Set Up an IP ACL with Two Rules
This section shows you how to set up an IP ACL with two rules, one applicable to TCP traffic
and one to UDP traffic. The content of the two rules is the same. TCP and UDP packets will
be accepted by the M4100 and M7100 Managed Switch only if the source and destination
stations have IP addresses within the defined sets.

CLI: Set Up an IP ACL with Two Rules
The following is an example of configuring ACL support on a 7000 Series Managed Switch.
Create ACL 101. Define the first rule: The ACL will permit packets that match the specified
source IP address (after the mask has been applied), that are carrying
TCP traffic, and that
are sent to the specified destination IP address.
1. Enter these commands:
(Netgear Switch) #config
(Netgear Switch) (Config)#access-list 101 permit tcp 192.168.77.0 0.0.0.255
192.178.77.0 0.0.0.255
