9. The network diagnostic system as in claim 8 , wherein a switch control module integrated as part of the control module is configured to cause the physical layer switch to commence copying and to cease copying at the first set of one or more of the plurality of links and to commence copying at the second set of one or more of the plurality of links.
10. The network diagnostic system as in claim 1 , wherein the first control module is further configured to group the plurality of links into two or more groups of links, wherein the two or more groups are comprised of a number of the plurality of links that is less than the total number of the plurality of links.
11. The network diagnostic system as in claim 10 , wherein the first control module is further configured to associate the first diagnostic module of the first pool of diagnostic modules with a first group of the plurality of links, and wherein the first diagnostic module associated with the first group is configured to substantially test only the links of the first group.
12. The network diagnostic system as in claim 1 , wherein the first control module is further configured to ascertain if a proper authorization key has been entered by a user; to ascertain that identification data corresponding to the plurality of links is within predetermined values; and to enable operation of the triggering upon ascertaining that the authorization key and identification data are proper.
13. The network diagnostic system as in claim 1 , further comprising an alarm module configured to receive statistics at least partially generated by the first network diagnostic module of the second pool of diagnostic modules; to determine whether the statistics satisfy a set of conditions associated with a first alarm, the first alarm having a priority; and to compare the priority of the first alarm and a priority of the second network diagnostic module of the second pool of diagnostic modules.
14. The network diagnostic system as in claim 1 , wherein the plurality of links comprise a physical layer switch and wherein the first control module is configured to cause the triggering of data on any physical layer switch regardless of type or manufacturer.
15. The network diagnostic system as in claim 1 , wherein the plurality of links comprise a plurality of physical layer switches interconnected to function as a single switch.
16. The network diagnostic system as in claim 15 , wherein the first pool of diagnostic modules is configured by the first control module to monitor the plurality of physical layer switches interconnected to function as a single switch.
17. The network diagnostic system as in claim 1 , wherein the network diagnostic system is associated with a Storage Area Network (SAN).
18. The network diagnostic system as in claim 1 , wherein the network diagnostic system utilizes an optical communication medium.
19. The network diagnostic system as in claim 1 , wherein the network diagnostic system utilizes an electrical communication medium.
20. A network diagnostic system implemented in hardware comprising:
