port
Syntax port port-id [port-id ...up to 4 total] [priority priority] [subgroup sub-group-id]
no port port-id [port-id ...up to 4 total]
Context config>lag lag-id
Description
This command adds ports to a Link Aggregation Group (LAG).
The port configuration of the first port added to the LAG is used as a basis to compare to subsequently added
ports. If a discrepancy is found with a newly added port, that port will be not added to the LAG.
Up to 4 (space separated) ports can be added or removed from the LAG link assuming the maximum of 4
ports is not exceeded.
All ports, when added to a LAG, must share the same characteristics (speed, duplex, etc.). An error message
will be displayed when adding ports that do not share the same characteristics. Hold-timers down must be 0.
Ports that are part of a LAG must be configured with autonegotiate limited or disabled.
The no form of this command removes ports from the LAG.
Default
No ports are defined as members of a LAG.
Parameters
port-id — The port ID configured or displayed in the slot/mda/port format.
priority priority — Port priority used by LACP. The port priority is also used to determine the primary port.
The port with the lowest priority is the primary port. In the event of a tie, the smallest port ID becomes
the primary port.
Values
subgroup sub-group-id — ValuesThis parameter identifies a LAG subgroup. When using subgroups in a

Context config>lag lag-id
Description
This command configures the behavior for the Link Aggregation Group (LAG) if the number of operational
links is equal to or below a threshold level.
Note: The 7210 SAS-M and 7210 SAS-T access-uplink mode supports only 'down' value for the action
parameter. Network mode (7210 SAS-M, 7210 SAS-T, 7210 SAS-X, 7210 SAS-R6 and 7210 SAS-Mxp)
supports both 'dynamic-cost' and 'down' values for action parameter.

LAG, they should only be configured on one side of the LAG, not both. Only having one
side perform the active/standby selection will guarantee a consistent selection and fast
convergence. The active/standby selection will be signalled through LACP to the other
side. The hold time should be configured when using subgroups to prevent the LAG going
down when switching between active and standby links in case no links are usable for a
short time, especially in case a subgroup consists of one member.1 — 2 identifies a LAG
subgroup.
