DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch Figure 7- 47. LLDP Operation State Settings window The following parameters can be set: Parameter Description LLDP Operation State When this function is Enabled, the switch can start to transmit LLDP packets and receive and process the LLDP packets. The specific function of each port will depend on the per port LLDP setting. For the advertisement of LLDP packets, the switch announces the information to its neighbor through ports. For the receiving of LLDP packets, the switch will learn the information from the LLDP packets advertised from the neighbor in the neighbor table. LLDP Forward Message State Use the drop-down menu to disable or enable the LLDP forward message state. Message TX Interval This parameter indicates the interval at which LLDP frames are transmitted on behalf of this (5-32768) LLDP agent. The default value is 30 seconds. Message TX Hold Multiplier (2-10) This parameter is a multiplier that determines the actual TTL value by multiplying the message Tx interval * message Tx hold multiplier. The default value is 4. ReInit Delay (1-10) This parameter indicates the amount of delay from when adminStatus becomes "disabled" until re-initialization will be attempted. The default value is 2 seconds. TX Delay (1-8192) This parameter indicates the delay between successive LLDP frame transmissions initiated by value or status changes in the LLDP local systems MIB. The value for txDelay is set by the following range formula: 1 < txDelay < (0.25 × msgTxInterval) The default value is 2 seconds. Notification Interval Used to configure the timer of notification interval for sending notification to configured SNMP (5-3600) trap receiver(s). The default value is 5 seconds.
