■      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 ACI leaf switches

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

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

■      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

—     2.0(9c) 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 using an AVS VMM domain with both VLAN and 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 2.1(1) at the following URL:

■      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:

https://www.cisco.com/c/en/us/support/servers-unified-computing/ucs-director/products-device-support-tables-list.html

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 port channel (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:

—    Generation 1—Cisco Nexus N9000K switches without “EX” on the end of the switch name; for example, N9K-9312TX

—    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.

■      Cisco ACI does not support a class E address as a VTEP address.

■      In a multipod fabric, if a spine in POD1 uses the infra tenant L3extOut-1, the TORs of the other pods (POD2, POD3) cannot use the same infra L3extOut (L3extOut-1) for Layer 3 EVPN control plane connectivity. Each POD must use its own spine switch and infra L3extOut.

■      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 Software Features

■      New Hardware Features

■      Changes in Behavior

New Software Features

Table 2 lists the new software features in this release:

Table 2 New Software Features, Guidelines, and Restrictions

Feature

Description

Guidelines and Restrictions

64-Way ECMP

64-way ECMP can be enabled on external links for the following switches:

·       N9K-X9736C-EX

·       N9K-X9732C-EX

·       N9K-C9504-FM-E

·       N9K-C9508-FM-E

None.

ACI Security Microsegmentation Closed Loop Feedback Solution with FirePOWER NGIPS for AVS, vDS, and Bare-Metal Workloads

The FirePOWER Next-Generation Intrusion Prevention System (NGIPS) can be used for vulnerability detection, which then performs automatic microsegmentation of rogue endpoints in ACI fabric for Cisco Application Virtual Switch (AVS), VMware vSphere Distributed Switch (VDS), and Bare-Metal workloads.

In the case of dynamic EPG deployment of ACI with DVS, this feature will only work on 9300-EX switches. This is because microsegmentation is only supported for DVS on 9300-EX switches. The host and virtual machine, which are the source of an external attack, must be connected to a 9300-EX switch.

Advertising EVPN Type 2 Host Routes

For optimal traffic forwarding in an EVPN topology, you can enable fabric spines to advertise host routes using EVPN type 2 (MAC-IP) routes to the DCIG along with public bridge domain subnets in the form of BGP EVPN type 5 (IP prefix) routes.

None.

Contract Permit Logging Support for Multipod

The contract permit logging feature is now supported with multipod.

This feature is supported only on 9300-EX switches.

Copy Services Support for Multipod

The copy services feature is now supported with multipod.

This feature is supported only on 9300-EX switches.

Explicit Prefix List Support for Route Maps/Profile Enhancement

In the APIC, for public bridge domain subnets and external transit networks, inbound and outbound route controls are provided through an explicit prefix list. An explicit prefix list presents an alternate method of usage and is defined through a new match type that is called the “match route destination” (rtctrlMatchRtDest). The explicit prefix list is used for advertising bridge domain subnets through the bridge domain to the Layer 3 Outside relation and specifying a subnet in the l3extInstP with export/import route control for advertising transit and external networks.

For more information, see the Cisco APIC Layer 3 Networking Configuration Guide.

None.

Federal Information Processing Standards Support

The APIC can be configured the to use the Federal Information Processing Standards (FIPS) for cryptography.

None.

Global Toggling Between In-band Management and Out-of-band Management

A global toggle is implemented between in-band management connectivity and out-of-band management connectivity as the default connectivity mode between the APIC server and management devices external to the ACI fabric.

None.

IGMP Snooping

The APIC provides support for the following IGMP-related features:

·       Static port group implementation—IGMP static port grouping enables you to pre-provision ports that are already statically-assigned to an application EPG as the switch ports to receive and process IGMP multicast traffic. This pre-provisioning prevents the flooding of all ports on a bridge domain with Layer 2 multicast traffic.

·       Access group configuration for application EPGs—An access-group is used to control what streams can be joined behind a given port.

For more information, see the Cisco APIC Layer 3 Networking Configuration Guide.

Static group membership can be pre-provisioned only on static ports assigned to an application EPG.

For access groups, only route-map-based access groups are allowed.

IP Address-Based Microsegmented Endpoint Groups Configured as Shared Services

IP address-based microsegmented endpoint groups can be configured as shared services, accessible by devices located on VRFs other than the one on which the endpoint group is located.

This configuration can only be applied to unicast IP addresses with a 32-bit netmask. For example: 125.125.125.111/32.

IP Aging

This feature tracks and ages unused IPs on an endpoint. For more information, see the Cisco APIC Layer 3 Networking Configuration Guide.

None.

Layer 3 Multicast Support for Multipod

Layer 3 multicast is now supported with multipod. For more information, see the Cisco APIC Layer 3 Networking Configuration Guide.

None.

Network-Based Microsegmented Endpoint Group Support on Bare-Metal Environments

Configuration of microsegmented endpoint groups based on MAC address or IP address attributes is now supported on physical as well as virtual environments.

None.

Policy-Based Redirect Support for Multipod

The policy-based redirect feature is now supported with multipod.

None.

Port Security Support

The port security feature is now supported on the 9300-EX switches.

None.

Translating QoS Ingress Markings to Egress Markings

The APIC enables translating the 802.1P Class of Service (CoS) field based on the ingress DSCP value. This functionality enables the ACI fabric to classify the traffic for devices that classify the traffic based only on the CoS value. The functionality also allows you to derive the dot1P CoS field based on the ingress dot1P value.

Trunk Port Group

Trunk port groups can be used to aggregate the traffic of endpoint groups. For more information, see the Cisco ACI Virtualization Guide, Release 2.1(1) and Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, Release 2.1(1).

Supported only under a VMware domain.

User-Identity Microsegmentation with FirePOWER and ACI for Secure VDI

You can now have a secure VDI deployment based on user-identity microsegmentation using FirePOWER and Active Directory integration. The solution works by applying an NAC policy to provide secure access to endpoints in a server endpoint group within the ACI fabric.

None.

Windows Azure Pack Enhancements

In the Windows Azure Pack tenant portal GUI, you can now add and provide a new context name while creating a bridge domain.

In the Windows Azure Pack tenant portal GUI for a virtual private cloud (VPC) plan, the tenant can now delete a context.

For more information, see the Cisco ACI Virtualization Guide, Release 2.1(1).

None.

New Hardware Features

For new hardware features, see the Cisco Nexus 9000 ACI-Mode Switches Release Notes, Release 12.1(1) at the following location:

https://www.cisco.com/c/en/us/support/switches/nexus-9000-series-switches/products-release-notes-list.html

CSCvp64280

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.

■    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.
