Filter Commands (Dhcp Server/Netbios); Dhcp Server Screening Settings; Netbios Filtering Setting - D-Link DAS-3636 Cli Reference Manual

DHCP Server Screening Settings

This function allows you not only to restrict all DHCP Server packets but also to receive any specified DHCP server packets by
any specified DHCP client, it is useful when one or more than one DHCP servers are present on the network and both provide
DHCP services to different distinct groups of clients. Enabling the DHCP filter for the first time will create both an access profile
and access rule per port, following this other access rules can be created. These rules are used to block all DHCP server packets.
Similarly, the addition of a permit DHCP entry will create one access profile and one access rule the first time the DHCP client
MAC address is the client MAC address, and the Source IP address is the same as the DHCP server's IP address (UDP port
number 67). These rules are used to permit the DHCP server packets with specific fileds, which the user configures.
When the DHCP Server filter function is enabled, all DHCP Server packets will be filtered from a specific port. Also, you are
allowed to create entries for specific port-based Server IP address and Client MAC address binding entries. Be aware that the
DHCP Server filter function must be enabled first. Once all settings are complete, all DHCP Server packets will be filtered from a
specific port except those that meet the Server IP Address and Client MAC Address binding.

NetBIOS Filtering Setting

When the NetBIOS filter is enabled, all NetBIOS packets will be filtered from the specified port. Enabling the NetBIOS filter
will create one access profile and create three access rules per port (UDP port numbers 137 and 138 and TCP port number 139).
For Extensive NetBIOS Filter, when it is enabled, all NetBIOS packets over 802.3 frames will be filtered from the specified port.
This command is used to configure the state of the NetBIOS filter. Enabling the Extensive NetBIOS filter will create one access
profile and create one access rule per port (DSAP (Destination Service Access Point) =F0, and SASP (Source Service Access
Point) =F0).
The DHCP Server/NetBIOS Filter commands in the Command Line Interface (CLI) are listed (along with the appropriate
parameters) in the following table.
Command
config filter dhcp_server
show filter dhcp_server
config filter netbios
show filter netbios
config filter extensive_netbios
show filter extensive_netbios
Each command is listed, in detail, in the following sections.
