Commands for Managing the Switch
Telnet
Telnet allows you to access the switch remotely using TCP/IP through one of the switch ports or a
workstation with a Telnet facility. If you access the switch via Telnet, you will use the command line
interface (CLI) to manage the switch and modify switch configurations.
TFTP
ExtremeWare XOS supports the client portion of Trivial File Transfer Protocol (TFTP) based on RFC
1350. The TFTP client is a command line application used to contact an external TFTP server on the
network. For example, XOS uses TFTP to download software image files, switch configuration files, and
access control lists (ACLs) from a server on the network to the switch.
Simple Network Time Protocol
ExtremeWare XOS supports the client portion of the Simple Network Time Protocol (SNTP) Version 3
based on RFC1769. SNTP can be used by the switch to update and synchronize its internal clock from a
Network Time Protocol (NTP) server. When enabled, the switch sends out a periodic query to the
indicated NTP server, or the switch listens to broadcast NTP updates. In addition, the switch supports
the configured setting for Greenwich Mean time (GMT) offset and the use of Daylight Saving Time.
These features have been tested for year 2000 compliance.
