Example for Applying an ACL to a VLAN 
Network requirements 
PC1, PC2 and PC3 belong to VLAN 10 and connect to the switch through GigabitEthernet 1/0/1, 
GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 respectively. The IP address of the database server is 
192.168.1.2. Apply an ACL to deny packets from PCs in VLAN 10 to the database server from 8:00 to 
18:00 in working days.
