A CNAME record specifies that a domain name is an alias of another domain. When you create a pool with a canonical name, BIG-IP Global Traffic Manager(GTM) responds to DNS name resolution requests for the CNAME with the real fully qualified domain name (FQDN).

1. On the Main tab, click DNS > GSLB > Pools. The Pools list screen opens.
2. Click Create.
3. In the Name field, type a name for the pool. Names must begin with a letter, and can contain only letters, numbers, and the underscore (_) character.
   Important: The pool name is limited to 63 characters.
4. From the Configuration list, select Advanced.
5. In the CNAME field, type the canonical name of the zone to which you want GTM to send DNS queries.
   Tip: When you provide a canonical name, you do not add members to the pool, because the CNAME record always takes precedence over pool members. Additionally, a pool with a CNAME is not monitored for availability.
6. Click Finished.

1. On the Main tab, click DNS > GSLB > Wide IPs. The Wide IP List screen opens.
2. Click Create. The New Wide IP screen opens.
3. In the Name field, type a name for the wide IP.
   Tip: You can use two different wildcard characters in the wide IP name: asterisk (*) to represent several characters and question mark (?) to represent a single character. This reduces the number of aliases you have to add to the configuration.
4. From the Pool list, select the CNAME pool, and then click Add.
5. Click Finished.

1. On the Main tab, click Statistics > Module Statistics > DNS > GSLB. The Global Traffic statistics screen opens.
2. From the Statistics Type list, select Wide IPs. Information displays about the cumulative number of DNS name resolution requests processed by the wide IP, and the number of requests load balanced using specific methods.
