Cisco 10000 Series Router Performance Routing Engine Installation

OL-3971-03

Managing the Router Using the Network Management Ethernet Port

When you manually configure duplex mode, the NME port can experience problems such as flapping. If

this occurs, disable duplex mode by entering the no full-duplex or no half-duplex command. When you

enter the no duplex command, the operational mode reverts to autonegotiation mode.

To configure the NME port, perform the following optional configuration tasks:

• Manually Setting the Duplex Mode for the NME Port—ESR-PRE or ESR-PRE1, page 32

• Manually Setting the Speed for the NME Port—ESR-PRE or ESR-PRE1, page 32

Manually Setting the Duplex Mode for the NME Port—ESR-PRE or ESR-PRE1

Note We recommend that you allow the NME port to autonegotiate (default setting) duplex mode.

To manually set the duplex operational mode of the NME port for ESR-PRE or ESR-PRE1, enter either

of the following commands in interface configuration mode:

Manually Setting the Speed for the NME Port—ESR-PRE or ESR-PRE1

The Cisco IOS software automatically negotiates the speed of the NME port for ESR-PRE or ESR-PRE1.

You cannot manually set the speed of the NME port.

Configuring the NME Port—ESR-PRE2

The NME port for ESR-PRE2 supports the following operational modes:

• Autonegotiation

• Full-duplex (the default)

• Half-duplex

The NME port defaults to 100 Mbps full-duplex mode. Default configurations do not appear in the

configuration file.

Command Purpose

Router(config-if)# full-duplex

Configures the NME port for full-duplex operational mode.

For ESR-PRE1, the full-duplex command appears in the router’s

configuration file. If the configuration file does not specify a

duplex mode, half-duplex mode is implied.

Note To return the system to its default duplex mode

(autonegotiation), enter the no duplex command.

Router(config-if)# half-duplex

Configures the NME port for half-duplex operational mode.

For ESR-PRE1, the half-duplex command does not appear in the

router’s configuration file, but it is implied.

Note To return the system to its default duplex mode

(autonegotiation), enter the no duplex command.
