DHCP Snooping

I am setting up DHCP Snooping and I am looking at the configuration guide for the 6500 series switch. These are the steps that they show:


Step 1

Add DHCP snooping to the VACL.

set security acl ip acl_name permit dhcp-snooping


Step 2

Configure the VACL to allow DHCP snooping from all hosts.

set security acl ip acl_name permit ip any any


Step 3

Save the VACL.

commit security acl acl_name


Step 4

Add an ACL to a VLAN.

set security acl map acl_name 10


What I want to know is if I make this access list will the other "set security acl" entries that I already have be overwritten? Also, for the "ip permit any any", this will make it so that all the hosts are are bound by dhcp-snoop right?

Since the named access-list used for snooping and security will be different, it will not be overwritten.


Access-list are not overwritten when you add statements but they just get appended at the end. You need to be careful while removing statements.


HTH, rate if it does
