Each S- K- or 7100-Series module designates a specific number of virtual link aggregation ports which the Link Aggregation Control Protocol (LACP) can use to dynamically group multiple physical ports into one logical link. Once underlying physical ports (such as ge.x.x) are associated with an aggregator port, the resulting aggregation is represented as one Link Aggregation Group (LAG) with a lag.x.x port designation.
Refer to the Link Aggregation Control Protocol (LACP) Configuration for more information.
The 7100-Series only supports LAGs as mirror destinations. A LAG is not supported as a mirror source.
On the S- and K-Series, when used as a source port in a mirror, LAG ports act identically to a single physical port. Either dynamic or static LAGs can be used as source ports. When used as a destination port in a mirror, the mirror is configured as an IDS mirror as described in the next section.
