Table 59. Detailed Routing IP Interface Fields
Proxy ARP
Indicates whether proxy ARP is enabled or disabled on the interface. When proxy ARP is
enabled, the interface can respond to an ARP request for a host other than itself. An interface
can act as an ARP proxy if it is aware of the destination and can route packets to the intended
host, which is on a different subnet than the host that sent the ARP request.
IP MTU
The largest IP packet size the interface can transmit, in bytes. The IP Maximum Transmission
Unit (MTU) is the maximum frame size minus the length of the Layer 2 header.
Field
Description
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
Indicates whether 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 status of this
field is Disabled, this interface will not send ICMP Destination Unreachable messages to
inform the host about the error in reaching the intended destination.
ICMP Redirects
Indicates whether the interface is allowed to send ICMP Redirect messages. 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.
