■
Long Timeout – Specifies a slow timeout of 90 seconds. (This is
the default setting.)
■
Short Timeout – Specifies a fast timeout of 3 seconds.
The timeout is set in the LACP timeout bit of the Actor State field in
transmitted LACPDUs. When the partner switch receives an LACPDU set
with a short timeout from the actor switch, the partner adjusts the
transmit LACPDU interval to 1 second. When it receives an LACPDU set
with a long timeout from the actor, it adjusts the transmit LACPDU
interval to 30 seconds.
If the actor does not receive an LACPDU from its partner before the
configured timeout expires, the partner port information will be deleted
from the LACP group.
When a dynamic port-channel member leaves a port-channel, the
default timeout value will be restored on that port.
When a dynamic port-channel is torn down, the configured timeout
value will be retained. When the dynamic port-channel is constructed
again, that timeout value will be used.
Configure Aggregation Port - General
◆ Port – Port identifier. (Range: 1-28/52)
◆ LACP Status – Enables or disables LACP on a port.
Configure Aggregation Port - Actor/Partner
◆ Port – Port number. (Range: 1-28/52)
◆ Admin Key – The LACP administration key must be set to the same
value for ports that belong to the same LAG. (Range: 0-65535;
Default – Actor: 1, Partner: 0)
By default, the actor’s operational key is determined by port's link
speed (1000f - 4, 100f - 3, 10f - 2), and copied to the admin key.
◆ System Priority – LACP system priority is used to determine link
aggregation group (LAG) membership, and to identify this device to
other switches during LAG negotiations. (Range: 0-65535;
Default: 32768)
System priority is combined with the switch’s MAC address to form the
LAG identifier. This identifier is used to indicate a specific LAG during
LACP negotiations with other systems.
◆ Port Priority – If a link goes down, LACP port priority is used to select
a backup link. (Range: 0-65535; Default: 32768)
■
Setting a lower value indicates a higher effective priority.
■
If an active port link goes down, the backup port with the highest
priority is selected to replace the downed link. However, if two or
