Chapter 3 Initial Switch Router Configurations

Configuring the Management Port

Xmodem or Ymodem protocols. The Xmodem and Ymodem protocols support different speeds of file transfers. The maximum file transfer speed supported is 57600 baud. This functionality primarily serves as a disaster recovery technique where system images are recovered using Xmodem and Ymodem commands on the ROM monitor from the console port on your switch router.

See the “Recovering a System Image Using Xmodem and Ymodem” section on page 3-11.

About Passwords

There are two types of passwords.You can configure both an enable password and an enable secret password. For maximum security, the enable password should be different from the enable secret password.

•Enable password—The enable password is a nonencrypted password. It can contain any number of uppercase and lowercase alphanumeric characters. Give the enable password only to users permitted to make configuration changes to the switch router.

•Enable secret password—The enable secret password is a secure, encrypted password. By setting an encrypted password, you can prevent unauthorized configuration changes. On systems running Cisco IOS, you must type in the enable secret password before you can access global configuration mode.You must type in the enable secret password to access boot ROM software.

An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters. The first character cannot be a number. Spaces are valid password characters. Leading spaces are ignored; trailing spaces are recognized.

You will configure passwords in the next section, “Configuring the Management Port.”

Configuring the Management Port

The management port on the switch router allows multiple simultaneous Telnet or SNMP network management sessions. Since there is no separate management port on the Layer 3 switch routers, you can configure any Fast Ethernet or Gigabit Ethernet port as a management port.

You can remotely configure the switch router through the management port, but first you must configure an IP address so that the switch router is reachable. You can manually configure the management port interface from the command-line interface (CLI).

Note Before you begin to configure the management port interface manually, obtain the switch router’s IP address and IP subnet mask. Also make sure the console cable is connected to the console port.
