www.dell.com | support.dell.com Path Cost (1-200000000) - Amount the LAG contributes to the root path cost. The path cost is adjusted to a higher or lower value, and is used to forward traffic when a path is being rerouted. The path cost has a value of 1 to 200000000. Default Path Cost - Indicates if the default path cost is used. The possible LAG path cost default values are: Long Method for LAG - 20,000 Short Method for LAG - 4 Priority (0-240, in steps of 16) - Priority value of the LAG. The priority value influences the LAG choice when a bridge has looped ports. The priority value is between 0-240, in steps of 16. Designated Bridge ID - The priority and the MAC Address of the designated bridge. Designated Port ID - The ID of the selected interface. Designated Cost - Cost of the port participating in the STP topology. Ports with a lower cost are less likely to be blocked if STP detects loops. Forward Transitions - Number of times the LAG State has changed from the Forwarding state to a Blocking state.
