Condition Combinations

Condition Combinations
The CLI prevents you from configuring invalid condition combinations that are never allowed; however, it
does allow you to create combinations that are supported in some scenario. For example, you might
configure source ip and and a destination ip for the same condition. This is a valid combination, but will
only be used to classify bridged traffic.
The following conditions are supported and may be combined with other conditions and/or actions:
Layer 1—source port, source port group, destination port, destination port group.
•
Layer 2—source MAC, source MAC group, destination MAC, destination MAC group, 802.1p, ether-
•
type, source VLAN, destination VLAN (multicast policies only).
Layer 3—IP protocol, source IP, source network group, destination IP, destination network group,
•
ToS, DSCP, ICMP type, ICMP code.
Layer 4—source TCP/UDP port, destination TCP/UDP port, service, service group.
•
Note the following:
Layer 2 and Layer 4 conditions cannot be combined, unless the Layer 2 condition is for 802.1p. This is
•
the only Layer 2 condition that is allowed in combination with Layer 4 conditions.
Source and destination parameters can be combined in Layer 2, Layer 3, and Layer 4 conditions.
•
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.
Layer 2 and Layer 3 rules are always effected on bridged and routed traffic. As a result, combining
•
source or destination TCP/UDP port and IP protocol in a condition is allowed.
In a given rule, ToS or DSCP may be specified for a condition with priority specified for the action.
•
Use the following policy condition combinations table as a guide when configuring policy conditions. For
more information about policy action combinations, see
