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, Signaling 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.
