Differences between CSM and ACE

clarkmat — Mon, 22 Jan 2007 09:58:11 GMT

Could someone give me a short answer on the differences betwenn CSM and ACE? For example if you configured an ACE in a DMZ can you still configure VIP with vserver command? Are the configurations similar? I know that the policy configuration is different but also wondered where you add the sticky feature config?

Thanks

they use different CLI.

But you can achieve with the ACE module everything you could with the CSM.

However, ACE is the brain new module and comes with extra new features and will receive even more in the future.

thanks Gilles

As the CLI is different will there be examples posted? I mean adding for example sticky configuration on the vserver is now added where exactly on ACE?

the documentation is online and examples will be posted once we collect information about what is most needed.

For stickyness, you configure the sticky group more or less like a CSM.

One difference is that you need to associate the sticky group to a serverfarm

You then go into your policy-map and instead of using a serverfarm you use a sticky-serverfarm which is the group you just created.

Very simply.

switch/Admin(config)# sticky ip-netmask 255.255.255.0 address source ?

Enter the sticky group name (Max Size - 64)

switch/Admin(config-sticky-ip)# serverfarm lin

switch/Admin(config)# policy-map type loadbalance first-match L1-STICKY

switch/Admin(config-pmap-lb)# class class-default

switch/Admin(config-pmap-lb-c)# sticky-serverfarm ?

Enter sticky group name (Max Size - 64)

IPSTICKY

switch/Admin(config-pmap-lb-c)# sticky-serverfarm
