    Field Description
    *Wide IP Name Enter the WideIP Name in the FQDN format.
    *Type

    Select the pool/WideIP type. The types are:

    • A - the pool/Wide IP responds to A queries. The A pool/Wide IP is a mapping of an FQDN to a set of IPv4 virtual servers that host the domain's content, such as a Web site or an e-commerce site. You can also specify pool members' virtual server and ratio settings.

    • CNAME - the pool/Wide IP responds to CNAME queries. A CNAME pool/Wide IP is a mapping of a FQDN to its canonical name. This is the configuration of a static name or a Wide IP name. Static names support older configurations. Wide IP names allow service checking, enhanced load balancing, and CNAME chasing in the reply. You can also specify pool members' ratio.

    *Load Balancing Method

    The load balancing method is used to select a pool in this WideIP. The methods are:

    • round-robin - the system selects the pools sequentially.

    • global-availability -. the system selects a pool by following the order of the Pool List. The system repeatedly selects the first pool in the list for as long as its status is available. If the pool becomes unavailable for any reason, the system then repeatedly selects the next pool in the list, and so on.

    • ratio - the system selects a pool based on the ratio that you assign to the pool.
    *Persistence By default, this option is disabled. When enabled, a local DNS makes repetitive requests on behalf of a client, the system reconnects the client to the same resource as previous requests.
    *Pool Name Name of the pool.
