authorized to pass through an interface
•
QoS lists

Access control lists
You can use access control lists to control which packets are authorized to pass through an interface.
When a packet matches a rule on the access control list, the rule specifies whether the G350:
•
Accepts the packet or drops the packet
•
Sends an ICMP error reply if it drops the packet
•
Sends an SNMP trap if it drops the packet
Access lists have the following parts:
•
Global rules — a set of rules that are executed before the list is evaluated
•
Rule list — a list of filtering rules and actions for the G350 to take when a packet matches the
rule. Match actions on this list are pointers to the composite operation table.
