Lists data for only the LACP-configured ports.
Example:
Ports A1 and A2 have been previously configured for a static LACP trunk. (For more on the Active parameter,
see table "

Dynamic LACP Standby Links
Dynamic LACP trunking enables you to configure standby links for a trunk by including more than eight ports in a
dynamic LACP trunk configuration. When eight ports (trunk links) are up, the remaining link(s) will be held in
standby status. If a trunked link that is “Up” fails, it will be replaced by a standby link, which maintains your
intended bandwidth for the trunk. (Refer to also the “Standby” entry under “Port Status” in "Table 4-5. LACP Port
Status Data".) In the next Example:, ports A1 through A9 have been configured for the same LACP trunk. Notice
that one of the links shows Standby status, while the remaining eight links are “Up”.
