Configuring Interfaces on the ML-Series Card

This chapter describes basic interface configuration for the ML-Series card to help you get your ML-Series card up and running. Advanced packet-over-SONET (POS) interface configuration is covered in Chapter 6, "Configuring POS on the ML-Series Card." For more information about the Cisco IOS commands used in this chapter, refer to the Cisco IOS Command Reference publication.

This chapter contains the following major sections:

•General Interface Guidelines

•Basic Interface Configuration

•Basic Fast Ethernet and POS Interface Configuration

•Monitoring Operations on the Fast Ethernet Interfaces

General Interface Guidelines

The main function of the ML-Series card is to relay packets from one data link to another. Consequently, you must configure the characteristics of the interfaces, which receive and send packets. Interface characteristics include, but are not limited to, IP address, address of the port, data encapsulation method, and media type.

Many features are enabled on a per-interface basis. Interface configuration mode contains commands that modify the interface operation (for example, of an Ethernet port). When you enter the interface command, you must specify the interface type and number.

The following general guidelines apply to all physical and virtual interface configuration processes:

•All interfaces have a name that is composed of an interface type (word) and a Port ID (number). For example, Fast Ethernet 2.

•Configure each interface with a bridge-group or IP address and IP subnet mask.

•VLANs are supported through the use of subinterfaces. The subinterface is a logical interface configured separately from the associated physical interface.

•Each physical interface, including the internal POS interfaces, has an assigned MAC address.

MAC Addresses

Every port or device that connects to an Ethernet network needs a MAC address. Other devices in the network use MAC addresses to locate specific ports in the network and to create and update routing tables and data structures.

To find MAC addresses for a device, use the show interfaces command, as follows: 

ML_Series# show interfaces fastethernet 0

FastEthernet0 is up, line protocol is up

  Hardware is epif_port, address is 000b.fcfa.339e (bia 000b.fcfa.339e)

Interface Port ID

The interface port ID designates the physical location of the interface within the ML-Series card. It is the name that you use to identify the interface you are configuring. The system software uses interface port IDs to control activity within the ML-Series card and to display status information. Interface port IDs are not used by other devices in the network; they are specific to the individual ML-Series card and its internal components and software.

The ML-100T-8 port IDs for the eight Fast Ethernet interfaces are Fast Ethernet 0 through 7. The ML-Series card features two POS ports. The ML-Series port IDs for the two POS interfaces are POS 0 and 1. You can use user-defined abbreviations such as f0 through f7 to configure the eight Fast Ethernet interfaces, and POS0 and POS1 to configure the two POS ports.

You can use Cisco IOS show commands to display information about any or all the interfaces of the ML-Series card.

Basic Interface Configuration

The following general configuration instructions apply to all interfaces. Before you configure interfaces, develop a plan for a bridge or routed network.

To configure an interface, do the following:

Step 1 Enter the configure EXEC command at the privileged EXEC prompt to enter global configuration mode. The key word your-password is the password set up by the user in the initial configuration of the ML-Series card. 

ML_Series> enable

Password:<your-password>

ML_Series# configure terminal

ML_Series(config)#

Step 2 Enter the interface command, followed by the interface type (for example, fastethernet or pos) and its interface port ID (see the "Interface Port ID" section).

For example, to configure a Fast Ethernet port, enter this command: 

ML_Series(config)# interface fastethernet number

Step 3 Follow each interface command with the interface configuration commands required for your particular interface.

The commands you enter define the protocols and applications that will run on the interface. The
ML-Series card collects and applies commands to the interface command until you enter another interface command or a command that is not an interface configuration command. You can also enter end to return to privileged EXEC mode.

Step 4 Check the status of the configured interface by entering the EXEC show interface command. 

ML_Series# show interfaces fastethernet 0

FastEthernet0 is up, line protocol is up

  Hardware is epif_port, address is 000b.fcfa.339e (bia 000b.fcfa.339e)

Basic Fast Ethernet and POS Interface Configuration

ML-Series cards support Fast Ethernet and POS interfaces. This section provides some examples of configurations for all interface types.

To configure an IP address or bridge-group number on a Fast Ethernet or POS interface, perform the following procedure, beginning in global configuration mode:

 
Command
Purpose

Step 1  

ML_Series(config)# interface type number

Activates interface configuration mode to configure either the Fast Ethernet interface or the POS interface.

Step 2  

ML_Series(config-if)# {ip address 
ip-address subnet-mask | bridge-group 
bridge-group-number}

Sets the IP address and IP subnet mask to be assigned to the interface.

or

Assigns a network interface to a bridge group.

