LLDP Configuration Workflow
Following are examples of actions that can be performed with the LLDP feature and in a
suggested order. You can refer to the LLDP/CDP section for additional guidelines on LLDP
configuration. LLDP configuration pages are accessible under the
LLDP and CDP section.
1. Enter LLDP global parameters, such as the time interval for sending LLDP updates using
the LLDP Properties page.
2. Configure LLDP per port by using the Port Settings page. On this page, interfaces can be
configured to receive/transmit LLDP PDUs, send SNMP notifications, specify which TLVs
to advertise, and advertise the device's management address.
3. Create LLDP MED network policies by using the LLDP MED Network Policy page.
4. Associate LLDP MED network policies and the optional LLDP-MED TLVs to the desired
interfaces by using the LLDP MED Port Settings page.
5. If Auto Smartport is to detect the capabilities of LLDP devices, enable LLDP in the
Properties page.
6. Display overloading information by using the LLDP Overloading page.
