DESCRIPTION

EXAMPLES

       Displays the global settings for the DNS caches on the BIG-IP system.

OPTIONS
       cache-maximum-ttl
	    Specifies the number of seconds after which you want the BIG-IP system to re-query for resource records. This setting
	    allows the BIG-IP system to re-query for resource records sooner than the owner of the records intended.

       cache-minimum-ttl
	    Specifies the minimum number of seconds you want the BIG-IP system to cache DNS resource records. This setting allows
	    the BIG-IP system to cache resource records longer than the owner of the records intended.

       glob Displays the items that match the glob expression. See help glob for a description of glob expression syntax.

       regex
	    Displays the items that match the regular expression. The regular expression must be preceded by an at sign (@[regular
	    expression]) to indicate that the identifier is a regular expression. See help regex for a description of regular
	    expression syntax.

       resolver-edns-buffer-size [integer]
	    Specifies the number of bytes you want the BIG-IP system to advertise as the EDNS buffer size in UDP queries.
