The following table describes the items in the previous figure.
STP Mode The Spanning Tree Protocol (STP) Administrative Mode associated
with the port or LAG. STP is a layer 2 protocol that provides a tree
topology for switches on a bridged LAN. STP allows a network to have
redundant paths without the risk of network loops. by providing a sin-
gle path between end stations on a network. The possible values for
STP mode are:

Enable: Spanning tree is enabled for this port.

Disable: Spanning tree is disabled for this port.
LACP Mode Shows the administrative mode of the Link Aggregation Control Proto-
col (LACP), which is one of the following:

Enabled: The port uses LACP for dynamic LAG configuration.
When LACP is enabled, the port sends and receives LACP
PDUs with its link partner to confirm that the external switch is
also configured for link aggregation.

Disabled: The port is supports static LAG configuration only.
This mode might be used when the port is connected to a device
that does not support LACP. When a port is added to a LAG as a
static member, it neither transmits nor receives LACP PDUs.
Link Status Indicates whether the link is up or down. The link is the physical con-
nection between the port or LAG and the interface on another device.
