Setting Description
Setting Description

Enables the HDX system to ignore ICMP redirect messages
from network routers. A redirect message tells the endpoint
to use a different router than the one it is using.
ICMP
Transmission
Rate Limit
(millisec)
Specifies the minimum number of milliseconds between
transmitted ICMP “error” packets. Enter a number between 0
and 60000. The default value of 1000 signifies that the
system sends 1 packet per second. If you enter 0, the
transmission rate limit is disabled.
This setting applies only to “error” ICMP packets. This
setting has no effect on “informational” ICMP packets, such
as echo requests and replies.
