| This attribute must comply with the following rule: | |
|
| (Transmission Interval * Hold Time Multiplier) ≤65536, and Transmission Interval | |
|
| >= (4 * Delay Interval) | |
|
|
|
|
• | 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. | |
|
| TTL in seconds is based on the following rule: | |
|
| (Transmission Interval * Holdtime Multiplier) ≤ 65536. | |
|
| Therefore, the default TTL is 4*30 = 120 seconds. | |
|
|
|
|
• | 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. | |
|
| This attribute must comply with the rule: | |
|
| (4 * Delay Interval) ≤Transmission Interval | |
|
|
|
|
• | Tx Reinit | When a port is disabled, LLDP is disabled or the switch is rebooted a 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. | |

4.14.2.2 LLDP Port Configuration
The LLDP port settings relate to the currently selected stack unit, as reflected by the page header.

Object | Description | |||
• | Port | The switch port number of the logical LLDP port. | ||
|
|
| ||
• | Mode | Select LLDP mode. | ||
|
| • |
| The switch will not send out LLDP information, but LLDP information |
|
| Rx only | ||
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.
