Chapter 4 Command-Line Reference 4-3
4.1.1.2 Telnet Connection
Telnet operates over the IP transport protocol. In this environment, your
management station and any network device you want to manage over the network
must have a valid IP address. Valid IP addresses consist of four numbers, 0 to 255,
separated by periods. Each address consists of a network portion and host portion.
For example, the IP address, 10.1.0.1, consists of a network portion (10.1.0) and a
host portion (1).
Note – The IP address for the switch is unassigned by default. The management
port (NETMGT) is assigned to VLAN 2. This port cannot be assigned to a VLAN that
contains up-link or down-link ports.
To access the switch through a Telnet session, you must first set the IP address for
the switch, and set the default gateway if you are managing the switch from a
different IP subnet. For example:
If your corporate network is connected to another network outside your office or to
the Internet, you need to apply for a registered IP address. However, if you are
attached to an isolated network, then you can use any IP address that comforms
with your site’s network policy.
After you configure the switch with an IP address, you can open a Telnet session by
performing these steps:
1. From the remote host, enter the Telnet command and the IP address of the device
you want to access.
2. At the prompt, type the user name and system password.
The CLI displays the Vty-0# prompt for the administrator to show that you are
using privileged access mode (Privileged Exec), or Vty-0> for the guest to show
that you are using normal access mode (Normal Exec).
3. Type the necessary commands to complete your desired tasks.
4. When finished, exit the session with the quit or exit command.
