Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) Changing the Time-to-Live for Transmitted Advertisements. The Time-to-Live value (in seconds) for all LLDP advertisements transmitted from a switch is controlled by the switch that generates the advertisement, and determines how long an LLDP neighbor retains the advertised data before discarding it. The Time-to-Live value is the result of multiplying the refreshinterval by the holdtime-multiplier described below. Syntax lldp holdtime-multiplier < 2 - 10 > Changes the multiplier an LLDP switch uses to calculate the Time-to-Live for the LLDP advertisements it generates and transmits to LLDP neighbors. When the Time-to-Live for a given advertisement expires the advertised data is deleted from the neighbor switch's MIB. (Default: 4; Range: 2 - 10) For example, if the refresh-interval on the switch is 15 seconds and the holdtime-multiplier is at the default, the Time-to-Live for advertisements transmitted from the switch is 60 seconds (4 x 15). To reduce the Time-to-Live, you could lower the holdtime-interval to 2, which would result in a Time-toLive of 30 seconds. ProCurve(config)# lldp holdtime-multiplier 2 Changing the Delay Interval Between Advertisements Generated by Value or Status Changes to the LLDP MIB. The switch uses a delayinterval setting to delay transmitting successive advertisements resulting from these LLDP MIB changes. If a switch is subject to frequent changes to its LLDP MIB, lengthening this interval can reduce the frequency of successive advertisements. The delay-interval can be changed using either an SNMP network management application or the CLI setmib command. 13-48
