Adding a preconfigured device to the network
Page 36 | How to Configure and Use AMF on Allied Telesis Switches
In order to retain connectivity to the AMF network, AMF link and crosslink settings should
not be changed. In the example above you can see that port1.0.5 is an automatically
configured ATMF link. You can see the error message indicating it was skipped by the
switchport mode access command, as AMF links must be in trunk mode.
Warning: No changes should be made to the device's configuration while a node recovery is
underway. A log message will appear on the console or other logged in session indicating
when recovery has finished (whether successfully or with errors). This message can also
be found by viewing the log with the show log command.
Adding a preconfigured device to the network
In many cases when a new device is to be added to the network, a user will want to fully pre-
configure it before connecting it to the network. This is for the obvious reason that it is
generally not a good idea to have an unconfigured device connected to the network.
With AMF it is possible to perform this pre-configuration by cloning the configuration from
the backup of an existing AMF node. The cloned configuration will be applied in a safe way to
the similar node that you wish to join the AMF network. In this way a node can be added to
the network without the need to construct the configuration elements that are common to
another node.
There are two methods that can be used to achieve this:
1. By connecting an unconfigured clean node (see section "A “Clean” node" on page 31),
to the AMF network. Wait for automatic node recovery to fail and the AMF safe
configuration to be applied. Then use the atmf recover command, followed by the node
name of a similar node, to replicate the desired configuration to the new unit.
2. By preconfiguring the new device with the AMF network name, a node name, and an AMF
link prior to connecting it to the AMF network. Then use the atmf recover command
followed by the node name of a similar node, to replicate the desired configuration to the
new unit.
In both methods it is necessary to configure an AMF link on the neighboring node that is to
be connected to the new node, so the new node will be able to join the AMF network.
Note: It is recommended that the donor node selected is as close as possible to the new
node, and contains the same number of ports or if applicable, has the same XEMs
installed in the same bays. This will limit the number of manual changes that will be
required to the replicated configuration of the new node.
If using the first method described above, it is safe to connect ports other than the AMF link.
This is because forwarding will be disabled and all ports administratively shutdown when the
AMF safe configuration is applied.
If using the second method described above, it is important to only connect the atmf-link
until the configuration can be appropriately edited and the node rebooted. Following this
