Description
Disables the generation of ICMP port unreachable messages on one or all VLANs.
Syntax Description
name | Specifies a VLAN name. |
Default
Enabled.
Usage Guidelines
Disables 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 an 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 example disables ICMP port unreachable messages on VLAN "accounting":
disable icmp port-unreachables vlan accounting
