Management access profiles and rules
Access control allows you to configure an access control profile and set rules for access
to the device UI, access by SNMP stations, and client access to a TFTP server. We refer
to an access control profile as an access profile. You can add a single access profile,
which you can configure, activate, or deactivate.
CAUTION: If you configure a security access profile incorrectly and you activate the
access profile, you might no longer be able to access the switch’s device UI. If that
situation occurs, you must reset the switch to factory default settings (see Reset the
switch to the factory default settings on page 738).
Add an access profile
You can set up a single security access profile with which you can associate an access
rule configuration.
To add an access profile:
1. Launch a web browser.
2.
In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. Click the Main UI Login button.
The main UI login page displays in a new tab.
