Configuring QoS Condition/Action Combinations
OmniSwitch 6600 Family Network Configuration Guide April 2006 page 24-7
Condition/Action Combinations
Conditions and actions are combined in policy rules. The CLI prevents you from configuring invalid
condition/action combinations that are never allowed; however, it does allow you to create combinations
that are supported in some scenario. For example, a destination MAC address condition may be combined
with an action specifying priority for flows that are bridged only.
Note the following:
• Layer 2 and Layer 3/4 conditions cannot be combined.
• Source and destination parameters cannot be combined in Layer 2 conditions; source and destination
parameters may be combined in Layer 3/4 conditions when the qos classifyl3 bridged command is
enabled.
• Individual items and their corresponding groups cannot be combined in the same condition. For exam-
ple, a source IP address cannot be included in a condition with a source IP network group.
• Source or destination TCP/UDP port and IP protocol may be combined in the condition if bridged traf-
fic is classified as Layer 3.
• In a given rule, ToS or DSCP may be specified for a condition with priority specified for the action. No
additional action parameters are allowed.
Use the policy condition/action combinations table as a guide when creating policy rules.
How to Use the Condition/Action Combination Table. Each row represents a policy condition or condi-
tions that may be combined with a policy action or actions in the same row. Note that the table does not
represent every possible condition combination. Use the Policy Condition Combinations table on page
24-6 to cross-reference supported policy conditions.
For more information about policy condition combinations, see “Condition Combinations” on page 24-6.
