Infrastructure and Design

At a customer site, IP phones are not receiving IP addresses from DHCP. An engineer must temporarily disable LLDP on every switch port so that only CDP remains.

Which two commands accomplish this task?

Choose two
  • A Switch(config)# no lldp transmit
  • B Switch# configure terminal
  • C Switch# copy running-config startup-config
  • D Switch(config)# no lldp run
  • E Switch(config)# interface GigabitEthernet1/0/1
Explanation

In Cisco IOS, configure terminal enters global configuration mode, where no lldp run disables LLDP globally across the switch. An interface-level no lldp transmit command affects only LLDP transmission on one selected interface and does not disable LLDP on all ports.
