# Configuring LLDP Timers using EDM

Use the following procedure to configure LLDP Timers.
Note

LLDP timers apply to the entire device and cannot be configured by port.

## Procedure steps

1. From the navigation tree, double-click Edit.

2. In the Edit tree, double-click Diagnostics.

3. In the Diagnostics tree, double-click 802.1AB.

4. In the 802.1AB tree, click LLDP.

5. In the LLDP work area, click the Globals tab.

6. In the Globals section, configure timers as required.

7. On the toolbar, click Apply.

8. On the toolbar, you can click Refresh to verify the configuration.

## Variable definitions

The following table describes the variables associated with configuring LLDP timers.

Variable | Value
--- | ---
lldpMessageTxInterval | Indicates interval, in seconds, at which LLDP frames are transmitted on behalf of this LLDP agent. DEFAULT: 30s
lldpMessageTxHoldMultiplier | Indicates the time-to-live value expressed as a multiple of the object. The actual time-to-live value used in LLDP frames, transmitted on behalf of this LLDP agent, is expressed by the following formula: TTL = min(65535, (lldpMessageTxInterval *lldpMessageTxHoldMultiplier). DEFAULT: 4s
lldpReinitDelay | Indicates the delay (in seconds) from when the LLDP Port AdminStatus of a particular port is disabled until reinitialization begins. DEFAULT: 2s
lldpTxDelay | Indicates the delay (in seconds) between successive LLDP frame transmissions initiated by value or status changes in the LLDP local systems MIB. The recommended value for the lldpTxDelay is set by the following formula: 1 <= lldpTxDelay <= (0.25 * lldpMessageTxInterval) DEFAULT: 2s
lldpNotificationInterval | Controls the transmission of LLDP notifications. DEFAULT: 5s
