Configuring Ethernet Management Port

Prerequisites for Ethernet Management Ports

When connecting a PC to the Ethernet management port, you must first assign an IP address.

Information About the Ethernet Management Port

The Ethernet management port, also referred to as the Fa0 or fastethernet0 port, is a Layer 3 host port to which you can connect a PC. You can use the Ethernet management port instead of the device console port for network management. When managing a device stack, connect the PC to the Ethernet management port on a stack member.

Ethernet Management Port Direct Connection to a Device

Figure 1. Connecting a Switch to a PC. This figure displays how to connect the Ethernet management port to the PC for a device or a standalone device.

Ethernet Management Port Connection to Stack Devices using a Hub

In a stack with only stack devices, all the Ethernet management ports on the stack members are connected to a hub to which the PC is connected. The active link is from the Ethernet management port on the stack's active switchthrough the hub, to the PC. If the activedevice fails and a new active device is elected, the active link is now from the Ethernet management port on the new active device to the PC.

Figure 2. Connecting a Device Stack to a PC. This figure displays how a PC uses a hub to connect to a device stack.

The Ethernet management port supports these features:

  • Express Setup (only in switch stacks)

  • Network Assistant

  • Telnet with passwords

  • TFTP

  • Secure Shell (SSH)

  • DHCP-based autoconfiguration

  • SMNP (only the ENTITY-MIB and the IF-MIB)

  • IP ping

    • Speed—10 Mb/s, 100 Mb/s, and autonegotiation

    • Duplex mode—Full, half, and autonegotiation

    • Loopback detection

  • Cisco Discovery Protocol (CDP)

  • DHCP relay agent

  • IPv4 and IPv6 access control lists (ACLs)


Caution

Before enabling a feature on the Ethernet management port, make sure that the feature is supported. If you try to configure an unsupported feature on the Ethernet Management port, the feature might not work properly, and the device might fail.

How to Configure the Ethernet Management Port

Disabling and Enabling the Ethernet Management Port

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

interface fastethernet0

Example:

Device(config)# interface fastethernet0

Specifies the Ethernet management port in the CLI.

Step 3

shutdown

Example:

Device(config-if)# shutdown

Disables the Ethernet management port.

Step 4

no shutdown

Example:

Device(config-if)# no shutdown

Enables the Ethernet management port.

Step 5

exit

Example:

Device(config-if)# exit

Exits interface configuration mode.

Step 6

show interfaces fastethernet0

Example:

Device# show interfaces fastethernet0

Displays the link status.

To find out the link status to the PC, you can monitor the LED for the Ethernet management port. The LED is green (on) when the link is active, and the LED is off when the link is down. The LED is amber when there is a POST failure.

What to do next

Proceed to manage or configure your switch using the Ethernet management port. Refer to the Catalyst 2960-X Switch Network Management Configuration Guide.
