Filtering IP Addresses for Management Access
You can specify the client IP addresses that are allowed management access to the
switch through the web interface, SNMP, or Telnet.
Command Usage
• The management interfaces are open to all IP addresses by default. Once you add
an entry to a filter list, access to that interface is restricted to the specified
addresses.
• 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 addresses 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.
Command Attributes
• Web IP Filter – Configures IP address(es) for the web group.
