Manage access control

Access control allows you to control which devices can access the switch over a web
browser for management purposes. By default, access control is disabled. By adding
one or more devices to the Access Control table, access control is enabled and only
devices in the table are allowed to access the switch over a web browser.
For more information, see the following sections:
• Add devices to the Access Control table on page 39
• Remove devices from the Access Control table on page 40

Add devices to the Access Control table

If you add devices to the he Access Control table, use the mask to allow one IP address
or a range of IP addresses to access the local browser interface of the switch. Consider
the following examples:
• If the mask is 255.255.255.255, only the device for which you specify the host IP
address in the Source IP Address field can access the local browser interface.
• If the host IP address in the Source IP Address field is 192.168.100.x (in which x can
be any number from 0 to 255) and the mask is 255.255.255.0, any device in the
range from 192.168.100.0 to 192.168.100.255 can access the local browser interface.
• If the host IP address in the Source IP Address field is 192.168.100.y (in which y can
be any number from 0 to 7) and the mask is 255.255.255.248, any device in the
range from 192.168.100.0 to 192.168.100.7 can access the local browser interface.
CAUTION: Add the IP address and subnet mask for the device from which you are
accessing the switch to the Access Control table before you add any other devices to
the table. Otherwise, you are locked out from the local browser interface of the switch.
To add devices to the Access Control table:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired network connection, or connect directly to a switch that
is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the switch using a web
browser on page 7.
