www.dell.com | support.dell.com Learning - The LAG is in the learning mode and cannot forward traffic, but it can learn new MAC addresses. Forwarding - The LAG is currently in the forwarding mode, and it can forward traffic and learn new MAC addresses. Broken - The LAG is currently malfunctioning and cannot be used for forwarding traffic. 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 being rerouted. The path cost has a value of 1 to 200000000. If the path cost method is short, the LAG cost default value is 4. If the path cost method is long, the LAG cost default value is 20000. Default Path Cost - When selected, the LAG path cost returns to its default value. Priority (0-240, in steps of 16) - The priority value of the LAG. The priority value influences the LAG choice when a bridge has two looped ports. The priority value is between 0-240, in increments of 16. Designated Bridge ID - The bridge priority and the MAC Address of the designated bridge. Designated Port ID - The port priority and interface number of the designated port. Designated Cost - The cost of the designated bridge. Forward Transitions - The number of times the LAG State has changed from the Blocking state to a Forwarding state.

Learning
— The LAG is in the learning mode and cannot forward traffic, but it can learn new MAC
addresses.
Forwarding
— The LAG is currently in the forwarding mode, and it can forward traffic and learn new MAC
addresses.
Broken
— The LAG is currently malfunctioning and cannot be used for forwarding traffic.
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 being rerouted. The path cost has a value of 1 to
200000000. If the path cost method is short, the LAG cost default value is 4. If the path cost method is long, the
LAG cost default value is 20000.
Default Path Cost
— When selected, the LAG path cost returns to its default value.
Priority (0-240, in steps of 16)
— The priority value of the LAG. The priority value influences the LAG choice
when a bridge has two looped ports. The priority value is between 0-240, in increments of 16.
Designated Bridge ID
— The bridge priority and the MAC Address of the designated bridge.
Designated Port
ID
— The port priority and interface number of the designated port.
Designated Cost
— The cost of the designated bridge.
Forward Transitions
— The number of times the
LAG State
has changed from the
Blocking
state to a
Forwarding
state.
