Reallocating Rules Between Features
You can reallocate rules from one feature to another feature.
In multiple context mode, you can also set the rule allocation per partition, which overrides the global
Note
setting in this section. See the

Detailed Steps
To reallocate rules, perform the following steps:
Step 1
To view the total number of rules available, the default values, current rule allocation, and the absolute
maximum number of rules you can allocate per feature, enter the following command:
hostname(config)# show resource rule
For multiple context mode, enter this command in the system execution space. It shows the number of
rules per partition. See the
partitions.
For example, the following is sample output from the show resource rule command, and shows the
maximum rules as 124923 in single mode (this is an example only, and might differ from the actual
number of rules for your system):
hostname(config)# show resource rule

The target partition and rule allocation settings must be carefully calculated, planned, and preferably
tested in a non-production environment prior to making the change to ensure that all existing
contexts and rules can be accommodated.
When failover is used, both FWSMs need to be reloaded at the same time after making partition
changes. Reloading both FWSMs causes an outage with no possibility for a zero-downtime reload.
At no time should two FWSMs with a mismatched number of partitions or rule limits synchronize
over failover.
