Lacp Timeout - Allied Telesis SwitchBlade x908 Series Software Reference Manual

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. The default is the long timeout of 30
seconds.
Syntax
lacp timeout {short|long}
Parameter
timeout
short
long
Interface mode
Mode
The default is long timeout.
Default
This command enables the switch to indicate the rate at which it expects to receive LACPDUs
Usage
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).
Note:
The following commands set the LACP long timeout period for 30 seconds on port 1.0.2.
Example
awplus(config-if)#
The following commands set the LACP short timeout for 1 second on port 1.0.2.
awplus(config-if)#
C613-50007-01 REV B
Description
Number of seconds before invalidating a received LACP data unit (DU).
LACP short timeout. The short timeout value is 1 second.
LACP long timeout. The long timeout value is 30 seconds.
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.
