Displaying and determining the status of aggregate links
Tio Indicates the timeout value of the port. The timeout value can be one of the following:
• L – Long. The trunk group has already been formed and the port is therefore using a longer
message timeout for the LACPDU messages exchanged with the remote port. Typically,
these messages are used as confirmation of the health of the aggregate link.
• S – Short. The port has just started the LACPDU message exchange process with the port
at the other end of the link. The S timeout value also can mean that the link aggregation
information received from the remote port has expired and the ports are starting a new
information exchange.
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 trunk 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 trunk group to which it
belongs, the link aggregation state of the remote port, and so on.
Col Indicates the collection state of the port, which determines whether the port is ready to send
traffic over the trunk link:
• Col – The port is ready to send traffic over the trunk link.
• No – The port is not ready to send traffic over the trunk link.
Dis Indicates the distribution state of the port, which determines whether the port is ready to receive
traffic over the trunk link:
• Dis – The port is ready to receive traffic over the trunk link.
• No – The port is not ready to receive traffic over the trunk 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, so the port is still using the negotiated settings.
Ope
• Ope (operational) - The port is operating normally.
• Ina (inactive) - The port is inactive because the port on the other side of the link is down or
has stopped transmitting LACP packets.
• 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 trunk group. 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.
