3Configuring the SwitchCommand Attributes• LLDP – Enables LLDP globally on the switch. (Default: Enabled)• Transmission Interval – Configures the periodic transmit interval for LLDPadvertisements. (Range: 5-32768 seconds; Default: 30 seconds)This attribute must comply with the following rule:(Transmission Interval * Hold Time Multiplier) ≤ 65536, andTransmission Interval >= (4 * Delay Interval)• Hold Time Multiplier – Configures the time-to-live (TTL) value sent in LLDPadvertisements as shown in the formula below. (Range: 2-10; Default: 4)The time-to-live tells the receiving LLDP agent how long to retain all informationpertaining to the sending LLDP agent if it does not transmit updates in a timelymanner.TTL in seconds is based on the following rule:(Transmission Interval * Holdtime Multiplier) ≤ 65536.Therefore, the default TTL is 4*30 = 120 seconds.• Delay Interval – Configures a delay between the successive transmission ofadvertisements initiated by a change in local LLDP MIB variables.(Range: 1-8192 seconds; Default: 2 seconds)The transmit delay is used to prevent a series of successive LLDP transmissionsduring a short period of rapid changes in local LLDP MIB objects, and to increasethe probability that multiple, rather than single changes, are reported in eachtransmission.This attribute must comply with the rule: (4 * Delay Interval) ≤ Transmission Interval• Reinitialization Delay – Configures the delay before attempting to re-initializeafter LLDP ports are disabled or the link goes down. (Range: 1-10 seconds;Default: 2 seconds)When LLDP is re-initialized on a port, all information in the remote systems LLDPMIB associated with this port is deleted.• Notification Interval – Configures the allowed interval for sending SNMPnotifications about LLDP MIB changes. (Range: 5-3600 seconds; Default: 5seconds)This parameter only applies to SNMP applications which use data stored in theLLDP MIB for network monitoring or management.Information about changes in LLDP neighbors that occur between SNMPnotifications is not transmitted. Only state changes that exist at the time of anotification are included in the transmission. An SNMP agent should thereforeperiodically check the value of lldpStatsRemTableLastChangeTime to detect anylldpRemTablesChange notification-events missed due to throttling or transmissionloss.• MED Fast Start Count – Configures the amount of LLDP MED Fast StartLLDPDUs to transmit during the activation process of the LLDP-MED Fast Startmechanism. (Range: 1-10 packets; Default: 4 packets)3-252
