LLDP Parameters
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol.
LLDP information is sent by devices from each of their interfaces at a fixed interval,
in the form of an Ethernet Frame. Each frame contains one LLDP Data Unit
(LLDPDU). Each LLDPDU is a sequence of Type-Length-Value (TLV) structures.
Each LLDP frame starts with the following mandatory TLVs: Chassis ID, Port ID, and
Time-to-Live. The mandatory TLVs are followed by any number of optional TLVs.
This section allows the user to inspect and configure the current LLDP port settings.
LLDP Configuration
Tx Interval
The switch periodically transmits LLDP frames to its neighbors for having the
network discovery information up-to-date. The interval between each LLDP frame is
determined by the Tx Interval value. Valid values are restricted to 5 - 32768
seconds.
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.
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.
