We know that access to files is based on the three types of files belonging to the owner, group, and other users, and ACLs provide more detailed permission settings beyond those three. ACLs can set permissions on single users and directories and files, which is useful for special permissions. Suid and Sgid These special permissions that were mentioned earlier, but these special permissions and

Create three VLANs: vlan10 vlan20 vlan30 www.2cto.com PC1 PC3 vlan10 PC2 PC4 vlan20 PC5 vlan30Vlan10 vlan20 vlan30 cannot communicate with each other but can access the Internet Pc1: 172.16.10.2 pc2: 172.16.20.2 pc3: 172.16.10.3 pc4: 172.16.20.3 pc5: 172.16.30.2 configure R1Int f0/0Ip add 192.168.1.2 255.255.255.0 configure f0/0No shInt lo0Ip add 1.1.1.1 255.255.255.0 configure the loopback IP a
