Description

Syntax Description

Enabled.
Usage Guidelines
Disables 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 disables ICMP port unreachable messages on VLAN accounting:
disable icmp port-unreachables vlan accounting
