Defining IP Based 

ACLs

Access Control Lists (ACL) allow network managers to define 

classification actions and rules for specific ingress ports. Your switch 

supports up to 256 ACLs. Packets entering an ingress port, with an active 

ACL, are either admitted or denied entry. ACLs are composed of access 

control entries (ACEs) that are made of the filters that determine traffic 

classifications. The total number of ACEs that can be defined in all ACLs 

together is 256. 

Monitor users have no access to this page.

Device > ACL > IP Based ACL > Setup
