IPv4-Based ACL
IPv4-based ACLs are used to check IPv4 packets, while other types of frames, such as ARPs, are
not checked.
The following fields can be matched:
•
IP protocol (by name for well-known protocols or directly by value)
•
Source/destination ports for TCP/UDP traffic
•
Flag values for TCP frames
•
ICMP and IGMP type and code
•
Source/destination IP addresses (including wildcards)
•
DSCP/IP-precedence value
Note
—ACLs are also used as the building elements of flow definitions for per-flow QoS handling.
The IPv4 Based ACL page enables adding ACLs to the system. The rules are defined in the IPv4
Based ACE page.
