Chapter 3 Initial Configuration

Configuring Loopback Interfaces

All CLI commands mentioned in this section are described in Chapter 6: X330WAN CLI Commands.

To configure Loopback interfaces:

1Enter the Interface Loopback mode using the

interface Loopback [<interface number>[.ip-interface]] command.

For example: typing interface loopback 1 enters a context for configuring the Loopback1 interface parameters.

The prompt changes to X330WAN-2DS1-N(super-if:Loopbackn)# where N is the switch number and n is the Loopback interface number.

2Use the ip address <ip address> <mask> command to assign an IP address and subnet mask to the interface.

3Type exit to return to Supervisor mode.

The prompt returns to X330WAN-2DS1-N(super)#

Note: The first IP interface created in the X330WAN automatically becomes the PMI (Primary Management Interface), described in detail on page 34. It is recommended to configure the Loopback interface as the first Layer 2 interface and to configure an IP interface on it. After the PMI is configured, the following message appears:

The primary management interface has changed.

For this change to take effect, you need to copy running-config startup-config and then reset the device.

Enter the copy running-configstartup-configand reset commands at this stage.

Configuring Fast Ethernet Interfaces

All CLI commands mentioned in this section are described in Chapter 6: X330WAN CLI Commands.

To configure Fast Ethernet interfaces:

1Type interface FastEthernet 1 to enter the Interface Configuration mode. The prompt changes to X330WAN-2DS1-N(super-if:FastEthernet1)#

2Use the ip address <ip address> <mask> command to assign an IP address and subnet mask to the interface.

3Type exit to return to Supervisor mode.

The prompt returns to X330WAN-2DS1-N(super)#

Note: The first IP interface created in the X330WAN automatically becomes the PMI, described in detail on page 34. It is recommended to configure the Loopback interface as the first Layer 2 interface and to configure an IP interface on it. After the
