The
STP LAG Settings
page contains the following fields:
•
Select a LAG
—Indicates the user-defined LAG. For more information on defining
LAGs, see
"
Defining LAG Membership
".
•
STP
—Enables STP on the LAG. The possible field values are:
–
Enable
—Enables STP on the LAG.
–
Disable
—Disables STP on the LAG.
•
Fast Link
—Enables Fast Link for the LAG. If Fast Link is enabled for a LAG, the LAG
is automatically placed in the
Forwarding State
. Fast Link optimizes the time it takes
for the STP protocol to converge (STP convergence can take 30-60 seconds in large
networks).
NOTE:
Use the
Fast Link
option only in appropriate cases; for example, when the device is a
leaf in the STP network topology for end stations.
•
LAG State
—Indicates the current STP state for 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
Disabled
state. The possible field
values are:
–
Disabled
—The link is currently down.
