8-Port Fast Ethernet Half-Height Line Card Configuration

This chapter describes procedures for configuring the Cisco 10000 series 8-Port Fast Ethernet Half-Height line card, hereafter known as the 8-Port Fast Ethernet Half-Height line card.

The 8-Port Fast Ethernet Half-Height line card contains eight 100BASE-TX ports. Each port autonegotiates between half and full duplex mode. Each port supports 100BASE-T, but does not support 10BASE-T.

This chapter contains the following sections:

•Software Support

•Default Values

•Management Port

•Configuring the Interface

Note For information about installing half-height line cards in subslot locations, see the Cisco 10000 Series Router Line Card Hardware Installation Guide.

Software Support

Table 9-1 shows the minimum Cisco IOS release on each release train that supports the 8-Port Fast Ethernet Half-Height line card.

Table 9-1 8-Port Fast Ethernet Half-Height Line Card Software Support

Required PRE

Minimum Cisco IOS Releases

PRE1

Cisco IOS Release 12.0(23)S and later releases of Cisco IOS 12.0S

PRE2

Cisco IOS Release 12.2(15)BX and later releases of Cisco IOS 12.2BX
Cisco IOS Release 12.3(7)XI and later releases of Cisco IOS 12.3 XI
Cisco IOS Release 12.2(28)SB and later releases of Cisco IOS 12.2SB

Checking Hardware and Software Compatibility

The PRE installed in the Cisco 10000 series router chassis must support the Cisco IOS software running on the router. Use the show version command to check the PRE version installed.

To see if a feature is supported by a Cisco IOS release, to locate the software document for that feature, or to check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl

This tool does not verify whether line cards within a system are compatible, but does provide the minimum Cisco IOS requirements for individual hardware line cards, modules, or options.

You must be a registered user on Cisco.com to access this tool.

Default Values

Table 9-2 lists default values for the 8-Port Fast Ethernet Half-Height line card.

Table 9-2 8-Port Fast Ethernet Half-Height Line Card Defaults

Parameter

Default Setting

Description

Speed

100 Mbps

You cannot use the speed command. The speed is advertised as 100 Mbps to the remote device.

Duplex

Autonegotiated

See the "Specifying Full or Half Duplex Mode" section to manually set the duplex value.

Note The Fast Ethernet line card only responds to 802.3x pause frames from another device when it autonegatiates the duplex mode (the default). The line card does not support 802.3x flow control when you manually set half-duplex or full-duplex mode.

Management Port

The Fast Ethernet interface 0/0/0 is reserved for management purposes only and cannot be used for such things as customer traffic or L2TP establishment. This interface also does not allow you to configure subinterfaces. However, the interface does allow radius, snmp, or telnet commands.

Configuring the Interface

To configure the 8-Port Fast Ethernet Half-Height line card interface, perform the following tasks:

•Specifying the Interface for Configuration

•Configuring the IP Address

•Specifying Full or Half Duplex Mode (optional)

•Configuring 802.1Q VLAN Encapsulation (optional)

•Configuring Routing

•Saving the Configuration

•Viewing the Configuration (optional)

•Disabling the Interface (optional)

For quick reference, refer to the configuration task commands below:
Router# configure terminal
Router(config)# interface FastEthernet slot/subslot/port
Router(config-if)# ip address ip-address mask
Router(config-if)# [no] {full-duplex | half-duplex} (optional)
Router(config-if)# [no] encapsulation dot1q vlan-id [native] (optional)
Router(config-if)# exit
Router(config)# router rip (For instance, use to configure RIP)
Router(config-router)# network ip-address
Router(config-router)# end
Router# copy running-config startup-config
Specifying the Interface for Configuration

Follow these steps to specify the interface that you want to configure:

Step 1 Enter global configuration mode by entering:
Router# configure terminal
Step 2 Specify the interface you want to configure by entering:
Router(config)# interface FastEthernet slot/subslot/port
•slot—1 to 8 on the Cisco 10008 series router; 1 to 5 on the Cisco 10005 series router (slots 0A and 0B are used for the PREs).

•subslot—0 or 1. 0 is the top subslot.

•port—0 to 7.

Note Fast Ethernet 0/0/0 is reserved for management purposes only. Do not use this interface for such things as customer traffic or L2TP establishment. This interface does not allow you to configure subinterfaces.

Configuring the IP Address

To set the IP address of the interface, enter the following command:
Router(config-if)# ip address ip-address mask
Specifying Full or Half Duplex Mode

If the negotiation of the duplex mode fails, and a duplex mode mismatch occurs, manually set the duplex mode.

Note The 8-Port Fast Ethernet Half-Height line card only responds to 802.3x pause frames from another device when it autonegotiates the duplex mode (the default). The line card does not support 802.3x flow control when you manually set half-duplex or full-duplex mode.

Set the duplex mode using the following command:
Router(config-if)# [no] {half-duplex | full-duplex}
The no option disables the duplex setting. If no duplex mode is set, the mode reverts to autonegotiation.

Configuring 802.1Q VLAN Encapsulation

The 8-Port Fast Ethernet Half-Height line card supports 802.1Q VLAN encapsulation. The card does not support Inter-Switch Link (ISL) encapsulation. To set 802.1Q encapsulation, enter:
Router(config-if)# [no] encapsulation dot1q vlan-id [native]
•vlan-id—The VLAN identifier, between 1 and 1000.

•native—Sets the Port VLAN ID (PVID) value of the port to the vlan-id value.

•no—Disables encapsulation.

Configuring Routing

See the Cisco IOS Command References for information about configuring routing protocols, such as RIP or OSPF.

Saving the Configuration

After completing your configuration changes, save the configuration by following these steps:

Step 1 To exit configuration mode, either enter Ctrl-Z or enter the following command:
Router(config-if)# end
Step 2 Write the new configuration to memory by entering:
Router# copy running-config startup-config
When the configuration is stored, an OK message appears.

Viewing the Configuration

You can check the configuration using the following command:
Router# show interface FastEthernet slot/subslot/port
Disabling the Interface

The interface is enabled by default. To disable it, enter:
Router(config-if)# shutdown
To enable the interface, enter:
Router(config-if)# no shutdown
