Filtering IP Addresses for Management Access
– 341 –
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.
