Alcatel-Lucent AOS-W 6.5.3.x - Page 649

Command Description
cfgm set sync-type <complete>
The master sends the full configuration file to the
local.
cfgm set sync-type <snapshot>
The master sends only the incremental
configuration to the local.
NOTE: This configuration is enabled by default
cfgm set sync-command-block <number>
Configures the number of command-list blocks.
Each block contains a list of global configuration
commands for each write-mem operation. The
number is 3 by default.
show master-configpending
Displays a list of global commands that are not
saved but sent to the local.
clear master-local-session <A.B.C.D>
Manually pushes the full configuration to the local.

Configuring Master-Local Switch Redundancy
This section outlines the concepts behind a redundancy solution where a master can act as a backup for one or
more local switches, and shows how to configure the Alcatel-Lucent switches for such a redundant solution. In
this solution, the local switches act as the switch for the APs. When any one of the local switches becomes
unavailable, the master takes over the APs controlled by that local switch for the time that the local switch
remains unavailable. It is configured such that when the local switch comes back again, it can take control over
the APs once more.
This type of redundant solution is illustrated by the following topology diagram:
This solution requires that the master switch have Layer-2 connectivity to all local switches.
Figure 83 Redundant Topology: Master-Local Redundancy
In the network in Figure 83, the master switch is connected to the local switches on VLANs 1 through n using a
Layer-2 network. To configure redundancy as described in the conceptual overview for master-local
