Predefined Port Groups
There are 3 predefined, automatically created port groups that are available for use, yet
cannot be defined in the policy file (if a group in the policy is configured with the name
of one of these predefined groups, the policy fails) -
• ALL - a group that includes all nodes in the fabric
• ALL_SWITCHES - a group that includes all switches in the fabric.
• ALL_CAS - a group that includes all HCA's in the fabric.

8.5.8.2 Defining a Topologies Policy File
In order to define a port group policy file, set the parameter 'topo_policy_file' in the opensm con-
figuration file.
topo_policy_file /etc/opensm/conf/topo_policy_file.cfg
Configuring a Topology Policy
The topologies policy file details a list of topologies. The policy file should be composed of one
or more paragraphs which define a topology
. Each paragraph should begin with the line 'topol-
ogy' and end with the line 'end-topology'.
