You can use the MIRRORING parameter to copy the offending traffic to a
destination port mirror for analysis with a data analyzer. To define the
destination port, refer to “SET SWITCH MIRROR” on page 228.
Caution
This defense is extremely CPU intensive and should be used with
caution. Unrestricted use can cause a switch to halt operations if the
CPU becomes overwhelmed with IP traffic. To prevent this, Allied
Telesis recommends that you activate this defense on only one port
at a time and where ingress fragments comprise only a small
percentage of the port’s total traffic.
Example
The following command activates the defense on port 22:
set dos teardrop port=22 state=enable
