate that Worker Q is at 300 with Max Q of 300.

- When the Q reaches 300, it appears this is caused by the class definition 'ifc:vmmmgr:taskCompHvGetHpNicAdjQualCb' using up the entire worker Q.

- There are numerous logs indicating that the sendtoController failed and the Worker is busy.

4.2(3l) and later

CSCvu60050

Traffic drops between select EPGs involved in shared-service contract.The shared routes gets programmed with a pctag of 0 which causes traffic from the source EPG to the destination to get dropped.

4.2(3l) and later

CSCvv00341

After a switch replacement, the Cisco APIC will no longer be able to run show commands on it, such as "fabric 101 show int bri", where "101" is the Node ID of the replaced switch. The Cisco APIC will be able to send the command to the switch, but the return will be empty due to an old SSH key (the key of the old switch).

4.2(3l) and later

CSCvv15930

Visibility & Troubleshooting tool returns "Internal query error:list index out of range" followed by "Server API calls return error. Please click OK to go back to the first page.".

A VMMmgr crash maybe observed in a scaled environment with 20+ Floating L3Outs.

4.2(3j) through 4.2(3n)

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.

4.2(3j) 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]

CSCvg81020

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

4.2(3j) and later

CSCvh52046

This is an enhancement to allow for text-based banners for the Cisco APIC GUI login screen.

4.2(3j) 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.

4.2(3j) and later

CSCvj56726

The connectivity filter configuration of an access policy group is deprecated and should be removed from GUI.

4.2(3j) and later

4.2(3j) 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.

4.2(3j) 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.

4.2(3j) and later

CSCvq80820

A previously-working traffic is policy dropped after the subject is modified to have the "no stats" directive.

4.2(3j) and later

CSCvq88632

This is an enhancement request for allowing DVS MTU to be configured from a VMM domain policy and be independent of fabricMTU.

4.2(3j) and later

CSCvq95687

Currently, under Fabric > Inventory > Pod > Leaf Switch > General, the memory usage takes in consideration the MemFree field rather than the MemAvailable, which would be a more accurate representation of the usable memory in the system.

In some cases, the GUI might show that the memory utilization is around 90% while in reality it's 50%, because there is still the cached/buffered memory to take into account. This buffered/cached memory will free up a big chunk of memory in case more memory is needed.

4.2(3j) and later

CSCvq96516

There is an event manager process crash.

4.2(3j) and later

CSCvr10020

Fault alarms get generated at a higher rate with a lower threshold. There is no functional impact.

CSCvr12971

The Cisco APIC GUI produces the following error messages when opening an EPG policy:  Received Invalid Json String.  The server returned an unintelligible response.This issue might affect backup/restore functionality.

4.2(3j) and later

CSCvr19693

When configuring local SPAN in access mode using the GUI or CLI and then running the "show running-config monitor access session<session>" command, the output does not include all source span interfaces.

4.2(3j) and later

CSCvr62453

When a Cisco ACI fabric upgrade is triggered and a scheduler is created and associated to the maintenance group, the scheduler will remain associated to the maintenance group. If the version is changed in the maintenance group, it will trigger the upgrade. This enhancement is to avoid unwanted fabric upgrades. Post-upgrade, the association of the scheduler should be removed from the maintenance group after the node upgrade reaches 100%.

4.2(3j) and later

CSCvr82224

A leaf switch port flaps without raising a warning.

4.2(3j) and later

When the productSpec of a DVS is changed from Cisco Systems to Vmware Inc as a workaround for bug CSCvr86180, if the VMware vCenter is reloaded after that point, that will result in a change of the object type at the VMware vCenter (DistributedVirtualSwitch to VmwareDistributedVirtualSwitch). That has the effect of the Cisco APIC deleting the hvsLNode the next time it pulls inventory from the VMware vCenter after the VMware vCenter comes back up.

