Question

In LLDP, what are the default values for Update Frequency and Hold Timer?

a) Update Frequency: _____ seconds
b) Hold Timer: _____ seconds

Answer 1

The default values for LLDP's Update Frequency and Hold Timer are 30 seconds and 120 seconds respectively. These timers regulate the frequency of LLDP messages and the time receivers should hold the information.

Step-by-step explanation:

In LLDP (Link Layer Discovery Protocol), the default values for the Update Frequency and Hold Timer are as follows:

• Update Frequency: 30 seconds
• Hold Timer: 120 seconds

LLDP is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network, based on a standardized form of Ethernet frame. The Update Frequency dictates how often an LLDP device sends out LLDP advertisements. The Hold Timer is related to the amount of time a receiving device should hold the information sent by an LLDP device before discarding it, effectively it indicates the time in seconds that an LLDP entry remains valid.
