Filtering Addresses for Management Access
You create a list of up to 16 IP addresses or IP address groups that are allowed
access to the switch through the web interface, SNMP, or Telnet.
Command Usage
• The managemen t interfaces are open to all IP addresses by d efault. 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 address can be conf igured for SNMP, web and Telnet access respectively. Each
of these groups can include up to five different sets of addresse s, either individual
addresses or address ranges.
• When entering addres ses 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 overlapp ing address ranges.
• You cannot delete an i ndividual address from a specified range. You must delete
the entire range, and reenter the addresses.
• You can delete an add ress range just by specifying the start address, or by
specifying both the start address and end address.
