This command creates the context for configuring Link Aggregation Group (LAG) attributes.
A LAG can be used to group up to 4 ports into one logical link. The aggregation of multiple physical links
allows for load sharing and offers seamless redundancy. If one of the links fails, traffic will be redistributed
over the remaining links. Up to 4 links can be supported in a single LAG, up to 12 LAGs can be configured
on a node.
NOTE: All ports in a LAG group must have autonegotiation set to Limited or Disabled.
There are three possible settings for autonegotiation:
“on” or enabled with full port capabilities advertised
off” or disabled where there is no autonegotiation advertisements
“limited” where a single speed/duplex is advertised.
When autonegotiation is enabled on a port, the link attempts to automatically negotiate the link speed and
duplex parameters. If autonegotiation is enabled, the configured duplex and speed parameters are ignored.
When autonegotiation is disabled on a port, the port does not attempt to autonegotiate and will only operate
at the speed and duplex settings configured for the port. Note that disabling autonegotiation on gigabit ports
is not allowed as the IEEE 802.3 specification for gigabit Ethernet requires autonegotiation be enabled for
far end fault indication.
If the autonegotiate limited keyword option is specified the port will autonegotate but will only advertise a
specific speed and duplex. The speed and duplex advertised are the speed and duplex settings configured
for the port. One use for limited mode is for multispeed gigabit ports to force gigabit operation while
keeping autonegotiation is enabled for compliance with IEEE 801.3.
The system requires that autonegotiation be disabled or limited for ports in a LAG to guarantee a specific
port speed.
The no form of this command deletes the LAG from the configuration. Deleting a LAG can only be
performed while the LAG is administratively shut down. Any dependencies such as IP-Interfaces
configurations must be removed from the configuration before issuing the no lag command.
Default No LAGs are defined.
Parameters lag-id — The LAG identifier, expressed as a decimal integer.
