Using Authorized IP Managers

Defining Authorized Management Stations

Defining Authorized Management

Stations

■ Authorizing Single Stations: The table entry authorizes a single man-

agement station to have IP access to the switch. To use this method, just

enter the IP address of an authorized management station in the Autho-

rized Manager IP column, and leave the IP Mask set to 255.255.255.255. This

is the easiest way to use the Authorized Managers feature. (For more on

this topic, see “Configuring One Station Per Authorized Manager IP Entry”

on page 15-9.)

■ Authorizing Multiple Stations: The table entry uses the IP Mask to

authorize access to the switch from a defined group of stations. This is

useful if you want to easily authorize several stations to have access to

the switch without having to type in an entry for every station. All stations

in the group defined by the one Authorized Manager IP table entry and its

associated IP mask will have the same access level—Manager or Operator.

(For more on this topic, refer to “Configuring Multiple Stations Per

Authorized Manager IP Entry” on page 15-10.)

To configure the switch for authorized manager access, enter the appropriate

Authorized Manager IP value, specify an IP Mask, and select either Manager

or Operator for the Access Level. The IP Mask determines how the Authorized

Manager IP value is used to allow or deny access to the switch by a manage-

ment station.

Overview of IP Mask Operation

The default IP Mask is 255.255.255.255 and allows switch access only to a

station having an IP address that is identical to the Authorized Manager IP

parameter value. (“255” in an octet of the mask means that only the exact value

in the corresponding octet of the Authorized Manager IP parameter is allowed

in the IP address of an authorized management station.) However, you can

alter the mask and the Authorized Manager IP parameter to specify ranges of

authorized IP addresses. For example, a mask of 255.255.255.0 and any value

for the Authorized Manager IP parameter allows a range of 0 through 255 in

the 4th octet of the authorized IP address, which enables a block of up to 254

IP addresses for IP management access (excluding 0 for the network and 255

for broadcasts). A mask of 255.255.255.252 uses the 4th octet of a given Autho-
