Description
•
Enable MSTP
Enable or disable 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.
