Access Control Lists (ACLs) for the Series 5300xl Switches
Configuring and Assigning an ACL
always functions when the switch uses an ACL to filter packets. (You
cannot delete the implicit “deny any”, but you can supersede it with a
“permit any” statement.)
Standard ACL Structure
Individual ACEs in a standard ACL include only a permit/deny “type” state
ment, the source IP addressing, and an optional
log
command (available with
“deny” statements).
