For more information, see the Cisco APIC Layer 2 Networking Configuration Guide.

For the guidelines and restrictions of this feature, see the Cisco APIC Layer 2 Networking Configuration Guide.

Breakout Ports

With this release, you can break out a 40 Gigabit Ethernet (GE) leaf switch port to be connected to 4-10GE-capable (downlink) devices that are connected with Cisco 40-Gigabit to 4X10-Gigabit breakout cables.

For more information, see the Cisco APIC Layer 2 Networking Configuration Guide.

This feature is supported only on the access facing ports of the N9K-C9332PQ switch.

Cisco ACI App Center

The Cisco ACI App Center allows you to enable the capabilities of the Cisco APIC fully by writing applications that are running on the controller. Using the Cisco ACI App Center, customers, developers, and partners can build applications to simplify, enhance, and visualize their use cases. These applications are hosted and shared at the Cisco ACI App Center and installed in the Cisco APIC.

For more information, see the Cisco ACI App Center Developer Guide.

None.

HSRP Support

HSRP is a first-hop redundancy protocol (FHRP) that allows a transparent failover of the first-hop IP router. HSRP provides first-hop routing redundancy for IP hosts on Ethernet networks configured with a default router IP address.  You use HSRP in a group of routers for selecting an active router and a standby router. In a group of routers, the active router is the router that routes packets, and the standby router is the router that takes over when the active router fails or when preset conditions are met.

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

For the guidelines and restrictions of this feature, see the Cisco APIC Layer 3 Networking Configuration Guide.

Cisco APIC High Availability Standby

The high availability functionality for an APIC cluster enables you to operate the APICs in a cluster in an active/standby mode. In an APIC cluster, the designated active APICs share the load and the designated standby APICs can act as an replacement for any of the APICs in an active cluster.

For more information, see the Cisco APIC Management, Installation, Upgrade, and Downgrade Guide.

An admin user can set up the high availability functionality when the APIC is launched for the first time. We recommend that you have at least 3 active APICs in a cluster, and one or more standby APICs. An admin user must initiate the switch over to replace an active APIC with a standby APIC.

Contract Preferred Groups

Support is added for contract preferred groups that enable greater control of communication between EPGs in a VRF. If most of the EPGs in the VRF should have open communication, but a few should only have limited communication with the other EPGs, you can configure a combination of a contract preferred group and contracts with filters to control communication precisely.

None.

ICMP and UDP Flow Logging for Distributed Firewall

Beginning with Cisco AVS release 5.2(1)SV3(2.8), Cisco AVS monitors ICMP and UDP flows as well as TCP flows by default when you enable Distributed Firewall. However, Cisco AVS does not deny ICMP and UDP flows as it does TCP flows.

For more information, see the Distributed Firewall section of the Cisco AVS chapter of the Cisco ACI Virtualization Guide, Release 2.2(1) and the Cisco AVS Troubleshooting Guide.

None.

NetFlow

The NetFlow technology provides the metering base for a key set of applications, including network traffic accounting, usage-based network billing, network planning, as well as denial of services monitoring, network monitoring, outbound marketing, and data mining for both service providers and enterprise customers. Cisco provides a set of NetFlow applications to collect NetFlow export data, perform data volume reduction, perform post-processing, and provide end-user applications with easy access to NetFlow data. If you have enabled NetFlow monitoring of the traffic flowing through your datacenters, this feature enables you to perform the same level of monitoring of the traffic flowing through the Cisco ACI fabric.

For more information, see the Cisco ACI Virtualization Guide, Release 2.2(1).

This feature is supported only on EX switches.

For additional limitations, see the Cisco APIC and NetFlow document.

RBAC Change Remote User Role

Remote users can now request a role change.

For more information see, Cisco ACI AAA RBAC Rules and Privileges document.

None.

Support for FCoE Configuration over FEX Ports

You can now configure FCoE over FEX ports.

For more information, see the Cisco APIC Basic Configuration Guide, Release 2.2(1).

None.

2.2(1n) and later

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.
