To establish a console connection with the switch:
1. Connect the terminal to the console port using the null modem cable.
2. Power on the terminal.
3. Press the Enter key a few times on the terminal to establish the connection.
4. You will be required to enter a password for access to the switch.
Setting an IP address
To access the switch via a Telnet or an SSH connection, you need to have an Internet Protocol (IP)
address set for the switch. The switch can get its IP address in one of the following ways:
Management port access:
Using a Dynamic Host Control Protocol (DHCP) server—When the dhcp client is enabled, the
management interface (interface 250) requests its IP address from a DHCP server. The default
value for the dhcp client is enabled.
Configuring manually—If the network does not support DHCP, you must configure the
management interface (interface 250) with an IP address. If you want to access the switch from
a remote network, you also must configure the management gateway (gateway 254).
Uplink port access:
Using a Bootstrap Protocol (BOOTP) server—By default, the management interface is set up to
request its IP address from a BOOTP server. If you have a BOOTP server on the network, add the
Media Access Control (MAC) address of the switch to the BOOTP configuration file located on
the BOOTP server. The MAC address can be found in the System Information menu (See the
―System Information commands‖ section in the ―Information Commands‖ chapter.) If you are
using a DHCP server that also does BOOTP, you do not have to configure the MAC address.
Configuring manually—If the network does not support BOOTP, you must configure the
management port with an IP address.
Establishing a Telnet connection
A Telnet connection offers the convenience of accessing the switch from any workstation connected to
the network. Telnet provides the same options for user, operator, and administrator access as those
available through the console port. By default, Telnet is enabled on the switch. The switch supports 4
concurrent Telnet connections.
Once the IP parameters are configured, you can access the ISCLI using a Telnet connection. To establish
a Telnet connection with the switch, run the Telnet program on the workstation and enter the telnet
command, followed by the switch IP address:
telnet <10Gb Intelligent L3 Switch IP address>
You will then be prompted to enter a password. The password determines the access level: administrator,
operator, or user. See the ―Accessing the switch‖ section later in this chapter for description of default
passwords.
Establishing an SSH connection
Although a remote network administrator can manage the configuration of a switch via Telnet, this
method does not provide a secure connection. The Secure Shell (SSH) protocol enables you to securely
log into this switch over the network.
As a secure alternative to using Telnet to manage switch configuration, SSH ensures that all data sent
over the network is encrypted and secure. In order to use SSH, you must first configure it on the switch.
See the ―Secure Shell Server configuration‖ section in the ―Configuration Commands‖ chapter for
information on how to configure SSH.
The switch can perform only one session of key/cipher generation at a time. Therefore, an SSH/Secure
Copy (SCP) client will not be able to log in if the switch is performing key generation at that time or if
another client has just logged in before this client. Similarly, the system will fail to perform the key
generation if an SSH/SCP client is logging in at that time.
