Figure 4 Network diagram for IP subnet-based VLAN configuration

Network Requirements

As shown in Figure 4, hosts in the office area are configured on two network segments 192.168.5.0/24 and 10.200.50.0/24. Configure IP subnet-based VLANs on the switch to enable GigabitEthernet 1/0/1 of the switch to transmit packets received from different network segments in different VLANs to the corresponding gateways (Router A and Router B).
Packets from network segment 192.168.5.0/24 are transmitted in VLAN 100, and packets from network segment 10.200.50.0/24 are transmitted in VLAN 200.

Configuration Example

 ip-subnet-vlan 0 ip 10.200.50.0 255.255.255.0
#
interface GigabitEthernet1/0/1
 port link-type hybrid
 port hybrid vlan 1 100 200 untagged
 port hybrid ip-subnet-vlan vlan 100
 port hybrid ip-subnet-vlan vlan 200

There was one of the major flaws in the older Windows operating-system where, by standard, all users can see each other people's information (Windows 95, 98, Me).

They fully support file & directory permissions, just as Linux system has since the beginning. Together, we'll now assess a directory listing from our Lab Linux system hosting server, to help us understand the information provided. a simple 'ls' command will give you the file and directory listing within a given directory, including the option  '-l' will display number of new areas that we are going to discuss here:
