Some access lists use more memory than others. Depending on the type of access list, the actual limit

Total Rules
1. Use the show resource rule command to view the default values for partitions other than 12.
2. Each established command creates a control and data rule, so this value is doubled in the Total Rules value.
3. This limit is lower than in release 2.3.
Rules in Multiple Context Mode
In multiple context mode with the default of 12 memory partitions, each context supports the maximum
number of rules listed in
less, depending on how many contexts you have and how many partitions you configure. See the
Memory Partitions" section on page 4-12
If you reduce the number of partitions, the maximum number of rules is recalculated and might not
match the total system number available for 12 partitions. To view the maximum number of rules for
partitions, enter the following command in the system execution space:
hostname(config)# show resource rule
For example, the following is sample output from the show resource rule command, and shows the
maximum rules as 19219 per partition with 12 partitions (this is an example only, and might differ from
the actual number of rules for your system):
hostname(config)# show resource rule
