Usage Guidelines
•
This command enables ICMP messages relating to unreachable destinations. Unreachable networks,
hosts, protocols, and ports can all be specified.
•
Enabling host-unreachable and net-unreachable messages are not recommended as it can cause the
switch instability due to high-CPU conditions depending upon the volume of traffic required by these
messages.
•
The unreachable ICMP messages can also be enabled, disabled, and modified using the
command. See the
messages.
