Description
Interface
This is a nonconfigurable field that shows the port number or LAG number.
STP Status
Specify the STP status for the port or LAG: 
Enable. STP is enabled for the port or LAG.
Disable. STP is disabled for the port or LAG. This is the default setting.
Fast Link
Specify whether the port or LAG functions as an edge port in the CST:
Enable. The port or LAG is an edge port.
Disable. The port or LAG is not an edge port. This is the default setting.
Port State
This is a nonconfigurable field that shows the forwarding state for the port or 
LAG:
Discarding. The port or LAG is in the discarding state; it cannot forward 
traffic and cannot learn new MAC addresses.
Learning. The port or LAG is in the learning state; it cannot forward traffic, 
but it can learn new MAC addresses.
Forwarding. The port or LAG is in the forwarding state; it can forward traffic 
and learn new MAC addresses.
Manual forwarding. The port or LAG is in the forwarding state but STP is 
disabled or the port is a trunk member (that is, the port is a member of a 
LAG).
Disabled. The port or LAG is disabled.
Path Cost
The path cost for the port or LAG in the CST. Enter a value in the range of 0 to 
200000000. By default, the path cost has a value of 0, which allows the path 
cost to be updated with an external path cost from received STP packets.
Priority
The priority for the port or LAG in the CST. Enter a value in the range of 0 to 240 
that is a multiple of 16. The default value is 128.
Port ID
This is a nonconfigurable field that shows the port ID for the port or LAG within 
the CST. The port ID is made up from the port priority (32768) and the interface 
number of the port, that is, the interface number of the port is added to 32768. 
The interface numbers of the LAGs (l1 through l8) are for this purpose 30 
through 36.
Hello Timer
This is a nonconfigurable field that shows the hello time for the port or LAG in 
the CST. This time is the period in seconds that the port or LAG waits between 
configuration messages. The value is fixed at 2 seconds.

Note:
 
You can refer to an edge port as a fast link.
Note:
 
If you specify a value that is not a multiple of 16, the priority is 
automatically adjusted to the next lowest priority that is a multiple of 16. For 
example, if you set a value between 0 and 15, the priority is adjusted to 0. If you 
specify a number between 16 and 31, the priority is adjusted to 16.
