The fields that can be configured are described below:

Parameter Description

MSTI ID

Enter the MSTI ID in this field. An entry of 0 denotes the CIST (default MSTI).

Priority

Enter the priority in this field. The available range of values is from 0 to 61440.

Click the Apply button to accept the changes made.

Click the Edit button to re-configure the specific entry.

Click the View button to display the information of the specific entry.

MSTP Port Information

This window displays the current MSTI configuration information and can be used to update the port configuration for

an MSTI ID. If a loop occurs, the MSTP function will use the port priority to select an interface to put into the

forwarding state. Set a higher priority value for interfaces to be selected for forwarding first. In instances where the

priority value is identical, the MSTP function will implement the lowest MAC address into the forwarding state and

other interfaces will be blocked. Remember that lower priority values mean higher priorities for forwarding packets.

The fields that can be configured are described below:

Parameter Description

Port

Select the port you want to configure.

Instance ID

The MSTI ID of the instance to be configured. Enter a value between 0 and 15. An entry

of 0 in this field denotes the CIST (default MSTI).

Internal Path Cost (1-

200000000)

This parameter is set to represent the relative cost of forwarding packets to specified

ports when an interface is selected within an STP instance. Selecting this parameter with

a value in the range of 1 to 200000000 will set the quickest route when a loop occurs. A

lower Internal cost represents a quicker transmission. Selecting 0 (zero) for this

parameter will set the quickest route automatically and optimally for an interface.

Priority

Enter a value between 0 and 240 to set the priority for the port interface. A higher priority
