Application Mapping Priorities

If incoming flow matches the combination of criteria that are specified in an application mapping rule, the flow is mapped to the rule destination port. If rules conflict, the following priorities apply. A rule takes precedence when its criteria are ranked higher than the criteria of another rule.

• Priority 1: Host rule with Host, Protocol, Port, and ToS specified
• Priority 2: Host rule with Host, Protocol, and Port specified, but with the ToS set to ALL
• Priority 3: All (ToS) rule with ToS specified
• Priority 4: Host rule with the Host specified, but with the Protocol and ToS set to ALL
• Priority 5: Subnet rule
• Priority 6: NBAR2 rule
