TR0153 Rev. E1 141
To limit the range of addresses for ARP requests that the gateway will respond to, set the
‘l2.hide_internal.enable’ parameter in the ‘sys’ interface to ‘yes’. Set the
‘l2.hide_internal.gateway.deny.mesh’ in the ‘sys’ interface to ‘yes’ to disregard ARP requests
for IP addresses within the mesh subnet (typically 172.29.0.0/16). Set
‘l2.hide_internal.gateway.deny.all’ in the ‘sys’ interface to ‘yes’ to disregard all ARP requests
(except for addresses within the client address space if centralized DHCP server mode is
enabled).
The example below shows how to disregard all ARP requests except for those for addresses
within the client address space.
> use sys
sys> set l2.hide_internal.enable=yes
sys> set l2.hide_internal.gateway.deny.all=yes

address space.

sys> set l2.hide_internal.deny.all=no
Web GUI
The state of layer 2 emulation is set on the “System” tab of the “System” page (see Figure 63).
The console interface in the web GUI must be used to configure which address ranges the
gateway responds to ARP requests for. See the CLI section above for parameter names and
set these using the console interface (see section 8.15).
