Description
Enables the generation of ICMP port unreachable messages on one or all VLANs.

name Specifies a VLAN name.

Usage Guidelines
Enables the generation of ICMP port unreachable messages (type 3, code 3) when a TCP 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.
Example
The following command enables ICMP port unreachable messages on VLAN accounting:
enable icmp port-unreachables vlan accounting
