Refer to the exhibit.

A network engineer must update the configuration on Switch2 so that it sends LLDP packets every minute and the information sent through LLDP is refreshed every 3 minutes. Which configuration should the engineer apply?

A Switch2(config)#lldp timer 60 Switch2(config)#lldp tlv-select 180
B Switch2(config)#lldp timer 60 Switch2(config)#lldp holdtime 180
C Switch2(config)#lldp timer 1 Switch2(config)#lldp holdtime 3
D Switch2(config)#lldp timer 1 Switch2(config)#lldp tlv-select 3

Explanation

On Cisco switches, lldp timer sets the transmission interval for LLDP advertisements, while lldp holdtime sets the advertised TTL that tells neighbors how long to keep the received LLDP information before discarding it. To send advertisements every 60 seconds and have neighbors retain that information for 180 seconds, the correct commands are lldp timer 60 and lldp holdtime 180. The lldp tlv-select command is unrelated because it controls which TLVs are advertised, not timing values.
