Using ACL Filters
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.
BLADEOS 6.5 supports up to 127 ACLs when the switch is operating in the Balanced deployment
mode (see
“Deployment Profiles” on page 147 ). ACL menus and commands are not available in the
Routing deployment mode.
The G8124 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 75 .
