Description
This command is used to enable or disable transmitting LLDP-MED TLVs. It effectively disables
LLDP-MED on a per-port basis by disabling transmission of TLV capabilities. In this case, the
remote table’s objects in the LLDP-MED MIB corresponding to the respective port will not be
populated.
Format
config lldp_med ports [<portlist> | all] med_transmit_capabilities [all | {capabilities |
network_policy | power_pse | inventory}(1)] state [enable | disable]
Parameters
<portlist> - Specify a range of ports to be configured.
all - Specify to set all ports in the system.
med_transit_capabilities - Select to send the LLDP-MED TLV capabilities specified.
all - Select to send capabilities, network policy, and inventory.
capabilities - Specify that the LLDP agent should transmit “LLDP-MED capabilities TLV.” If a
user wants to transmit LLDP-MED PDU, this TLV type should be enabled. Otherwise, this
port cannot transmit LLDP-MED PDU.
network_policy - Specify that the LLDP agent should transmit “LLDP-MED network policy
TLV.”
power_pse - Specify that the LLDP agent should transmit 'LLDP-MED extended Power via
MDI TLV' if the local device is a PSE device.
