# Configure the suppression time of physical-link-state changes on GigabitEthernet 1/0/1 and
GigabitEthernet 1/0/2 as zero, disable STP, configure the two ports as trunk ports, remove them from
VLAN 1, and assign them to VLAN 10 and VLAN 20, and configure them to trust the 802.1p
precedence of the received packets.
