# Enable LLDP (you can skip this step because LLDP is enabled on ports by default), configure LLDP to
operate in TxRx mode, and configure CDP-compatible LLDP to operate in TxRx mode on
GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2.

3) Verify the configuration
# Display the neighbor information on Switch A.

As the sample output shows, Switch A has discovered the IP phones connected to GigabitEthernet
1/0/1 and GigabitEthernet 1/0/2, and has obtained their LLDP device information.