When the productSpec is switched back to Cisco Systems, a new hvsLNode is created with most of the fields left as uninitialized, which raises faults on the DVS. Lnode(DVS) gets deleted on the external VMM controller and the MTU on the DVS is different than the MTU in the policy.

TACACS+ users are unable to login to a Cisco APIC when an AV pair is in use with a dot '.' character in the domain portion. Users may be able to login with minimal permissions if the "Remote user login policy" allows it. The following example shows an AV pair that causes the issue:

shell:domains = aci.domain/admin/

Additionally, NGINX logs on the Cisco APIC show the following log line:

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.

The data in the Cisco APIC database may get deleted during an upgrade from a 3.0 or 3.1 release to a 4.0 or 4.1 release if the target release is rolled back to current running release within 2 minutes after the upgrade was started. The upgrade will continue anyway, but the Cisco APIC will lose all data in the database and a user with admin credentials cannot log in. Only the rescue-user/admin can log in.  All shards for a process show as unexpected, and the database files are removed. The last working pre-upgrade database files are copied to the purgatory directory.

4.2(3j) and later

CSCvv21442

The Cisco APIC does not allow an upgrade to be cancelled. Rolling back the target version after an upgrade is started does not stop the upgrade and may cause Cisco APIC database loss. This enhancement is filed to block a Cisco APIC target version change unless the following conditions are met:

1. All Cisco APICs are online and the cluster is fully fit.

2. The upgrade job (maintUpgJob) for all Cisco APICs are completed.

3. The Installer.py process is not running on any of the Cisco APICs.

A bridge domain subnet is explicitly marked as public. The same EPG subnet has the shared flag enabled and has an implicit private scope. The private scope should take precedence over the public scope and should not get advertised. However, the bridge domain subnet does get advertised through the L3Out.

Port-groups named "||" may be created in VMware vCenter when a vmmEpPD MO (VMM port group) is not present when the l3extRsDynPathAtt (L3Out dynamic attachment) associated with a vmmDom is deleted. L3Out dynamic attachments in VMM are created when the floating SVI feature is implemented on the L3Outs.

The port-groups named "||" that get installed in VMware vCenter can cause bug CSCvu41160 to occur, where the Cisco APIC is unable to properly parse the port group names. Bug CSCvu41160 prevents the parsing issue, while this bug aims to prevent the "||" port-group creation in the first place.

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.

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.

The admin password of ACI fabric is initially configured using the setup-script during the APIC node initialization, for example pw1. After that, customer may choose to change the admin password to a new one such as pw2. The new password pw2 is not preserved in the event of a database clean-up, which causes pw1 to be required for after a clean reload. The impact to the operation team is that they may not always document the very first Cisco APIC password, hence they will not be able to login to the Cisco APIC again due to forgetting the original admin password if the Cisco APIC had to be clean reloaded.

If a Cisco APIC is receiving a large number of DHCP requests with unique client addresses, each request will result in a unique dhcpClient managed object being created on the APIC in the requesting state. Depending on the number of unique requests, these could add up over time and cause the dhcpd process on the APIC to hit scale issues, potentially crashing, although the APIC itself will not crash and the dhcpd process will crash and recover. The dhcpd crashing issue was observed with the dhcpClient managed object count was over 4 million.

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.

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.

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.

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.

■      When the fabric node switch (spine or leaf) is out-of-fabric, the environmental sensor values, such as Current Temperature, Power Draw, and Power Consumption, might be reported as "N/A." A status might be reported as "Normal" even when the Current Temperature is "N/A."

■      First generation switches (switches without -EX, -FX, -GX, or a later suffix in the product ID) do not support Contract filters with match type "IPv4" or "IPv6." Only match type "IP" is supported. Because of this, a contract will match both IPv4 and IPv6 traffic when the match type of "IP" is used.

The following table provides compatibility information for specific hardware:

Hardware

Information

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.

N9K-C9348GC-FXP

This switch does not read SPROM information if the PSU is in a shut state. You might see an empty string in the Cisco APIC output.
