About using authorized IP Managers

The Authorized IP Managers feature uses IP addresses and masks to determine 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 WebAgent –

  • SSH

  • SNMP versions 1, 2 and 3(with a correct community name)

  • TFTP

Also, when configured in the switch, the Authorized IP Managers feature takes precedence over local passwords, TACACS+, and RADIUS. 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 any 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.


When no Authorized IP manager rules are configured, the access method feature is disabled, that is, access is not denied.
