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 AMF link. You can see the error message indicating it was skipped by the
switchport mode access command on page 17.15 , because AMF links must be in trunk
mode.
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
preconfigure 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 preconfiguration 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 59.28 ), 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 switch.
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.
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.
atmf1[2](config-if)# no shutdown
atmf1[2](config-if)# exit
atmf1[2](config-if)# vlan database
atmf1[2](config-if)# no vlan 4090
atmf1[2](config-if)# end
Caution 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 on page 10.37 .
Note We recommend that you select the donor node to be as close as possible to the
new node, and for it to contain 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.
