NETGEAR 8800 Chassis Switch CLI Manual Usage Guidelines Enables the generation of an ICMP time exceeded message (type 11) when the TTL field expires during forwarding. IP multicast packets do not trigger ICMP time exceeded messages. 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 the generation of ICMP time exceeded messages on VLAN accounting: enable icmp time-exceeded vlan accounting enable icmp timestamp enable icmp timestamp {vlan } Description Enables the generation of an ICMP timestamp response on one or all VLANs. Syntax Description name Specifies a VLAN name. Default Enabled. Usage Guidelines Enables the generation of an ICMP timestamp response (type 14, 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. Example The following command enables the generation of an ICMP timestamp response on VLAN accounting: enable icmp timestamp vlan accounting enable icmp unreachables enable icmp unreachables {vlan } 864 | Chapter 19.

IP Unicast Commands

NETGEAR 8800 Chassis Switch CLI Manual

Usage Guidelines

Enables the generation of an ICMP time exceeded message (type 11) when the TTL field

expires during forwarding. IP multicast packets do not trigger ICMP time exceeded

messages. 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 the generation of ICMP time exceeded messages on VLAN

accounting

enable icmp time-exceeded vlan accounting

enable icmp timestamp

enable icmp timestamp {vlan <name>}

Description

Enables the generation of an ICMP timestamp response on one or all VLANs.

Syntax Description

Default

Enabled.

Usage Guidelines

Enables the generation of an ICMP timestamp response (type 14, 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.

Example

The following command enables the generation of an ICMP timestamp response on VLAN

accounting

enable icmp timestamp vlan accounting

enable icmp unreachables

enable icmp unreachables {vlan <name>}

name

Specifies a VLAN name.
