Using ACL Groups
Access Control Lists (ACLs) allow you to classify packets according to a particular content in the packet
header, such as the source address, destination address, source port number, destination port number,
and others. Packet classifiers identify flows for more processing.
You can define a traffic profile by compiling a number of ACLs into an ACL Group, and assigning the
ACL Group to a port.
ACL Groups are assigned and enabled on a per-port basis. Each ACL can be used by itself or in
combination with other ACLs or ACL Groups on a given switch port.
ACLs can be grouped in the following manner:
• Access Control Lists
Access Control Lists (ACLs) allow you to classify packets according to a particular content in the
packet header, such as the source address, destination address, source port number, destination port
number, and others. Packet classifiers identify flows for more processing.
The HP 10GbE switch supports up to 384 ACLs. Each ACL defines one filter rule. Each filter rule is a
collection of matching criteria, and can include an action (permit or deny the packet). For example:
ACL 200:
VLAN = 1
SIP = 10.10.10.1 (255.255.255.0)
Action = permit
• Access Control Groups
An Access Control Group (ACL Group) is a collection of ACLs. For example:
ACL Group 1
ACL 382:
VLAN = 1
SIP = 10.10.10.1 (255.255.255.0)
Action = permit
ACL 383:
VLAN = 2
SIP = 10.10.10.2 (255.255.255.0)
Action = deny
ACL 384:
PRI = 7
DIP = 10.10.10.3 (255.255.0.0)
Action = permit
In the example above, each ACL defines a filter rule. ACL 383 has a higher precedence than
ACL 382, based on its number.
Use ACL Groups to create a traffic profile by gathering ACLs into an ACL Group, and assigning the
ACL Group to a port. The HP 10GbE switch supports up to 384 ACL Groups. Each ACL group
supports up to 96 ACLs.
