Disable Icmp Access-List - Extreme Networks ExtremeWare Command Reference Manual

disable icmp access-list

disable icmp access-list
disable icmp access-list {slot <slot number>}
Description
Disables software forwarding of ICMP packets and enables hardware forwarding of ICMP packets at
wire speed on selected models of "i" series switches.
Syntax Description
slot number Specifies the physical location in the chassis of the module.
Default
Enabled
Usage Guidelines
Switches capable of hardware ICMP forwarding include the Summit 48si, Alpine 3804 and Alpine 3808,
and BlackDiamond modules MSM-3, G16X3, G24T3, G8Xi, 10GX3 and F48Ti. For further information
regarding specific models and ASIC part numbers, see the Release Notes.
Use this command to disable software forwarding and to enable hardware forwarding of ICMP packets.
When ICMP hardware forwarding is used, ICMP access lists are not permitted and ICMP no longer
uses ICMP filter rules.
When modules are mixed in the same chassis, the module continues to follow the configuration for the
slot. That is, those slots that are incapable of hardware forwarding continue to forward packets by the
CPU; slots capable and configured for hardware forwarding no longer use the CPU and handle the
forwarding through the hardware.
Example
The following command disables software forwarding of ICMP packets:
disable icmp access-list slot 5
