Refuse IP table. The table is used to configure the address segment (under a specified protocol) with which the user cannot access the device. This can prevent the invalid users from logging in to the device. After address segment is configured in the table, the operators with the IP addresses in the address segment cannot access the device. The indexes of this table are hwFirewallProtocolType and hwRefuseIpStartAddr. For the hwFirewallProtocolType object, refer to hwFirewallSwitchTable. hwRefuseIpTable is used for configuring a list of prohibited IP addresses. The IP address list takes effect only when the protocol corresponding to hwFirewallSwitchTable is enabled.
