Configuring Port Channels
This chapter describes how to configure port channels and to apply and configure the Link Aggregation
Control Protocol (LACP) for more efficient use of port channels in the Cisco NX-OS devices.
Beginning with Cisco Release NX-OS 5.1(1), you can use any of the F1 series modules or M1 series
modules for the port channel, but you cannot combine member ports on an F1 module with ports on an
M1 module in a single port channel. On a single switch, the port-channel compatibility parameters must
be the same among all the port-channel members on the physical switch.

Information About Port Channels

A port channel is an aggregation of multiple physical interfaces that creates a logical interface. You can
bundle up to 8 individual active links into a port channel to provide increased bandwidth and
redundancy. Port channeling also load balances traffic on the M series module and across these physical
interfaces. The port channel stays operational as long as at least one physical interface within the port
channel is operational.
Beginning with Cisco NX-OS Release 5.1, you can bundle up to 16 active links into a port channel on
Note
the F Series module.
