Setting Description
Setting Description
Ignore Redirect
Messages
Enables the HDX system to ignore 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 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.
Generate
Destination
Unreachable
Messages
Generates a
Destination Unreachable message if a
packet cannot be delivered to its destination for reasons
other than network congestion.
