Filtering IP Addresses for Management Access
You can create a list of up to 16 IP addresses or IP address groups 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 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.
