IPv4 packet filtering configuration example

Network requirements

As shown in

Figure 2

, Host A and Host B connect to the switch to access the Internet.

Configure packet filtering on the VLAN interface of the switch so that everyday from 8:00 to 18:00, the

VLAN-interface denies only IPv4 packets sourced from Host A. Configure the switch to output IPv4 packet
filtering logs to the console at 10-minute intervals.
As actual requirements change, edit the ACL so that the VLAN interface denies only IPv4 packets sourced

from Host B.
