cpu-traffic direction match cust-filter

Use this command to configure a custom filter. The statistics and/or traces for configured filters are obtained for the packet matching configured data at the specific offset. If the mask is not specified, the default mask is 0xFF.

You can specify three different offsets specified as match conditions. Each time a custom filter is configured, the switch overrides the previous configuration.

Note

Note

The offset should consider the VLAN tag headers because the packet to the CPU is always a tagged packet.
Default None
Format cpu-traffic direction {tx|rx|both} match cust-filter offset1 data1 [mask mask1] offset2 data2 [mask mask2] offset3 data3 [mask mask3]
Mode Global Config
Parameter Description
