Managing the Router Using the Network Management Ethernet
Port
The network management Ethernet (NME) port on the PRE3 is used to manage the Cisco 10008 router.
The duplex mode and speed of the NME port are configurable.
The following sections describe how to configure the duplex mode and speed of the NME port for the
PRE3.
Configuring the NME Port on the PRE3
The NME port for PRE3 supports the following operational modes:
• Autonegotiation (the default)
• Full-duplex
• Half-duplex
Default configurations do not appear in the router’s configuration file.
We recommend that you allow the NME port to autonegotiate the duplex mode. When autonegotiation
mode is enabled, the NME port responds only to IEEE 802.3x pause frames from another device.
If the negotiation of duplex mode fails and a duplex mode mismatch occurs, manually set the duplex
mode for full-duplex or half-duplex operation. Setting duplex mode disables autonegotiation mode.
When you manually set duplex mode, the NME port does not support IEEE 802.3x flow control.
When you manually configure duplex mode, the NME port can experience problems. 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 for the PRE3, page 24
• Manually Setting the Speed for the NME Port for the PRE3, page 25
Manually Setting the Duplex Mode for the NME Port for the PRE3
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 the PRE3, enter either of the following
commands in interface configuration mode:
