Using ACL Filters

Summary of ACL Actions

© Copyright IBM Corp. 2011
Access Control Lists (ACLs) are filters that allow you to classify and segment traffic,
so you can provide different levels of service to different traffic types. Each filter
defines the conditions that must match for inclusion in the filter, and also the actions
that are performed when a match is made.
IBM Networking OS 6.8 supports up to 512 ACLs.
The G8000 allows you to classify packets based on various parameters. For
example:
• Ethernet: source MAC, destination MAC, VLAN number/mask, Ethernet type,
priority.
• IPv4: Source IP address/mask, destination address/mask, type of service, IP
protocol number.
• TCP/UPD: Source port, destination port, TCP flag.
• Packet format
For ACL details, see "Access Control Lists" on page
Actions determine how the traffic is treated. The G8000 QoS actions include the
following:
• Pass or Drop
• Re-mark a new DiffServ Code Point (DSCP)
• Re-mark the 802.1p field
• Set the COS queue
79.
