2. Tx Hold :
Each LLDP frame contains information about how long the information in the
LLDP frame shall be considered valid. The LLDP information valid period is set to
Tx Hold multiplied by Tx Interval seconds. Valid values are restricted to 2 - 10
times.
3. Tx Delay :
If some configuration is changed (e.g. the IP address) a new LLDP frame is
transmitted, but the time between the LLDP frames will always be 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.
4. 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
1. Port :
The switch port number of the logical LLDP port.
2. 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.
3. 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
