NOTE: Use the show trunk command to determine the status of LACP.
Clearing the Negotiated Link Aggregations
When a group of ports negotiates a trunk group configuration, the software stores the negotiated configuration in a
table. You can clear the negotiated link aggregation configurations from the software. When you clear the
information, the software does not remove link aggregation parameter settings you have configured. Only the
configuration information negotiated using LACP is removed.
NOTE: The software automatically updates the link aggregation configuration based on LACPDU messages.
However, clearing the link aggregation information can be useful if you are troubleshooting a configuration.
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.
