SecureStack C2 Configuration Guide 5-35
• 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.
• 802.1x authentication is enabled using the set eapol command ( page 18 ‐ 17 ) and ports that
would otherwise aggregate are not 802.1X authorized.
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.
Commands
show lacp
Use this command to display information about one or more aggregator ports.
Syntax
show lacp [ port-string ]
Note: To aggregate, underlying physical ports must be running in full duplex mode and must be of
the same operating speed.
