MSTP
The Multiple Spanning Tree Protocol (MSTP) algorithm and protocol provides simple and full connectivity for frames assigned to any given VLAN throughout a Bridged Local Area Network comprising arbitrarily interconnected Bridges, each operating MSTP, STP (Clause 8 of IEEE Std 802.1D, 1998 Edition), or RSTP (Clause 17 of IEEE Std 802.1D,1998 Edition).
MSTP allows frames assigned to different VLANs to follow separate paths, each based on an independent Multiple Spanning Tree Instance (MSTI), within Multiple Spanning Tree (MST) Regions composed of LANs and or MST Bridges. These Regions and the other Bridges and LANs are connected into a single Common Spanning Tree (CST).
Enable MSTP
Enables or disables MSTP capability.
Region Name
Specifies the configuration region name. The name string
has a maximum length of 32 characters and is case sensitive.
Revision Level
Specifies the configuration revision level. The range is
0 to 65535.
Max Age
Configures the maximum age of the current bridge. This is
the maximum age of spanning tree protocol information learned from the network
on any port before it is discarded.
Forward Delay
Forward delay is a time value which controls how fast a
port changes its state. The value determines how long the port stays in each
of the listening and learning states which precede the forward state. This
value is also used to age all dynamic entries in the forwarding databases when
a topology change has been detected and is underway.
Note: Max Age <= 2*(Forward Delay-1)
Max Hops
Specifies the number of hops in a region before the BPDU is
discarded and the information held for a port is aged.
