Using Acl Groups - Nortel Alteon OS 42C4911 Application Manual

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, destina-
tion 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 con-
tent in the packet header, such as the source address, destination address, source port num-
ber, destination port number, and others. Packet classifiers identify flows for more
processing.
The GbESM 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 1:
VLAN = 1
SIP = 10.10.10.1 (255.255.255.0)
Action = permit
