15 ACL
Expanding network scale and mounting flow strengthen the position of network
security control and bandwidth allocation. Packet filtering prevents illegal users from
accessing, control flow and saves network resources. ACL (Access Control List)
filters packets by configuring the message matching rules and processing methods.
The switch port receiving messages analyzes the field according to the current ACL
rules. Once a specific message is identified, it will be allowed or forbidden to flow
through according to predetermined policies.
The packet matching rules defined by ACL can also be referenced by other functions
requiring flow distinction such as the definition of QoS flow classification rules.
ACL can filter packets by setting matching rules and processing methods. ACL is a
collection of permission and denial conditions applicable to packets. When the
interface receives the packets, the switch compares the fields and ACL to determine
the permitted and denied packets subject to specified standards. ACL classifies
packets by matching conditions, which can be the source/destination MAC address,
source/destination IP address, port No. and so on. ACL classifies packets by matching
conditions, which can be the source/destination address, port No., etc. ACL can be
divided into the following categories according to application purposes:
Basic IP ACL formulates rules based only on the source IP address of packets. ACL ID
ranges from 100 to 999. Advanced IP ACL prepares rules according to packets’
source/destination IP address, protocol types carried by
IP, and Layer 3 or 4 info such as protocol characteristics. ACL ID ranges from 100 to
999.
L2 ACL: Rules are made according to the packets’ source/destination MAC address,
802.1p priority, and L2 info such as protocol type. ACL ID ranges from 1 to 99.
