HP procurve switch 2600 series Access Security Manual page 227

The above example shows an Authorized IP Manager List that allows stations
to access the switch as shown below:
IP Mask Authorized Station IP Address:
255.255.255.252 10.28.227.100 through 103
255.255.255.254 10.28.227.104 through 105
255.255.255.255 10.28.227.125
255.255.255.0 10.28.227.0 through 255
Configuring IP Authorized Managers for the Switch
Syntax: ip authorized-managers < ip address >
Configures one or more authorized IP addresses.
[mask < mask-bits >]
Configures the IP mask for < ip address >
< operator | manager >
Configures the privilege level for < ip address >.
To Authorize Manager Access. This command authorizes manager-level
access for any station having an IP address of 10.28.227.0 through
10.28.227.255:
HPswitch(config)# ip authorized-managers 10.28.227.101
mask 255.255.255.0 manager
Similarly, the next command authorizes manager-level access for any station
having an IP address of 10.28.227.101 through 103:
HPswitch(config)# ip authorized-managers 10.28.227.101
mask 255.255.255.252 manager
If you omit the mask when adding a new authorized manager, the switch
automatically uses 255.255.255.255 for the mask. If you do not specify either
Manager or Operator access, the switch automatically assigns the Manager
access. For example:
HPswitch(config)# ip authorized-managers 10.28.227.105
