Description
This command configures the configuration module on the master controller.
Syntax
Usage Guidelines
By default, Mobility Manager configuration updates on the controller are disabled to prevent any alterations to
the controller configuration. You need to explicitly enable Mobility Manager configuration updates for the
controller to accept configuration changes from Mobility Manager. When Mobility Manager configuration
updates are enabled, global configuration changes can only be done from Mobility Manager and are not available
on the master controller. You can use the cfgm mms config disable command if the controller loses connectivity
to the Mobility Manager and you must enter a configuration change on the master controller.
Example
The following command allows configuration updates from the Mobility Manager:
(host)(config) #cfgm mms config enable
Command History
This command was introduced in ArubaOS 3.1.
Parameter Description Range Default
set config-chunk Maximum packet size, in Kilobytes, that is sent every
second to the local controller whenever the master
controller sends a configuration to the local. If the
connection between the master and local is slow or
uneven, you can lower the size to reduce the amount of
data that needs to be retransmitted. If the connection is
very fast and stable, you can increase the size to make
the transmission more efficient.
1-100 10 Kbytes
set heartbeat Interval, in seconds, at which heartbeats are sent. You
can increase the interval to reduce traffic load.
10-300 10 seconds
set maximum-updates Maximum number of local controllers that can be
updated at the same time with configuration changes.
You can decrease this value if you have a busy network.
You can increase this value to improve configuration
synchronization.
2-25 5
snapshot-timer Interval, in minutes, that the local controller waits for a
configuration download from the master upon bootup or
startup before loading the last snapshot configuration.
5-60 5 minutes
sync-command-blocks To configure the number of command-list blocks. Each
block contains a list of global configuration commands
for each write-mem operation.
1-3 3
sync-type complete To revert to the old master/local configuration
synchronization behavior in case there are issues
encountered using the new behavior.
——
sync-type snapshot To revert to configuration snapshot behavior, in which
only the incremental updates are sent to the local.
