disable icmp port-unreachables

disable icmp port-unreachables {vlan name}

Description

Disables the generation of ICMP (Internet Control Message Protocol) port unreachable messages on one or all VLAN (Virtual LAN)s.

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
