ACL Overview
Access Control Lists (ACLs) are a collection of permit and deny conditions,
called rules, that provide security by blocking unauthorized users and
allowing authorized users to access specific resources.
ACLs can also provide traffic flow control, restrict contents of routing
updates, and decide which types of traffic are forwarded or blocked. ACLs can
reside in a firewall router, a router connecting two internal networks, or a
Layer 3 switch, such as a PowerConnect 8000-series and 8100-series switches.
You can also create an ACL that limits access to the management interfaces
based on the connection method (for example, Telnet or HTTP) and/or the
source IP address.
The PowerConnect 8000-series and 8100-series switches support ACL
configuration in both the ingress and egress direction. Egress ACLs provide
the capability to implement security rules on the egress flows (traffic leaving a
port) rather than the ingress flows (traffic entering a port). Ingress and egress
ACLs can be applied to any physical port, port-channel (LAG), or VLAN
routing port.
