This can be reproducible.įor our example, we will configure an Advanced Access List in the right router. We can allow a specific host to access to a specific server with a specific port. With this Advanced Access List Configuration, we can prevent the traffic from a specific network to a specific network. In this second example, we will focus on Advanced Access List Configuration. As you can see below, you can find the three rules in this Access List (ACL). To check the ACL, we can use “ display acl 2222” command. Because, we are trying to prevent or allow the traffic going out to this router. rule permit source 172.16.0.0 0.0.255.255Īnd lastly, we will add this ACL to the related interface through outbound. And we will allow the users, in the subnet 172.16.0.0/16 to access the router. With this Basic Access List Configuration, we will prevent the users on the subnet 10.1.1.0/24 and 10.2.2.0/24 to access the router. In the first example, we will focus on Basic Access List Configuration. You will see a list of all the network interfaces with their MAC addresses (Ethernet Address).Basic Access List Configuration on Huawei Routers.Go to Utilities (Finder > Utilities OR command + shift + u) and start the Terminal app.You should see the MAC address in this format 00:00:00:00:00:00 following HWaddr In the terminal, type ifconfig and press ENTER.

IAB is also known as Individual Address Blocks and the number of addresses is 2 24 or 16 million. MA-S, or MAC Address Block Small, is a block of MAC addresses where the maximum of addresses is 2 12 or 4096. MA-M, or MAC Address Block Medium, is a block of MAC addresses where the maximum number of addresses is 2 20 or 1 million. MA-L, or MAC Address Block Large is a block of MAC addresses where the maximum number of addresses is 2 24 or 16 million. The OUI is basically the first three octets of a MAC address. They are purchased and assigned by the IEEE. They can either be written in either of these formats:Īn OUI is a 24-bit number that uniquely identifies a vendor or manufacturer. It is a 48-bit number (12 hexadecimal characters). No.2 Xin Cheng Road, Room R6,Songshan Lake Technology Park Dongguan 523808 CNĬoming up: MAC address API What is a MAC address? What is OUI?
