3.13.2.29 LAG Commands
lag
Syntax [no] lag lag-id
Context config
Description This command enables the context in which Link Aggregation Group (LAG) attributes are
defined.
A LAG groups two or more Ethernet links (ports) into one logical link. The aggregation of
multiple physical links adds redundancy and improves resiliency between two network
devices, and allows for load sharing.
On access ports, a LAG can have a maximum of two links and can support active/standby
operation. If an active link in a LAG fails, traffic gets redistributed to the standby link.
On network ports, a LAG can have a maximum of eight links (depending on the platform or
adapter card/module and the Ethernet port type) and can support active/active and
active/standby operation. In active/active mode, the links are used for load sharing.
The no form of this command deletes the LAG from the configuration. A LAG can only be
deleted while it is administratively shut down. Any dependencies, such as IP interface
configurations, must be removed from the LAG before it can be shut down.
