ExtremeWare XOS 10.1 Command Reference Guide 465

enable icmp port-unreachables

enable icmp port-unreachables {vlan <name>}

Description

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

Syntax Description

Default

Enabled.

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.

Example

The following command enables ICMP port unreachable messages on VLAN accounting:

enable icmp port-unreachables vlan accounting

name Specifies a VLAN name.
