Saving Rules - Alcatel OmniSwitch 6624 Network Configuration Manual

Creating Policies
Layer 3 Rules With Compatible Actions
More than one rule may have the same condition. For example, two Layer 3 rules may have the same IP
address condition but different actions. If the actions are compatible, both rules will be applied to the flow,
regardless of the precedence settings. In this example, the rules are created with the default precedence (0)
value.
-> policy condition X source ip 10.10.2.3
-> policy action Y priority 7
-> policy action Z maximum bandwidth 10m
-> policy rule Rule1 condition X action Y
-> policy rule Rule2 condition X action Z
In this example, when a flow comes into the switch and matches source IP address 10.10.2.3, the switch
will apply both policies (Rule1 and Rule2) to the flow. On the OmniSwitch 6624/6648, a source IP
address may be combined with priority and maximum bandwidth actions at the same time, so both rules
are used.
Note. See "Condition/Action Combinations" on page 21-7
action combinations.
Layer 3 Rules With Conflicting Actions
If the actions are in conflict, however, the switch will apply only the rule with the highest precedence. For
example:
-> policy condition X source ip 10.10.2.3
-> policy action W 802.1p 5
-> policy action Z maximum bandwidth 10m
-> policy rule Rule1 condition X action W
-> policy rule Rule2 condition X action Z
In this case, a source IP address condition may be combined with an 802.1p action or a maximum band-
width action but not both at the same time (see
these actions are in conflict, the rule with the highest precedence will be applied instead. In this case, both
rules have the same precedence value (the default, since no precedence is specifically configured). The
rule that was configured first (Rule1) is considered to have the highest precedence and will be used for the
flow.

Saving Rules

The save option marks the policy rule so that the rule will be captured in an ASCII text file (using the
configuration snapshot
command or copy running-config working
If the save option is removed from a rule, the qos apply command may activate the rule for the current
session, but the rule will not be saved over a reboot. Typically, the no save option is used for temporary
policies that you do not want saved in the switch configuration file.
