ARAMETERS
These parameters are displayed on the MSTP Edit MSTI/ VLAN page:

Priority – The priority parameter used in the CIST(Common and
Internal Spanning Tree) connection. The available value shows as
below:
0 / 4096 / 8192 / 12288 / 16384 / 20480 / 24576 / 28672 / 32768 /
36864 / 40960 / 45056 / 49152 / 53248 / 57344 / 61440.

MAX. Age - The same definition as in the RSTP protocol. The Range
is from 6 to 40 sec.

Forward Delay - The same definition as in the RSTP protocol. The
Range is from 4 to 30 sec.

MAX. Hops - 6-40sec. It‘s a new parameter for the multiple
spanning tree protocol. It is used in the internal spanning tree
instances. ―CIST Remaining Hops‖ or ―MSTI Remaining Hops‖ in the
Spanning tree protocol message would decreased by one when the
message is propagated to the neighboring bridge. If the Remaining
Hops in a message is zero, the message (BPDU) would be regarded
as invalid. Max Hops is used to specify the initial value of the
Remaining Hops for Regional Root Bridge (Either CIST Regional
Root or MSTI Regional Root)
