MSTI Priorities:
MSTI Priorities Settings menu allows configuring bridge priority to be used by MSTP
protocol. It is allowed to configure in this field the CIST priority and MSTI priority.
CIST priority field is the default instance, which matches with the instance used by
STP and RSTP protocols. Thus, this is the value of priority used in these protocols. CIST
priority field is interlocked with the Protocol Version configured in the Bridge Settings
menu, that is, configuring it at the Bridge Settings menu will change its value in the
MSTI Priorities menu, and the same if it is changed at the MSTI Priorities menu.
MSTI priority field is the value used by the bridges that supports MSTP protocol to
elect the root bridge in a given region.
If one configuration is desired to be applied at all instances, then the row “*” should
be use
d, that is, configuration done in the “*” row will be replied to all instances.
Possible configurations are as follows.
o
MSTI
: shows MSTI instance identifier given row of the table. The
first row displays the CIST instance, which is the default instance
used by STP and RSTP protocols. An MSTI instance will be
understood as the region in the MSTP protocol. Up to 7 instances
are supported by Reason Switches;
o
Priority
: indicates bridge priority to be used by MSTP protocol. To
define the root of the instance (the region root switch), this priority
is used as one of the parameters. Priority number plus MSTI
instance number and switch’s MAC address will be used as the
Bridge Identifier parameter in the MSTP network. Lower priority
numbers mean higher priority, Values allowed are from 0 to
61,440.
After one of the configurations described before is changed, there are buttons that
allow the user to save or discard the configurations.
