[SwitchA-vlan2] quit
# Set the link type of GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 to trunk and enable voice
VLAN on them.

# 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.
