Tx Reinit
When a port is disabled, LLDP is disabled or the switch is rebooted, an LLDP
shutdown frame is transmitted to the neighboring units, signalling that the LLDP
information isn't valid anymore. Tx Reinit controls the amount of seconds between
the shutdown frame and a new LLDP initialization. Valid values are restricted to 1 -
10 seconds.
LLDP Port Configuration
The LLDP port settings relate to the currently selected stack unit, as reflected by the
page header.
Port
The switch port number of the logical LLDP port.
Mode
Select LLDP mode.
Rx only
The switch will not send out LLDP information, but LLDP information from
neighbor units is analyzed.
Tx only
The switch will drop LLDP information received from neighbors, but will
send out LLDP information.
Disabled
The switch will not send out LLDP information, and will drop LLDP
information received from neighbors.
Enabled
The switch will send out LLDP information, and will analyze LLDP
information received from neighbors.
CDP Aware
Select CDP awareness.
The CDP operation is restricted to decoding incoming CDP frames (The switch
doesn't transmit CDP frames). CDP frames are only decoded if LLDP on the port is
enabled.
Only CDP TLVs that can be mapped to a corresponding field 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 onto LLDP neighbors' table as shown below.
CDP TLV "Device ID" is mapped to the LLDP "Chassis ID" field.
CDP TLV "Address" is mapped to the LLDP "Management Address" field. The CDP
address TLV can contain multiple addresses, but only the first address is shown in
the LLDP neighbors table.
