2.3. UDP Profile¶
A UDP profile is a protocol profile that controls the way BIG-IP processes UDP traffic. With DNS, custom UDP profiles are often used to set low idle times so as not to fill the connection table as DNS tends to be a lot of short lived connections.
Navigate to: DNS ›› Delivery : Profiles : Protocol : UDP
Create a UDP profile as shown in the following table. By inheriting from udp_gtm_dns profile, notice the idle timeout setting.
Setting | Value |
---|---|
Name | example.com_udp-dns_profile |
Parent Profile | udp_gtm_dns |
