CST Port Configuration
Description Factory Default
Interface
This field displays the interface number or port channel number.
interface number
Port Priority
Enter the priority for the interface in the CIST. Enter a value between 0
and 240 that is a multiple of 16. The default priority is 128.
128
Admin Edge Port
Specify whether the interface is an edge port in the CIST:
 Enable: The interface is an edge port.
 Disable: The interface is not an edge port.
Disable
Port Path Cost
Leave the existing path cost, or enter a new path cost that is used for
the interface in the CIST. Enter a number in the range of 1 to
200,000,000. Enter a blank (that is, remove the number and make sure
there is no space character in the field) to reset the path cost.
20000
Auto Calculated Port Path Cost
This field shows whether you have globally enabled or disabled the
dynamic path cost on the CST Configuration screen.
Disable
Hello Timer
The hello time for the interface in the CIST. This time is the period in
seconds that the interface waits between configuration messages.
Enter 1 or 2 seconds. The default is 2 seconds.
Notice:
You can set the hello time only when the STP operation mode
is MSTP.
2
BPDU Forwarding
Specify whether the interface sets the mcheck flag to forward BPDUs:
 Enable: Depending on the STP operation mode, RST or MST
BPDUs are forwarded.
 Disable: BPDUs are not forwarded.
Disable
Auto Edge
Specify whether the interface automatically becomes an edge port if it
does not process BPDUs for a while:
 Enable: The interface becomes an edge port.
 Disable: The interface does not become an edge port.
Enable
Root Guard
Specify whether the root guard mode can cause the interface to discard
any superior information received by the interface to prevent the root of
the device from changing. When this situation occurs, the interface
enters the discarding state and no longer forwards any packets:
 Enable: The interface can enter the discarding state.
 Disable: The interface cannot enter discarding state.
Disable
TCN Guard
Specify whether the topology change notification (TCN) guard restricts
the interface from propagating topology change information:
 Enable: The interface can propagate topology change information.
 Disable: The interface cannot propagate topology change
information.
