Parameter
None
Description
Use the ip icmp-time-exceed enable command to enable the switch to send the
ICMP message "time exceeded" to the network management system when the
switch receives an IP packet whose TTL is less than or equal to 1, thus preventing
the switch from keeping sending unreachable packets to the sending end.
Use the undo ip icmp-time-exceed enable command to remove the
configuration. As a result, the switch sends an unreachable packet to the sending
end.
By default, the switch sends the ICMP message "time exceeded" to the network
management system
Example
# Configure that the switch sends the ICMP message "time exceeded" to the
network management system when the switch receives an IP packet whose TTL is
less than or equal to 1.