Step 3  

ML_Series(config-if)# no shutdown

Enables the interface by preventing it from shutting down.

Step 4  

ML_Series(config)# end

Returns to privileged EXEC mode.

Step 5  

ML_Series# copy running-config 
startup-config

(Optional) Saves configuration changes to flash database.

Configuring the Fast Ethernet Interfaces

To configure the IP address or bridge-group number, autonegotiation, and flow control on a Fast Ethernet interface, perform the following procedure, beginning in global configuration mode:

 
Command
Purpose

Step 1  

ML_Series(config)# interface fastethernet 
number

Activates interface configuration mode to configure the Fast Ethernet interface.

Step 2  

ML_Series(config-if)# {ip address 
ip-address subnet-mask | bridge-group 
bridge-group-number}

Sets the IP address and IP subnet mask to be assigned to the interface.

or

Assigns a network interface to a bridge group.

Step 3  

ML_Series(config-if)# [no] speed {10 | 100 
| auto}

Configures the transmission speed for 10 or 100 Mbps. If you set the speed or duplex for auto, you enable autonegotiation on the system—the ML-Series card matches the speed and duplex mode of the partner node.

Step 4  

ML_Series(config-if)# [no] duplex {full | 
half | auto}

Sets full duplex, half duplex, or autonegotiate mode.

Step 5  

ML_Series(config-if)# flowcontrol send {on 
| off | desired}

(Optional) Sets the send flow control value for an interface. Flow control works only with port-level policing. ML-Series card Fast Ethernet port flow control is IEEE 802.3x compliant.

Step 6  

ML_Series(config-if)# no shutdown

Enables the interface by preventing it from shutting down.

Step 7  

ML_Series(config)# end

Returns to privileged EXEC mode.

Step 8  

ML_Series# copy running-config 
startup-config

(Optional) Saves your configuration changes to the flash database.

Example 5-1 shows how to do the initial configuration of a Fast Ethernet interface with an IP address, autonegotiated speed, and autonegotiated duplex.

Example 5-1 Initial Configuration of a Fast Ethernet Interface 

ML_Series(config)# interface fastethernet 1

ML_Series(config-if)# ip address 10.1.2.4 255.0.0.0

ML_Series(config-if)# speed auto

ML_Series(config-if)# duplex auto

ML_Series(config-if)# no shutdown

ML_Series(config-if)# end

ML_Series# copy running-config startup-config

Configuring the POS Interfaces

Encapsulation changes on POS ports are allowed only when the interface is in a manual shutdown (ADMIN_DOWN). For advanced POS interface configuration, see Chapter 6, "Configuring POS on the ML-Series Card."

Note The initial state of the ONS 15310-CL ML-Series card POS port is inactive. A POS interface command of no shutdown is required to carry traffic on the SONET circuit.

To configure the IP address, bridge group, or encapsulation for the POS interface, perform the following procedure, beginning in global configuration mode:

 
Command
Purpose

Step 1  

ML_Series(config)# interface pos number

Activates interface configuration mode to configure the POS interface.

Step 2  

ML_Series(config-if)# {ip address 
ip-address subnet-mask | bridge-group 
bridge-group-number}

Sets the IP address and subnet mask.

or

Assigns a network interface to a bridge group.

Step 3  

ML_Series(config-if)# shutdown

Manually shuts down the interface. Encapsulation changes on POS ports are allowed only when the interface is shut down (ADMIN_DOWN).

Step 4  

ML_Series(config-if)# encapsulation type

Sets the encapsulation type. Valid values are:

•hdlc—Cisco high-level data link control (HDLC)

•lex—(Default) LAN extension, special encapsulation for use with Cisco ONS Ethernet line cards

•ppp—Point-to-Point Protocol

Note Under GFP-F framing, the ONS 15310-CL ML-Series card is restricted to LEX encapsulation.

Step 5  

ML_Series(config-if)# no shutdown

Restarts the shutdown interface.

Step 6  

ML_Series(config)# end

Returns to privileged EXEC mode.

Step 7  

ML_Series# copy running-config 
startup-config

(Optional) Saves configuration changes to NVRAM.

Monitoring Operations on the Fast Ethernet Interfaces

To verify the settings after you have configured the interfaces, enter the show interface command. For additional information on monitoring the operations on POS interfaces, see the "Configuring POS on the ML-Series Card" chapter.

Example 5-2 shows the output from the show interface command, which displays the status of the interface including port speed and duplex operation.

Example 5-2 show interface Command Output
