Filtering IP Addresses for Management Access
• If anyone tries to access a management interface on the switch from an invalid address, the
switch will reject the connection, enter an event message in the system log, and send a trap
message to the trap manager.
• 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.
