If some configuration is changed (for example, the IP address) a new LLDP
frame is transmitted, but the time between the LLDP frames is always at
least the value of Tx Delay seconds. Tx Delay cannot be larger than 1/4 of
the Tx Interval value. Valid values are restricted to 1 - 8192 seconds.
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.
The switch port number of the logical LLDP port.
Select LLDP mode.
•
Rx only The MP1204-XT does not send out LLDP information, but LLDP
information from neighbor units is analyzed.
•
Tx only The MP1204-XT drops the LLDP information received from
neighbors, but sends out LLDP information.
•
Disabled The MP1204-XT does not send out LLDP information, and
drops the LLDP information received from neighbors.
•
Enabled The MP1204-XT sends out LLDP information, and analyzes the
LLDP information received from neighbors.
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.
