Description: The switch's Snmp Community IP Mask Client IP Mask - This attribute is a mask to be logical-ANDed with the requesting entity's IP address before comparison with the Client IP Address. If the result matches with Client IP Address then the address is an authenticated IP address. For example, if the Client IP Address is 9.47.128.0 and the corresponding Client IP Mask is 255.255.255.0, a range of incoming IP addresses would match, that is, the incoming IP addresses could be a value in the following range: 9.47.128.0 to 9.47.128.255. To have a specific IP address be the only authenticated IP address, set the Client IP Address to the required IP address and set the Client IP Mask to 255.255.255.255.
