PARAMETERS
These parameters are displayed:
◆ MSTI – Instance identifier to configure. (Range: CIST, MIST1-7)
◆ Priority – The priority of a spanning tree instance. (Range: 0-240 in steps of 16; Options:
0, 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240; Default: 128)
Bridge priority is used in selecting the root device, root port, and designated port. The device
with the highest priority becomes the STA root device. However, if all devices have the same
priority, the device with the lowest MAC address will then become the root device. Note that
lower numeric values indicate higher priority. The bridge priority plus the MSTI instance
number, concatenated with the 6-byte MAC address of the switch forms a Bridge Identifier.
WEB INTERFACE
To add VLAN groups to an MSTP instance:
1. Click Configuration, Spanning Tree, MSTI Priorities.
2. Set the bridge priority for the CIST or any configured MSTI.
3. Click Save
CIST Ports
Use the CIST Ports Configuration page to configure STA attributes for interfaces when the
spanning tree mode is set to STP or RSTP, or for interfaces in the CIST. STA interface
attributes include path cost, port priority, edge port (for fast forwarding), automatic detection
of an edge port, and point-to-point link type.
You may use a different priority or path cost for ports of the same media type to indicate the
preferred path, edge port to indicate if the attached device can support fast forwarding, or link
type to indicate a point-to-point connection or shared-media connection. (References to
