# Configure the suppression time of physical-link-state changes on GigabitEthernet 1/0/1,
GigabitEthernet 1/0/2, and GigabitEthernet 1/0/3 as zero, disable STP, configure the ports as trunk
ports, and assign them to all VLANs, and configure them to trust the 802.1p precedence of the
received packets.
