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.
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 neighbour units is analyzed.
Tx only The switch will drop LLDP information received
from neighbours, but will send out LLDP information.
Disabled The switch will not send out LLDP information,
and will drop LLDP information received from neighbours.
Enabled The switch will send out LLDP information, and
will analyze LLDP information received from neighbours.
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 neighbours' 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 neighbours'
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
neighbours’ table.
CDP TLV "Port ID" is mapped to the LLDP "Port ID" field.
CDP TLV "Version and Platform" is mapped to the LLDP
"System Description" field.
Both the CDP and LLDP support "system capabilities", but
the CDP capabilities cover capabilities that are not part of
the LLDP. These capabilities are shown as "others" in the
LLDP neighbours' table.
If all ports have CDP awareness disabled the switch
forwards CDP frames received from neighbour devices. If at
least one port has CDP awareness enabled all CDP frames
are terminated by the switch.
Note: When CDP awareness on a port is disabled the CDP
information isn't removed immediately, but gets when the
hold time is exceeded.
Port Descr Optional TLV: When checked the "port description" is
included in LLDP information transmitted.
Sys Name Optional TLV: When checked the "system name" is
included in LLDP information transmitted.
