Licensing Requirements for Port Channeling Chapter 6 Configuring Port Channels Send document comments to [email protected] Beginning with Cisco NX-OS Release 5.1, the port channel goes down if the operational ports fall below the configured minlink number. Note See the Cisco Nexus 7000 Series NX-OS High Availability and Redundancy Guide, Release 5.x, for complete information on high-availability features. Licensing Requirements for Port Channeling The following table shows the licensing requirements for this feature: Product Cisco NX-OS License Requirement Port channeling requires no license. Any feature not included in a license package is bundled with the Cisco NX-OS system images and is provided at no extra charge to you. For a complete explanation of the NX-OS licensing scheme, see the Cisco NX-OS Licensing Guide. However, using VDCs requires an Advanced Services license. Prerequisites for Port Channeling Port channeling has the following prerequisites: • You must be logged onto the device. • If necessary, install the Advanced Services license and enter the desired VDC. • All ports in the channel group must be in the same VDC. • All ports for a single port channel must be either Layer 2 or Layer 3 ports. • All ports for a single port channel must meet the compatibility requirements. See the "Compatibility Requirements" section on page 6-5 for more information on the compatibility requirements. • You must configure load balancing from the default VDC. Guidelines and Limitations Port channeling has the following configuration guidelines and limitations: • You must enable LACP before you can use that feature. • You can configure multiple port channels on a device. • Do not put shared and dedicated ports into the same port channel. (See Chapter 2, "Configuring Basic Interface Parameters," for information on shared and dedicated ports.) • For Layer 2 port channels, ports with different STP port path costs can form a port channel if they are compatibly configured with each other. See "Compatibility Requirements" section on page 6-5 for more information on the compatibility requirements. 6-14 Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 5.x OL-23435-03
