Chapter 1 What’s New for FortiOS 5.2.1 : Firewall : Object UUID Support
  
Object UUID Support
 
UUID is only supported on large-partition platforms (>=128M).
A Universally Unique Identified (UUID) attribute has been added to some firewall objects, including virtual IPs and virtual IP groups for IPv4, IPv6, NAT46, and NAT64, so that the logs can record these UUID to be used by a FortiManager or FortiAnalyzer unit.
The UUID of an object can either be generated automatically or assigned through the CLI. To view the UUID for these objects in a FortiGate unit's logs, log-uuid must be set to extended mode, rather than policy-only, which only shows the policy UUID in a traffic log.
Syntax
config sys global
set log-uuid {disable | policy-only | extended}
end
 
config firewall {policy | policy6 | policy46 | policy64 | address| addres6 | addgrp | addgrp6}
edit <1>
set uuid <8289ef80-f879-51e2-20dd-fa62c5c51f44>
end
end
