Advanced ACL Configuration Example

Network requirements
Different departments of an enterprise are interconnected through a switch. The R&D department is
connected to Ethernet 1/0/1 of the switch. Apply an ACL to deny requests from the R&D department and
destined for Internet (TCP packets with the destination port number of 80) during the working hours
(8:00 to 18:00).
The R&D department is connected to Ethernet 1/0/1 of the switch. Apply an ACL to deny requests from
the R&D department to the wage server (TCP packets with the destination port number of 80) during
the working hours (8:00 to 18:00).

Layer 2 ACL Configuration Example

Network requirements
PC 1 and PC 2 connect to the switch through Ethernet 1/0/1. PC1's MAC address is 0011-0011-0011.
Apply an ACL to filter packets with the source MAC address of 0011-0011-0011 from 8:00 to 18:00
everyday.
