Tx Reinit:

Use this field to configure how long this switch waits to re-initialize a port after transmission of an LLDP shutdown frame. An LLDP shutdown
frame is transmitted to neighboring units to indicate the LLDP information is invalid (e.g. because a port is disabled, LLDP is disabled or the
switch is rebooted). Valid values are from 1 to 10 seconds.
Port:

This field shows the port number for this row.
Mode:

Use this drop-down box to configure whether the switch sends, receives or sends and receives LLDP frames. Possible values are:
Rx only: The switch receives but doesn't transmit LLDP information.

Tx only: The switch transmits but doesn't receive LLDP information.

Disabled: The switch receives and transmits LLDP information.

Enabled: The switch doesn't receive or transmit LLDP information.

CDP Aware:

Use this check box to enable the switch to decode incoming CDP frames. The switch doesn't transmit CDP frames and CDP frames are
only decoded if LLDP on the port is enabled. Only CDP TLVs that can be mapped to corresponding fields in the LLDP neighbors' table are
decoded. All other TLVs are discarded (unrecognized CDP TLVs and discarded CDP frames are not shown in the LLDP statistics). CDP
TLVs are mapped to the LLDP neighbors' table as follows.
The CDP Device ID is mapped to the LLDP Chassis ID.

The CDP Address is mapped to the LLDP Management Address. The CDP Address can contain multiple addresses, but only the first

address is shown in the LLDP neighbors' table.
The CDP Port ID is mapped to the LLDP Port ID.

The CDP Version and Platform TLV is mapped to the LLDP System Description TLV.

CDP and LLDP both support a system capabilities TLV, but CDP capabilities cover capabilities that are not part of LLDP. These capabilities
are shown as other in the LLDP neighbors' table. If all ports have CDP awareness disabled the switch forwards CDP frames received from
neighbor devices. If at least one port has CDP awareness enabled all CDP frames are terminated by the switch.
