Chapter 18: Setting LLDP and LLDP-MED

Non Strict Med TLV Order Check— Sets the switch to accept LLDP-MED advertisements even if the TLVs are not in the standard order, as specified in ANSI/TIA-1057. This configuration is useful if the switch is connected to devices that send LLDP-MED advertisements in which the TLVs are not in the standard order. Click in the box next to this field to select the nonstrict Med TLV Order Check.

Notification Interval— Sets the notification interval. This is the minimum interval between LLDP SNMP notifications (traps). The range is 5 to 3,600 seconds.

Reinit— Sets the reinitialization delay. This is the number of seconds that must elapse after LLDP is disabled on a port before it can be reinitialized. The range is 1 to 10 seconds.

Tx Delay— Specifies the transmission delay. This is the minimum time interval between transmissions of advertisements due to changes in LLDP local information.

Total Neighbors— Indicates the number of LLDP neighbors the switch has discovered on all its ports. You cannot modify this field.

Neighbors Last Update— Indicates the time since the LLDP neighbor table was last updated. You cannot modify this field.
