netMgmtIpSubnetMask

The switch's administrative IP subnet mask.  The
switch may automatically discover a value for this object
using the BootStrap protocol (BOOTP).  The object value is
also duplicated in the MIB-II ipAddrTable.
          
The following applies to switches operating with
firmware version smaller than 6.00:
          
    When VLANs are present, The switch may be configured
    with up to 4 administrative IP subnet masks, one per VLAN.
    This object, in this case, configures the subnet mask
    for the first VLAN.  See the object vlanTable for
    how to configure the other subnet masks.
          
    Assigning multiple VLAN subnet masks is only necessary
    if the VLANs in use represent separate physical IP subnets.
          
A write to this value will take effect immediately.  The
default value is 0.0.0.0, or no subnet mask.
