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.
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 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.
Note: When CDP awareness on a port is disabled, the CDP information isn't removed immediately, but
gets removed when the hold time is exceeded.
