Using Authorized IP Managers
Overview

Overview

Authorized IP Manager Features 

The Authorized IP Managers feature uses IP addresses and masks to deter-
mine which stations (PCs or workstations) can access the switch through the 
network. This covers access through the following means:

–

Telnet and other terminal emulation applications

–

The switch’s web browser interface 

–

SNMP (with a correct community name)

Also, when configured in the switch, the Authorized IP Managers feature takes 
precedence over local passwords, TACACS+, RADIUS, Port-Based Access 
Control (802.1X), and Port Security. This means that the IP address of a 
networked management device must be authorized before the switch will 
attempt to authenticate the device by invoking other access security features. 
If the Authorized IP Managers feature disallows access to the device, then 
access is denied. Thus, with authorized IP managers configured, having the 
correct passwords is not sufficient for accessing the switch through the 
network unless the station attempting access is also included in the switch’s 
Authorized IP Managers configuration.

You can use Authorized IP Managers along with other access security features 
to provide a more comprehensive security fabric than if you use only one or 
two security options. Refer to table 1-1, “Management Access Security Protec-
tion” (page 1-4) for a listing of access security features with the security 
coverage they provide.
