Usage Guidelines
Enables the generation of ICMP port unreachable messages (type 3, code 3) when a TPC or UDP request
is made to the switch, and no application is waiting for the request, or access policy denies the request.
If a VLAN is not specified, the command applies to all IP interfaces.
This command only affects the generation of certain ICMP packets. Filtering of ICMP packets usually
forwarded by the switch is controlled by the access-list commands.
