LABEL DESCRIPTION
Instance Enter the number you want to use to identify this MST instance on the Switch. The Switch
supports instance numbers 0 – 16.
Bridge Priority Set the priority of the Switch for the specific spanning tree instance. The lower the number, the
more likely the Switch will be chosen as the root bridge within the spanning tree instance.
Enter priority values between 0 and 61440 in increments of 4096 (thus valid values are 4096,
8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248, 57344 and
61440).
VLAN List Enter the VLAN ID range. You can specify multiple VLAN ID range separated by (no space)
comma (,) or hyphen (“-”) for a range. For example, enter “1,3,5-7” for VLANs 1, 3, 5, 6, and 7.
SLOT This field appears only in Stacking mode. Click the drop-down list to choose the slot number of
the Switch in a stack.
Port This field displays the port number. In Stacking mode, the first number represents the slot ID
and the second is the port number. Please note that the default stacking ports (the last four
ports of your Switch) cannot be configured. They are reserved for stacking only.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Active Select this check box to add this port to the MST instance.
