Configuring the Switch
3-74

• When entering addresses for the same group (i.e., SNMP, web or Telnet), the
switch will not accept overlapping address ranges. When entering addresses for
different groups, the switch will accept overlapping address ranges.
• You cannot delete an individual address from a specified range. You must delete
the entire range, and reenter the addresses.
• You can delete an address range just by specifying the start address, or by
specifying both the start address and end address.
