Using Telnet
Using Secure Shell

The G8264CS supports an industry standard command‐line interface (ISCLI) that
you can use to configure and control the switch over the network using the Telnet
program. You can use the ISCLI to perform many basic network management
functions. In addition, you can configure the switch for management using an
SNMP‐based network management system or a Web browser.

A Telnet connection offers the convenience of accessing the switch from a
workstation connected to the network. Telnet access provides the same options for
user and administrator access as those available through the console port.
By default, Telnet access is enabled. Use the following commands to disable or
re‐enable Telnet access:
RS 8264CS(config)# [no] access telnet enable
Once the switch is configured with an IP address and gateway, you can use Telnet
to access switch administration from any workstation connected to the
management network.
To establish a Telnet connection with the switch, run the Telnet program on your
workstation and issue the following Telnet command:
telnet <switch IPv4 or IPv6 address>
You will then be prompted to enter a password as explained "Switch Login Levels"
on page
49.
Two attempts are allowed to log in to the switch. After the second unsuccessful
attempt, the Telnet client is disconnected via TCP session closure.
Although a remote network administrator can manage the configuration of a
G8264CS via Telnet, this method does not provide a secure connection. The Secure
Shell (SSH) protocol enables you to securely log into another device over a network
