Layer 3 Cpu Filter Commands - D-Link xStack DES-3528 Series Cli Reference Manual

Layer 3 CPU Filter Commands

The L3 CPU Filter commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters)
in the following table.
When the Switch receives a packet such as PIM, DVMRP or IGMP query, the L3 CPU filter mode will determine how
the packet is handled. If the mode is disabled, the packets will be sent to the CPU and will be treated according to the
RFC standards. If the mode is enabled, the packets will be discarded. That means the packets will not be sent to the
CPU and will not be propagated.

Example usage:
To display the filtering status:
DES-3528:admin#
Command: show cpu_filter l3_control_pkt ports 1:1-1:2
Parameters
<portlist> [{dvmrp | pim | igmp_query}(1) | all] state [enable | disable]
{<portlist>}
Used to discard the l3 control packets sent to CPU from specific ports.
config cpu_filter l3_control_pkt <portlist> [{dvmrp | pim | igmp_query}(1) | all] state
[enable | disable]
This command is used to discard the l3 control packets sent to CPU from specific ports.
portlist – Specifies the port list to filter control packet.
dvmrp – Speficies that the filtered L3 control protocol as DVMRP.
pim – Speficies that the filtered L3 control protocol as PIM.
igmp_query – Speficies that the filtered L3 control protocol as IGMP query.
state – Enable or disable the filtering function. Default is disable.
Only Administrator and Operator and Power-User-level users can issue this command.
config filter control_packet 1-26 dvmrp pim state enable
Used to display the l3 control packet CPU filtering status.
show cpu_filter l3_control_pkt ports {<portlist>}
This command is used to display the l3 control packet CPU filtering status.
portlist – Specifies the port list to filter control packet.
None.
show cpu_filter l3_control_pkt ports 1:1-1:2
