Description
Use the
system-guard l3err enable
command to enable Layer 3 error control.
Use the
undo system-guard l3err enable
command to disable Layer 3 error control.
By default, this feature is enabled.
The Layer 3 error control feature determines how the switch disposes of Layer packets which the switch
considers to be error packets:
With the Layer 3 error control feature disabled, the switch delivers all Layer 3 packets which the switch
considers to be error packets (including IP packets with the options field) to the CPU for further
processing;
With the Layer 3 error control feature enabled, the switch directly discards all Layer 3 packets which the
switch considers to be error packets without delivering them to the CPU.
In normal situations, we recommend that you enable this feature. Because the switch cannot forward
error packets and IP packets with the Options field set, delivering all these packets to the CPU will affect
the normal work of the CPU.
Examples
