Filtering IP Addresses for Management Access
– 355 –
IP address can be configured for SNMP, web and Telnet access respectively.
Each of these groups can include up to five different sets of addresses, either
individual addresses or address ranges.
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.
