LACP
TIMEOUT
lacp timeout
Overview
Use this command to set the short or long timeout on a port. Ports will time out of
the aggregation if three consecutive updates are lost.
Syntax
lacp timeout {short|long}
Default
The default is
long
timeout (30 seconds).
Mode
Interface Configuration
Usage
This command enables the device to indicate the rate at which it expects to receive
LACPDUs from its neighbor.
If the timeout is set to
long
, then the device expects to receive an update every
30
seconds, and this will time a port out of the aggregation if no updates are seen for
90 seconds (i.e. 3 consecutive updates are lost).
If the timeout is set to
short
, then the device expects to receive an update every
second, and this will time a port a port out of the aggregation if no updates are
seen for 3 seconds (i.e. 3 consecutive updates are lost).
The device indicates its preference by means of the Timeout field in the Actor
section of its LACPDUs. If the Timeout field is set to 1, then the device has set the
short
timeout. If the Timeout field is set to 0, then the device has set the
long
timeout.
Setting the
short
timeout enables the device to be more responsive to
communication failure on a link, and does not add too much processing overhead
to the device (1 packet per second).
NOTE
:
It is not possible to configure the rate that the device sends LACPDUs; the device
must send at the rate which the neighbor indicates it expects to receive LACPDUs.
Examples

port1.0.2
.
