Configuring STP/RSTP/CIST Interfaces

Use the STP CIST Port 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.

Instance identifier to configure. (Range: CIST, MIST1-7)
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.
Port identifier. This field is not applicable to static trunks or dynamic trunks created
through LACP. Also, note that only one set of interface configuration settings can
be applied to all trunks.
Sets the interface to enable STA, disable STA, or disable STA with BPDU trans-
parency. (Default: Enabled)
BPDU transparency is commonly used to support BPDU tunneling, passing
BPDUs across a service provider's network without any changes, thereby combin-
ing remote network segments into a single spanning tree. As implemented on this
switch, BPDU transparency allows a port which is not participating in the spanning
tree (such as an uplink port to the service provider's network) to forward BPDU
packets to other ports instead of discarding these packets or attempting to pro-
cess them.
