Routing IP Configuration
Use the Routing IP Configuration page to configure global routing settings on the device. Routing
provides 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.

Table 265: Configuration Fields
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,
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; that is, the burst interval is 1000 milliseconds. To disable
ICMP rate limiting, set this field to 0. The valid 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.
Static Route Preference
The default distance (preference) for static routes. Lower route-distance values
are preferred when determining the best route. The value configured for Static
Route Preference is used when using the CLI to configure a static route and no
preference is specified. Changing the Static Route Preference does not update
the preference of existing static routes.
Local Route Preference
The default distance (preference) for local routes.
Maximum Next Hops
The maximum number of hops supported by the switch. This is a read-only
value.
