Configuring Through View by Port
By choosing the option View access control list by Port, it is easy to
see the access permission granted for each port. This viewing option is
particularly useful for adding hosts to specific ports.
Adding a Host IP Address to a Specific Port
1. Click on the Port you would like to add the host to.
2. Click on Add IP.
3. To add access for only one computer, select a single computer,
and then enter the host’s IP address in the appropriate text box.
To add access for a group of computers, select a group of com-
puter, and then enter the IP address and netmask. (E.g., for net-
work class C computers, you might enter 192.168.1.0 for IP
address, and then 255.255.255.0 for netmask.)
