Spanning Tree Protocol policy

The Spanning Tree Protocol (STP) is a Layer 2 protocol that ensures a loop-free topology for any
bridged LAN (Layer-2 bridges are typically Ethernet switches). Spanning tree allows a network
design to include spare (redundant) links to provide automatic backup paths if an active link fails,
without the danger of bridge loops or the need to manually enable or disable these backup links.
NOTE
STP is not supported on internal ports.
Refer to

802.1x policy

802.1x is a standard authentication protocol that defines a client-server-based access control and
authentication protocol. 802.1x restricts unknown or unauthorized clients from connecting to a
LAN through publicly accessible ports.
Refer to

Link aggregation groups

Link aggregation, based on the IEEE 802.3ad protocol, is a mechanism to bundle several physical
ports together to form a single logical channel or trunk. The collection of ports is called a link
aggregation group (LAG). LAG configuration is not supported on internal ports.
The Add LAG button is enabled when a single CEE switch or ports of a single CEE switch are
selected. The Add LAG button is disabled when multiple switches are selected, ports from different
switches are selected, or LAGs are selected.
The Edit button is enabled when a single LAG, port, or switch is selected.
NOTE
When LLDP-DCBX, Access Control List (ACL), or Spanning Tree Protocol (STP) is disabled on the
switch, a yellow banner displays on the dialog box, indicating that LLDP-DCBX, ACL, or STP is not only
disabled on the switch, it is also disabled for all ports and LAGs on the switch.

Adding a LAG

You manage port selection using the Add LAG dialog.
NOTE
An internal port cannot be part of a LAG. You can create LAGs with external ports only.
1. Select Configure > Switch > CEE from the menu bar.
2. Select the CEE switch or one or more CEE ports to add to a link aggregation group (LAG).
