Global Routing IP Configuration
Use the Routing IP Configuration page to configure global routing settings on the device. Routing pro-
vides a means of transmitting IP packets between subnets on the network. Routing configuration is
necessary only if the device is used as a Layer 3 device that routes packets between subnets. If the
device is used as a Layer 2 device that handles switching only, it typically connects to an external
Layer 3 device that handles the routing functions; therefore, routing configuration is not required on the
Layer 2 device.
To display the Routing IP Configuration page, click

in the navigation pane
and click the

tab.

Field
Description
Routing Mode
The administrative mode of routing on the device. The options are as follows:
Enable
– The device can act as a Layer 3 device by routing packets between interfaces
configured for IP routing.
Disable
– The device acts as a Layer 2 bridge and switches traffic between interfaces.
The device does not perform any internetwork routing.
ICMP Echo Replies
Select
Enable
or
Disable
from the drop-down menu. If you select
Enable
, then only the
router can send ECHO replies. By default, ICMP Echo Replies are sent for echo requests.
ICMP Redirects
Select this option to allow the device to send ICMP Redirect messages to hosts. An ICMP
Redirect message notifies a host when a better route to a particular destination is available
on the network segment.
ICMP Rate Limit Interval
To control the ICMP error packets, you can specify the number of ICMP error packets that are
allowed per burst interval. By default, the rate limit is 100 packets per second, i.e. the burst
interval is 1000 milliseconds. To disable ICMP rate limiting, set this field to zero. The valid rate
interval range is 0 to 2147483647 milliseconds.
ICMP Rate Limit Burst Size
To control the ICMP error packets, you can specify the number of ICMP error packets that are
allowed per burst interval. By default, the burst size is 100 packets. When the burst interval
is zero, then configuring this field is not a valid option. The valid burst size range is 1 to 200.
