User-defined ACL Configuration Example
Network requirements
As shown in Figure 1-6 , PC 1 and PC 2 are connected to the switch through Ethernet 1/0/1
and Ethernet 1/0/2 respectively. They belong to VLAN 1 and access the Internet through
the same gateway, which has an IP address of 192.168.0.1 (the IP address of
VLAN-interface 1).
Configure a user-defined ACL to deny all ARP packets from PC 1 that use the gateway IP
address as the source address from 8:00 to 18:00 everyday.
