CONFIGURING
STP/RSTP/CIST
INTERFACES
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 “ports” in this
section means “interfaces,” which includes both ports and trunks.)

PARAMETERS
These parameters are displayed:
◆ Port – 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.
◆ STP Enabled – Sets the interface to enable STA, disable STA, or
disable STA with BPDU transparency. (Default: Enabled)
BPDU transparency is commonly used to support BPDU tunneling,
passing BPDUs across a service provider’s network without any
changes, thereby combining remote network segments into a single
