| Logical
Interfaces |
|
Add logical interfaces
|
Defines one or more logical units that you connect to this physical
Fast Ethernet interface. You must define at least one logical unit
for a Fast Ethernet interface. You can define multiple units if the
encapsulation type is Frame Relay.
|
Click Add.

|
Logical Interface Description
|
(Optional) Describes the logical interface.
|
Type a text description of the logical interface to more clearly
identify it in monitoring displays.
|
|
IPv4 Addresses and Prefixes
|
Specifies one or more IPv4 addresses for the interface.
|
- Type one or more IPv4 addresses and prefixes.
For example:
10.10.10.10/24
- Click Add.
- Click OK.
|
|
ARP Address
|
Enables the device to create a static Address Resolution Protocol
(ARP) entry for this interface by specifying the IP address of a node
to associate with its media access control (MAC) address. The IP address
must be in the same subnet as the IPv4 address or prefix of the interface
you are configuring.
Static ARP entries associate the IP addresses and MAC addresses
of nodes on the same subnet, enabling a device to respond to ARP requests
having destination addresses that are not local to the incoming interface.
|
Type an IPv4 address that you want to associate with the MAC
address—for example, 10.10.10.1.
|
|
MAC Address
|
Specifies the hardware media access control (MAC) address associated
with the ARP address.
The MAC address uniquely identifies the system and is expressed
in the following format: mm:mm:mm:ss:ss:ss. The first three
octets denote the hardware manufacturer ID, and the last three are
serial numbers identifying the device.
|
Type the MAC address to be mapped to the ARP entry—for
example, 00:12:1E:A9:8A:80.
|
|
Publish
|
Enables the device to reply to ARP requests for the specified
address.
|
- To enable publishing, select the check box.
- To disable publishing, clear the check box.
|
|
Physical Interface Description
|
(Optional) Adds supplementary information about the physical
Fast Ethernet interface.
|
Type a text description of the Fast Ethernet interface to more
clearly identify it in monitoring displays.
|
|
MTU (bytes)
|
Specifies the maximum transmission unit size for the Fast Ethernet
interface.
|
Type a value between 256 bytes and one of the
following values:
- For built-in Fast Ethernet interfaces and Dual-Port Fast
Ethernet PIM interfaces, 9192 bytes
- For 4-Port Fast Ethernet ePIM interfaces, 1514 bytes
The default MTU for Fast Ethernet interfaces is 1514.
|
|
Per unit scheduler
|
Enables scheduling on logical interfaces.
Allows you to configure multiple output queues on a logical
interface and associate an output scheduler and shaping rate with
the queues.
|
- To enable scheduling, select the check box.
- To disable scheduling, clear the check box.
