file transfer. The maximum file transfer speed supported is 57600 baud. This functionality primarily
serves as a disaster recovery technique in which you recover system images using Xmodem and
Ymodem commands on the ROM monitor from the console port on your Layer 3 switch router.
For more information on recovering a system image, see the “Recovering a System Image Using
Xmodem and Ymodem” section on page 3-10.
Passwords
There are two types of passwords that you can configure: an enable password and an enable secret
password. For maximum security, make the enable password 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 Layer 3 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 software, you enter the enable secret password before you can access global configuration
mode.You enter 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 Layer 3 switch router allows multiple simultaneous Telnet or SNMP
network management sessions. Since there is no separate management port on Layer 3 switch routers,
you can configure any Fast Ethernet or Gigabit Ethernet port as a management port.
You can remotely configure the Layer 3 switch router through the management port, but first you must
configure an IP address so that the Layer 3 switch router is reachable. You can manually configure the
management port interface from the CLI.
Note Before you begin configuring the management port interface manually, get the Layer 3 switch router
IP address and IP subnet mask. Also make sure the console cable is connected to the console port.
You can configure the management port from an IP-connected network.
