MSM7xx Controllers Configuration Guide v6.4.0

AES/CCMP
Enables AES with CCMP encryption to secure traffic on the wireless link. This is the most secure
method.
The node uses the key you specify in the PSK field to generate the keys that encrypt the wireless
data stream.
Specify a key that is between 8 and 63 ASCII characters in length. HP recommends that the
key be at least 20 characters long and be a mix of letters and numbers.
Settings
Three different roles can be assigned to a node: master, alternate master, or slave. The role assigned
to a node, governs how the node will establish upstream or downstream links with its peers. The
available configuration settings change depending on the role that is selected.
• Master: The master is the root node that provides the upstream connection to the ground
network that the other nodes want to reach. The master will only create downstream local
mesh links to alternate master or slave nodes.
• Slave: Slave nodes can only establish upstream links with master or alternate master nodes.
Slave nodes cannot establish downstream links with other nodes.
• Alternate Master: An alternate master node must first establish an upstream link with a
master or alternate master node before it can establish downstream connections with an
alternate master or slave node.
