LOGGING IN THROUGH TELNET
Introduction You can telnet to a remote switch to manage and maintain the switch. To achieve
this, you need to configure both the switch and the Telnet terminal properly.

■ After you log in to the switch through Telnet, you can issue commands to the
switch by way of pasting session text, which cannot exceed 2000 bytes, and
the pasted commands must be in the same view; otherwise, the switch may
not execute the commands correctly.
■ If the session text exceeds 2000 bytes, you can save it in a configuration file,
upload the configuration file to the switch and reboot the switch with this
configuration file. For details, refer to “Configuration File Management” on
page 985.
■ The way to log in to a switch using Telnet based on IPv6 is the same as that
based on IPv4.
Common Configuration Table 11 lists the common Telnet configuration.
