There is no available aggregator for two or more ports with the same LAG ID. This can
happen if there are simply no available aggregators, or if none of the aggregators have a
matching admin key and system priority.

The LACP implementation on the SecureStack C2 device will allow up to eightphysical ports into
a LAG. The device with the lowest LAG ID determines which underlying physical ports are
allowed into a LAG based on the ports' LAG port priority. Ports with the lowest LAG port priority
values are allowed into the LAG and all other speed groupings go into a standby state.
When an existing dynamically created LAG is reduced to one port, the SecureStack C2 removes
the LAG from its VLAN and adds the remaining underlying port to the VLAN. For this reason,
you should ensure that the LAG and all the ports in the LAG are assigned to the egress list of the
desired VLAN. Otherwise, when the LAG is removed, the remaining port may be assigned to the
wrong VLAN. The other option is to enable the singleportlag feature as described in "set lacp
singleportlag" on page 5‐40.

the same operating speed.
