lacp timeout
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 switch to indicate the rate at which it expects to receive
LACPDUs from its neighbor.
If the timeout is set to long, then the switch 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 switch 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 switch 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 switch has set the short
timeout. If the ‘Timeout’ field is set to 0, then the switch has set the long timeout.
Setting the short timeout enables the switch to be more responsive to communication
failure on a link, and does not add too much processing overhead to the switch (1 packet
per second).
Examples The following commands set the LACP long timeout period for 30 seconds on
port1.0.2
.
Parameter Description
timeout Number of seconds before invalidating a received LACP data unit
(DU).
short LACP short timeout. The short timeout value is 1 second.
long LACP long timeout. The long timeout value is 30 seconds.
Note It is not possible to configure the rate that the switch sends LACPDUs; the
switch must send at the rate which the neighbor indicates it expects to receive
LACPDUs.
