FWSM 4.1(1) and access-list commit.

How can I commit access-list more quickly?

When I add an ACE the FWSM takes more times to commit.

Thanks.

Regards.

Re: FWSM 4.1(1) and access-list commit.

To add to Kureli's suggestions, you have about 10K rules. Unfortunately in order to test a new rule, all of them need to be recompiled. And with 10K rules it will take some time to recompile (1-2mins is normal). Note if you have ACL optimization enabled that will take a more time. You will not be losing traffic during that time, though, you really need to wait for the ACL to be complied to take effect and test them.

I hope it clarifies it a little.

Re: FWSM 4.1(1) and access-list commit.

You do have auto commit right not manual commit? ACL compilation will take a few seconds. How long does it take? What is the ACE count?

sh access-list | i elements

sh resource acl (from the system space)

This command will provide information about the context allocated to the partition and the maximum number of ACE used
in each partition. 

sh np 3 acl count (from the context in question)

You can also read the doc on FWSM acl limit that I published here: https://supportforums.cisco.com/docs/DOC-8786

Re: FWSM 4.1(1) and access-list commit.

Many thanks for your help.

We are using single mode, auto commit and ASDM to change configuration.

ACL compilation takes more than two minutes and is very very tedious.

We need to wait some minutes to make a test of new added ACE!

Re: FWSM 4.1(1) and access-list commit.

Could you pls. try to add a dummy ace to an existing acl via CLI and tell me how long it takes to compile?

example.

conf t

access-list BrennerCom_access_in line 1 per icmp any any

You can remove it later.

Done.

FWSM takes one minute and 40 seconds to compile it.

Thanks.
