Which one of the following commands is required on an interface in order to apply an ACL as a packet filter?

  • access-class
  • ip access-group
  • ip access-list
  • <SGA group id>
Explanation & Hint:

To apply an Access Control List (ACL) as a packet filter on an interface of a network device such as a router or switch, the command used is:

ip access-group

This command is followed by the name or number of the access list and the direction of traffic to be filtered (inbound or outbound). For example:

ip access-group 101 in

This would apply the ACL numbered 101 to incoming traffic on the interface where the command is entered.
