What distinguishes MSM APs that implement a dynamic mesh link from HP MSM APs that
implement a static link?

A.
That APs using dynamic link can authenticate each other with 802.1X and receive the key for
encryption traffic sent on the link in that way.

B.
The APs using the dynamic link can automatically negotiate which channel to use and whether
to use channel bonding for 80211n.

C.
The APs using the dynamic link can establish new links between each other if one of the APs
fails.

D.
The APs using the dynamic link can negotiate the type of encryption that they will use
dynamically.

Static wireless mesh
– Dedicated, one-to-one wireless link between two autonomous APs
– Each autonomous AP supports six static wireless meshes.
A static wireless mesh is a dedicated, one-to-one wireless link between twoautonomous APs. The
APs bridge traffic across the static wireless mesh. The twonetwork segments connected by the
wireless mesh are on the same subnet. (The APsdo not route traffic.)
Dynamic wireless mesh
– One-to-one or one-to-many wireless links
– APs automatically:
• Establish links
• Reconfigure the wireless mesh if an AP is unavailable
A dynamic wireless mesh can support one-to-one links or one-to-many links. Withone-to-many
links, an AP can establish a wireless mesh with two or more APs.
Supported by both controlled and autonomous APs, the dynamic wireless mesh isdesigned to
provide redundancy and self-healing. You can design a wireless mesh sothat if one AP becomes
unavailable, the remaining APs can establish a link withanother AP, thereby maintaining a wireless
mesh. You will examine how thisreconfiguration works on the next page.
When an AP is configured to support a wireless mesh, it is called a node. As shownin the figure,
you can assign a node one of three roles in a dynamic wireless mesh,and these roles determine
how links are established.
-Master—The master provides the connection to the wired network. The masterdoes not initiate a
wireless link with alternate masters or slaves. Instead, themaster waits for these nodes to initiate a
wireless link with it.
-Alternate master—The alternate master first tries to establish an upstream linkwith a master or
another alternate master. The alternate master also waits forother alternate masters or slaves to
try to establish a link with it.
-Slave—A slave can establish an upstream link with a master or alternate master.
A slave cannot establish a downstream link with other slaves.

• Reconfigure the wireless mesh if an AP is unavailable
