Introduction

The Cisco Application Centric Infrastructure (ACI) is an architecture that allows the application to define the networking requirements in a programmatic way. This architecture simplifies, optimizes, and accelerates the entire application deployment life cycle.

The Cisco Application Centric Infrastructure Fundamentals guide provides complete details about the ACI, including its two major components:

• Cisco Application Policy Infrastructure Controller (APIC)
• ACI Fabric, including Cisco Nexus 9000 spine and leaf switches

The Cisco Application Centric Infrastructure Fundamentals guide also includes a glossary of terms that are used in the ACI.

Key features of the ACI include the following:

• Simplified automation with an application-driven policy model
• Common platform for managing physical, virtual, and cloud-based environments
• Centralized visibility with real-time, application health monitoring
• Operational simplicity, with common policy, management, and operation models across application, network, and security resources
• Open software flexibility for DevOps teams and ecosystem partner integration
• Scalable performance and secure multi-tenancy

Cisco Application Policy Infrastructure Controller

The Cisco Application Policy Infrastructure Controller (APIC) enables applications to directly connect with a secure, shared, high-performance resource pool that includes networking and Layer 4 through 7 services.

The key features of the APIC include the following:

• Application centric network policies
• Data model-based declarative provisioning
• Application, topology monitoring, and troubleshooting
• Third-party integration (Layer 4 through 7 services, vCenter, vShield)
• Image management (spine and leaf)
• Cisco ACI inventory and configuration
• Implementation on a distributed framework across a cluster of appliances
• Health Scores for key Managed Objects (tenants, application profiles, switches, etc)
• Fault, event and performance management
• Cisco Application Virtual Switch (AVS) that can be used as a virtual Leaf for the Cisco APIC

ACI Fabric and Switches

A clustered replicated APIC appliance manages the ACI fabric. Cisco Nexus 9000 Series switches can run with the ACI-compatible software to run in the leaf/spine fabric mode. These switches form a “fat-tree” network by connecting each leaf node to each spine node; all other devices connect to the leaf nodes.

Figure 1shows the ACI Fabric with Cisco Nexus 9508, Cisco Nexus 9300 Series leaf switches, and the APIC.

Software Upgrade Recommendation

It is recommended that you upgrade your software to Cisco APIC Release 1.0(1k) because the release includes a resolution for the vulnerability of bash that is identified by the Common Vulnerability and Exposures (CVE) IDs: CVE-2014-6271 and CVE-2014-7169.

Installation Notes

For installation instructions, see the Cisco ACI Fabric Hardware Installation Guide .

For instructions on how to access the APIC for the first time, see the Cisco APIC Getting Started Guide.

Compatibility Information

Cisco APIC Release 1.0(1e) supports the following software:

• Cisco NX-OS Release 11.0(1b)
• Cisco AVS, Release 4.2(1)SV2(2.3)
• Cisco ASA 5585, Release 8.4 and later
• Cisco ASAv (virtual), Release 9.2.1
• Cisco UCS Manager software Release 2.2(1c) or later is required for the Cisco UCS Fabric Interconnect and other components, including the BIOS, CIMC, and the adapter
• F5, Big IP, LTM Physical, LTM Virtual, Release 11.4.1
• Citrix Netscaler, MPX, SDX, VPX, Release 10.1 and later
• Citrix Netscaler 1000v, ESX 5.0 and later
• VMware vCenter 5.1 and 5.5 and vShield 5.1 and 5.5

Usage Guidelines

This section list usage guidelines for the APIC software.

• The APIC GUI supports the following browsers:

– Chrome version 35 and higher on Mac and Windows

– Firefox version 26 on Mac, Linux, and Windows

– Internet Explorer version 11 or higher

– Safari 7.0.3

---

Caution A known issue exists with the Safari browser and unsigned certificates. Read the information presented here before accepting an unsigned certificate for use with WebSockets.

When you access the HTTPS site, the following message appears:
“Safari can’t verify the identity of the website APIC. The certificate for this website is invalid. You might be connecting to a website that is pretending to be an APIC, which could put your confidential information at risk. Would you like to connect to the website anyway?”

To ensure that WebSockets can connect, you must do the following:

Click Show Certificate.
Select Alway Trust in the three drop-down lists that appear.

If you do not follow these steps, WebSockets will not be able to connect.

---

• 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 inband and out-of-band networks.
• The APIC does not provide an IPAM solution, so ensure that IP addresses are unique within a private network/ context.
• Press the Escape key twice (<Esc> <Esc>) to display APIC CLI command options.
• For the following services, use a DNS-based host name with out-of-band management connectivity. IP addresses can be used with both inband and out-of-band management connectivity.

– Syslog server

– Call Home SMPT server

– Tech support export server

– Configuration export server

– Statistics export server

• Inband management connectivity to the spine switches is possible from any host that is connected to the leaf switches of the Fabric, and leaf switches can be managed from any host that has IP connectivity to the fabric.
• The current list of protocols that are allowed (and cannot be blocked through contracts) include the following. Some of the protocols have SrcPort/DstPort distinction.

– UDP DestPort 161: SNMP. These cannot be blocked through contracts. Creating an SNMP ClientGroup with a list of Client-IP Addresses restricts SNMP access to only those configured Client-IP Addresses. If no Client-IP address is configured, SNMP packets are allowed from anywhere.

– TCP SrcPort 179: BGP

– TCP DstPort 179: BGP

– OSPF

– UDP DstPort 67: BOOTP/DHCP

– UDP DstPort 68: BOOTP/DHCP

– IGMP

– PIM

– UDP SrcPort 53: DNS replies

– TCP SrcPort 25: SMTP replies

– TCP DstPort 443: HTTPS

– UDP SrcPort 123: NTP

– UDP DstPort 123: NTP
