Listing Static LACP and Dynamic LACP Trunk Data.
Syntax: show lacp
Lists data for only the LACP-configured ports..
In the following example, ports A1 and A2 have been previously configured
for a static LACP trunk. (For more on the “Active” parameter, see table 12-5
on page 12-20.)

(For a description of each of the above-listed data types, refer to table 12-5,
“LACP Port Status Data” on page 12-20.)
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 12-5. LACP Port Status Data" on page 12-20.) 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”.
