AP MAC Address is the device MAC address. Ensure that this is the actual hard-coded MAC address
of the device. File Name is the name of the AP image. Server IP Address gives you the IP address of
the SFTP server where all the AP images reside. User ID is the ID to log in to the SFTP server.
Password is the SFTP password used while logging in. Path gives you the path of the AP image
residing in the server.

Multiple Spanning Tree

Multiple Spanning Tree Protocol (MSTP) provides a VLAN-aware protocol and algorithm to create
and maintain a loop-free network. It allows the configuration of multiple spanning tree instances.
This ensures a loop-free topology for one or more VLANs. It allows the network administrator to
provide a different path for each group of VLANs to better utilize redundancy.
MSTP allows rapid convergence similar to Rapid Spanning Tree Protocol (RSTP). RSPT is an
independent protocol and MSTP does not use RSTP. Since MSTP allows VLANs to be grouped in an
instance, each instance can have its own spanning-tree topology independent of other
spanning-tree instances. This architecture provides multiple forwarding links for data traffic and
load balancing, and therefore reduces the number of spanning-tree instances required to support
a large number of VLANs.
Using MSTP, the network can be divided into regions. All switches within a region use the same
VLAN to instance mapping. The entire network runs a spanning tree instance called the Common
Spanning Tree instance (CST) that interconnects regions as well as legacy (STP and RSTP) bridges.
The regions run on a local instance for each configured MSTP instance.
The network-wide spanning tree for instance 0 is known as the Common Spanning Tree (CST). A
spanning tree for any other instance, which is local to a region, is known as an Internal Spanning
Tree (IST). The Common and Internal Spanning Tree (CIST) (which consists of the CST as well as all
ISTs across regions) interconnects all bridges in the network.
