The DHCP server allocates IP addresses to clients and records address allocation information in the DHCP log file. The logging function helps in fault location and routine maintenance. It also keeps track of address conflicts, lease renewals and releases. You can check the status of the logging function with the display ip pool name command. Once you have set up a global address pool, you can configure the logging function.
Configuring an IP address for logging
First of all, you must enable DNS on your server. Then, you can configure your security system to log traffic to a remote server. In some cases, you may need to configure more than one destination for the logging traffic. This feature is useful for redundant backup for standalone and active/backup configured chassis cluster deployments.
IP address is a special name assigned to a network adapter. It is required by network computers to communicate with each other. There are two types of IP addresses – static and dynamic.
Specifying a user, group, or user list as the packet source
If you’d like to specify a specific user, group, or user list as the source of packets for logging, you can use the -a option. It will display the user’s current group name. However, you’ll have to log out and back in again for the changes to take effect.
The name of the user or group must start with a letter, and it must be at least 8 characters long. The name must be case-sensitive, no matter what the operating system or platform. The attributes can be an array of key-value pairs. Specifying a user, group, user list, or group name will allow the system to identify the user and log the data on a specific user.
Using a static IP address
If you need to log the activity of all devices on your network, it would be beneficial to use a static IP address. Using DHCP for this 192.168.o.1 task is fine for everyday use, but when you need to perform more advanced networking tasks, using a static IP address is the best option. DHCP IP addresses are difficult to remember and expire, and static IP addresses are much easier to keep track of.
Static IP addresses can be obtained from your internet service provider. This method is easy to set up and can be very helpful for businesses that have complicated internet needs.
Using an ephemeral IP address
If you are using an ephemeral IP address to log to your database, you should be aware that it is not a permanent IP address. These addresses are temporary and will disappear as soon as they’re no longer required. This is because ephemeral IP addresses belong to the same compartment as a VNIC.
In the case of logging, an ephemeral IP address is useful in two situations. First, it allows you to keep logs more secure. You can easily manage your ephemeral IP address by setting up alerts based on the ephemeral IP address. Secondly, it is important to make sure that the IP address is not used for any other purpose. This will prevent any security issues that may arise as a result of logging to the wrong IP address.
Using a NAT-translated IP address
In order for your network to send and receive traffic, your computer needs an IP address, which is a one-to-one mapping between local and global addresses. This is known as NAT, and it is commonly used in Port Address Translation (PAT). There are two different types of NAT, one known as static NAT and the other as dynamic NAT.
Static NAT maps IPs one-to-one from private to public, while dynamic NAT draws IPs from a pool when needed. In both cases, the computer receiving the packet establishes a connection to the source port and IP address, and it doesn’t know that the IP address has been translated.
