Access
The Access menu lets you set up IP access lists and trusted source MAC addresses.
IP Access List
The IP Access List screen lets you limit the IP addresses that can access the management portion
of the switch. The switch responds only to requests from computers with an IP address in the list,
so include your IP address and corresponding subnet mask to set this feature.
To configure your IP Access list:
1. Select Security > Access > IP Access List. A screen similar to the following one displays.
