This field... Displays...
Agg Indicates the link aggregation state of the port. The state can be one of the following:
• Agg - Link aggregation is enabled on the port.
• No - Link aggregation is disabled on the port.
Syn Indicates the synchronization state of the port. The state can be one of the following:
• No - The port is out of sync with the remote port. The port does not understand the
status of the LACPDU process and is not prepared to enter a LAG link.
• Syn - The port is in sync with the remote port. The port understands the status of the
LACPDU message exchange process, and therefore knows the LAG group to which it
belongs, the link aggregation state of the remote port, and so on.
Dis Indicates the collection state of the port, which determines whether the port is ready to
send traffic over the LAG link:
• Col - The port is ready to send traffic over the LAG link.
• No - The port is not ready to send traffic over the LAG link.
Col Indicates the distribution state of the port, which determines whether the port is ready to
receive traffic over the LAG link.
• Dis - The port is ready to receive traffic over the LAG link.
• No - The port is not ready to receive traffic over the LAG link.
Def Indicates whether the port is using default link aggregation values. The port uses default
values if it has not received link aggregation information through LACP from the port at
the remote end of the link. This field can have one of the following values:
• Def - The port has not received link aggregation values from the port at the other end
of the link and is therefore using its default link aggregation LACP settings.
• No - The port has received link aggregation information from the port at the other end
of the link and is using the settings negotiated with that port.
Exp Indicates whether the negotiated link aggregation settings have expired. The settings
expire if the port does not receive an LACPDU message from the port at the other end of
the link before the message timer expires. This field can have one of the following values:
• Exp - The link aggregation settings this port negotiated with the port at the other end of
the link have expired. The port is now using its default link aggregation settings.
• No - The link aggregation values that this port negotiated with the port at the other end
of the link have not expired. The port is still using the negotiated settings.
Ope • Ope (operational) - The port is operating normally.
• Blo (blocked) - The port is blocked because the adjacent port is not configured with
link aggregation or because it is not able to join a LAG group. An LACP port is blocked
until it becomes part of a LAG. Also, an LACP is blocked if its state becomes "default".
To unblock the port and bring it to an operational state, enable link aggregation on the
adjacent port and ensure that the ports have the same key.
• Frc (force-up)- The port is in "force-up" mode. If you have configured the force-up
ethernet command on the member port of a dynamic LAG, the port goes into "force-
up" mode and is logically operational when the dynamic LAG is not operating.
