Information About EtherChannels
The following figure shows how individual links can be combined into LACP EtherChannels and channel
groups as well as function as individual links.
Figure 13: Individual Links Combined into an EtherChannel
With LACP, you can bundle up to 16 interfaces in a channel group.
When you delete the EtherChannel, Cisco NX-OS automatically deletes the associated channel group. All

member interfaces revert to their previous configuration.
You cannot disable LACP while any LACP configurations are present.

LACP ID Parameters

LACP uses the following parameters:
• LACP system priority—Each system that runs LACP has an LACP system priority value. You can
The LACP system ID is the combination of the LACP system priority value and the MAC address.
Note
• LACP port priority—Each port configured to use LACP has an LACP port priority. You can accept the
• LACP administrative key—LACP automatically configures an administrative key value equal to the
OL-16597-01
accept the default value of 32768 for this parameter, or you can configure a value between 1 and 65535.
LACP uses the system priority with the MAC address to form the system ID and also uses the system
priority during negotiation with other devices. A higher system priority value means a lower priority.
default value of 32768 for the LACP port priority, or you can configure a value between 1 and 65535.
LACP uses the port priority with the port number to form the port identifier. LACP uses the port priority
to decide which ports should be put in standby mode when there is a limitation that prevents all compatible
ports from aggregating and which ports should be put into active mode. A higher port priority value
means a lower priority for LACP. You can configure the port priority so that specified ports have a lower
priority for LACP and are most likely to be chosen as active links, rather than hot-standby links.
channel-group number on each port configured to use LACP. The administrative key defines the ability
of a port to aggregate with other ports. A port's ability to aggregate with other ports is determined by
these factors:
