| name | Specifies a VLAN name. |
Enabled.
Enables the generation of an ICMP timestamp response (type 3, code 0) when an ICMP timestamp request is received. 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.
The following example enables the generation of ICMP unreachable messages on all VLANs:
enable icmp unreachables
