Figure 7-22. STP LAG Settings
The
STP LAG Settings
page contains the following fields:
Select a LAG
— The LAG number for which you want to modify STP settings.
STP
— Enables or disables STP on the LAG.
Fast Link
— Enables Fast Link mode for the LAG. If Fast Link mode is enabled for a LAG, the
LAG State
is automatically placed in the
Forwarding
state
when the LAG is up. Fast Link mode
optimizes the time it takes for the STP protocol to converge. STP convergence can take 30-60
seconds in large networks.
LAG State
— Current STP state of a LAG. If enabled, the LAG state determines what forwarding
action is taken on traffic. If the bridge discovers a malfunctioning LAG, the LAG is placed in the
Broken
state. Possible LAG states are:
Disabled
— STP is currently disabled on the LAG. The LAG forwards traffic while learning
MAC addresses.
