What does this mean in a Cisco Switch Config?

We are upgrading from a 3550 to a 3750 switch, and the only thing in the config I don't understand is this.

3550
ip access-list extended CMP-NAT-ACL
 dynamic Cluster-HSRP deny   ip any any
 dynamic Cluster-NAT permit ip any any

Open in new window


If I try to enter it into the 3750 I get this error.
% Only one dynamic entry can be configured per ACL.

Open in new window

and the config is saved at this.
ip access-list extended CMP-NAT-ACL
 dynamic Cluster-HSRP deny   ip any any

Open in new window


What does this policy do?  What should it be?

So the first place I would point you to is this Cisco article on HSRP with a 3560 switch -
http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/12.2_52_se/configuration/guide/swhsrp.html

and its corresponding document for the 3750
http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_55_se/configuration/guide/swhsrp.html

Are you using HSRP?

We only have one internet connection, so I would say no to using HSRP.

Then, in my opinion, you can completely ignore this bit of the configuration unless there are other bits of the ACL you need.

But if you're not using HSRP, you can ignore the dynamic entries listed in your question.
