Configure dhcp on cisco router interface
It is not as hard as it sounds to configure DHCPD on Cisco routers. The process basically consists of three simple steps. The first step involves setting up an IP-based private local area network or LAN. Then you have to associate that Ethernet address with the DNS name for your private network. The third and last step is to configure DHCPD on the interface of your Cisco router.
Before starting, there are a few things that you should do to configure DHCPD. You need to be aware of the following. If any one of these steps are skipped then the whole process will be in vain.
Assign an IP-based private network. This step has to be followed precisely to ensure that you get the right settings. In most cases, you will have to include the IP addresses of all users in the private network. You also have to add the subnet mask of the private network.
Configure dhcp on cisco router interface
Enter the IP-based address of your domain name. You can do this by clicking on the name and typing it in the web browser. If you don’t want to type the IP address, you can enter the name in quotation marks. The names are separated by commas. After that you have to click on the Apply button.
On the Network settings, there should be a field named ‘dhcp’. You have to put the IP address of your router in the text box and then click on the Save button. When you save the setting, the changes will take effect immediately. If you want to configure DHCPD on a router automatically, you will have to leave the ‘dhcp’ option alone.
There are different ways in which you can add the name of a domain into the IP address of a Cisco switch. You will find them in the manuals of your Cisco devices or on the Internet. You can add the name by copying the IP address of the domain name or by typing the name and copying it to the IP address of the router. You will have to replace the periods with dots.
There are certain steps which you have to follow to change the IP address of the interface and also to change the DNS name for the given name. In both cases, you have to use the name servers. It is up to you to either use the name servers or not. Once you have saved the DNS name, you can change the IP address or not.
There are a couple of issues related to DHCPD on a Cisco router. The first issue is associated with the use of the interface when you are in a remote location. The second issue is related to the use of the DNS name for the interface. For both purposes, you will have to use the DNS name server. For forwarding and for the local area network (LAN), you will have to use the standard Ethernet over Ethernet protocol.
For both these purposes, you will need to configure DHCPD on your router properly. The easiest way to do this is to change the IP address or DNS name and to put an A in front of them so that they are case sensitive. For example, if you want to change the IP address, enter an A followed by the IP address followed by a colon.
Similarly, you will have to change the DNS name if you want to change the IP address. Again, put an A before the colon and enter the new IP address. For both purposes, you need to configure DHCPD correctly. For forwarding, you will have to enable forwarding for the wireless NIC. You have to check whether you are using the wired or wireless NIC and then enable the forwarding for that.
For the LAN network, it is again important to configure DHCPD. In order to do this, you have to go to ‘Networking’ and click on the option ‘Add wireless devices’. Then, you have to click on ‘Local Area Connection’ and then type in the SSID of the router you want to configure DHCPD with. Finally, you have to enter the IP address of the network you want to connect to. And that is all.
These are the basic steps required to configure DHCPD on Cisco routers. You might find other steps required to be done but this should help you get a handle on things. If you still have problems, you can ask help from either the hardware vendor or the IT support services group at your Cisco Certified Internet Exchange (Cisco IKE) provider. They will be able to provide you with a more detailed explanation on how to change your existing IP or DNS server settings to support DHCPD on your Cisco router interface.
