Routing IP Interface Configuration Fields (Continued)
Description
The administrative mode of the interface. If set to Disable, the interface cannot forward traffic.
The state of the interface, which is either Active or Inactive. An interface is considered active if the link
is up, and the interface is in a forwarding state.
The physical link data rate of the interface.
The method to use for configuring an IP address on the interface, which can be one of the following:
• None No address is to be configured.
• Manual The address is to be statically configured. When this option is selected you can specify
the IP address and subnet mask in the available fields.
• DHCP The interface will attempt to acquire an IP address from a network DHCP server.
The IP address of the interface. This field can be configured only when the selected IP Address
Configuration Method is Manual. If the method is DHCP, the interface attempts to lease an IP address
from a DHCP server on the network, and the IP address appears in this field (read-only) after it is
acquired. If this field is blank, the IP Address Configuration Method might be None, or the method might
be DHCP and the interface is unable to lease an address.
The IP subnet mask for the interface (also known as the network mask or netmask). This field can be
configured only when the selected IP Address Configuration Method is Manual.
The burned-in physical address of the interface. The format is six two-digit hexadecimal numbers
separated by colons, for example 00:06:29:32:81:40.
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.
Click to reset this field.
The configured bandwidth on this interface. This setting communicates the speed of the interface to
higher-level protocols.
The link layer encapsulation type for packets transmitted from the interface: Ethernet or SNAP.
Determines how the interface handles network-directed broadcast packets. A network-directed
broadcast is a broadcast directed to a specific subnet. If this option is selected, network directed
broadcasts are forwarded. If this option is cleared, network directed broadcasts are dropped.
When this option is selected, proxy ARP is enabled, and 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.
When this option is selected, local proxy ARP is enabled, and 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.
When this option is selected, the interface is allowed to send ICMP Destination Unreachable message
to a host if the intended destination cannot be reached for some reason. If this option is clear, the
interface will not send ICMP Destination Unreachable messages to inform the host about the error in
reaching the intended destination.
When this option is selected, 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.
To add a secondary IP address on the interface, click
the appropriate field in the Secondary IP Address Configuration window. You can add one or more
secondary IP addresses to an interface only if the interface already has a primary IP address. To remove
a configured secondary IP address, click the entry's associated
secondary IP addresses, click
The subnet mask associated with the secondary IP address. You configure this field in the Secondary IP
Address Configuration window.
