What is Voice VLAN? How to use IP Phones on our network?
Voice VLAN is used to provide voice traffic with a dedicated VLAN. Voice traffic is isolated from other network traffic and so it doesn’t slow down the network. In order to make a work voice vlan and computer together, you should turn on the voice vlan in your cisco phone. This is done by providing […]
What is VTP (VLAN Trunking Protocol) ?
A VTP server is a switch to which other switches are connected. The VTP server maintains the VLAN database and propagates it to all the other switches. There are three modes in which a VTP server can operate: Server, Client and Transparent. The Server mode is used when there is more than one switch in […]

Extended ACL list for enterprise network system. Download
In this simulation you can find all necessary configuration. You can download .pkt Cisco Package Tracer file and open it on your computer. There are 5 VLAN configured and 1 extended ACL implemented on whole VLANs. Basically, hit CLI tab on the switch which you want to check then enter “show running-configuration” command to see […]
Inter-VLAN Communication (Routing) and Extended ACL
Hello everyone, In this example we will create 4 VLANs on a mid-level network infrastructure. Above you can see the logical topology which we created. There is one DHCP server on 192.168.4.10/24 , one SQL-server on 192.168.3.2, four different client hosts and two layer-3 switches. We will use EXTENDED ACL to create some rules on […]
What is trunk port? How to use them on switches?
In this example, we will use 2 different switches, 2 different VLANs (VLAN 10 and VLAN 20). On each switches there will be a “trunk port” to carry all VLAN related data through 802.1Q protocol. Trunk ports are capable of carrying multiple VLAN data through the network. First, we will use 4 clients which are […]

Routing between networks / Cisco router configuration
HOW TO ROUTE NETWORKS USING CISCO ROUTERS ? In this example topology, we have 3 different networks. We have 192.168.1.0 network on the left side, 192.168.2.0 on the right side. Also 3rd network is between routers on 192.168.0.0 networks. So we will configure our topology as above. First let’s start with clients; give IP addresses […]
DHCP server configuration on Cisco switch
How to configure DHCP service on Cisco Layer 3 switch? Let’s assume that we have an imaginary network called CORPORATE. This network is 192.168.1.0 and the subnet mask is 255.255.255.0 (/24). At this example, we have 3 client notebook which get IP address from our internal DHCP server which is configured in Cisco switch. First […]
Basic VLAN Configuration on Cisco switches
Here you can find the logical topology which was created on Cisco package tracer. There are 3 different VLANs on this system. VLAN 10 is highlighted green, VLAN 2O is highlighted orange and VLAN 30 is used for server management. On this network topology, we have 4 clients, 1 layer-3 switch and 1 DHCP server […]
