Routing IP Interface Summary Fields (Continued)
Field
Description
Details
window – If you select an interface and click
Details
, the
Details
window opens and displays the following additional routing
information for the selected interface:
Routing Mode
Indicates whether routing is administratively
Enabled
or
Disabled
on the interface.
Link Speed Data Rate
The physical link data rate of the interface.
IP Address Configuration
Method
The source of the IP address, which is one of the following:
•
None
The interface does not have an IP address.
•
Manual
The IP address has been statically configured by an administrator.
•
DHCP
The IP address has been learned dynamically through DHCP. If the method is DHCP but the
interface does not have an IP address, the interface is unable to acquire an address from a network
DHCP server.
Bandwidth
The configured bandwidth on this interface. This setting communicates the speed of the interface to
higher-level protocols.
Encapsulation Type
The link layer encapsulation type for packets transmitted from the interface, which can be either
Ethernet
or
SNAP
.
Forward Net Directed
Broadcasts
Indicates how the interface handles network-directed broadcast packets. A network-directed
broadcast is a broadcast directed to a specific subnet. The possible values are as follows:
•
Enabled
Network directed broadcasts are forwarded.
•
Disabled
Network directed broadcasts are dropped.
Local Proxy ARP
Indicates whether local proxy ARP is
Enabled
or
Disabled
on the interface. When local proxy ARP is
enabled, the interface can respond to an ARP request for a host other than itself. Unlike proxy ARP,
local proxy ARP allows the interface to respond to ARP requests for a host that is on the same subnet
as the host that sent the ARP request. This feature is useful when a host is not permitted to reply to
an ARP request from another host in the same subnet, for example when using the protected ports
feature.
Destination Unreachables
Displays
Enabled
if the interface is allowed to send ICMP Destination Unreachable message to a host
if the intended destination cannot be reached for some reason. If the field displays
Disabled
, this
interface will not send ICMP Destination Unreachable messages to inform the host about the error in
reaching the intended destination.
ICMP Redirects
Displays
Enabled
if the interface is allowed to send ICMP Redirect messages; otherwise, displays
Disabled
. The device sends an ICMP Redirect message on an interface only if ICMP Redirects are
enabled both globally and on the interface. An ICMP Redirect message notifies a host when a better
route to a particular destination is available on the network segment.
Use the buttons to perform the following tasks:
• To edit an interface’s routing configuration, select the interface and click
Edit
. The display changes to
the
Routing IP Interface Configuration
page; for instructions on using this page, see
“Routing IP Interface
Configuration” on page 195
.
• To view detailed routing information on an interface, select the interface’s entry and click
Details
.
• Click
Refresh
to refresh the page with the most current data from the switch.
To retain the changes across the switch’s next power cycle, click
