Managing the Switch
ExtremeWare XOS 11.1 Concepts Guide

Disconnecting a Telnet Session
A person with an administrator level account can disconnect a Telnet management session. If this
happens, the user logged in by way of the Telnet connection is notified that the session has been
terminated.
To terminate a Telnet session:
1 Log in to the switch with administrator privileges.
2 Determine the session number of the session you want to terminate by using the following
command:
show session {{detail} {<sessID>}} {history}
3 Terminate the session by using the following command:
clear session [<sessId> | all]
Using Secure Shell 2
Secure Shell 2 (SSH2) is a feature of ExtremeWare XOS that allows you to encrypt session data between
a network administrator using SSH2 client software and the switch. Configuration and policy files may
also be transferred to the switch using the Secure Copy Program 2 (SCP2).
Up to eight active SSH2 sessions can run on the switch concurrently.
For detailed information about SSH2, see Chapter 13 , “ Security .”
Using the Trivial File Transfer Protocol
ExtremeWare XOS supports the Trivial File Transfer Protocol (TFTP) based on RFC 1350. TFTP is a
method used to transfer files from one network device to another. The ExtremeWare XOS TFTP client is
a command line application used to contact an external TFTP server on the network. For example,
ExtremeWare XOS uses TFTP to download software image files, switch configuration files, and ACLs
from a server on the network to the switch.
Up to eight active TFTP sessions can run on the switch concurrently.
For detailed information about downloading software image files, BootROM files, and switch
configurations, see
Chapter A , “ Software Upgrade and Boot Options .” Extreme Networks recommends
using a TFTP server that supports blocksize negotiation (as described in RFC 2348, TFTP Blocksize
Option ), to enable faster file downloads and larger file downloads.
For detailed information about downloading ACLs, see Chapter 13 , “ Security .”
Connecting to Another Host Using TFTP
You can TFTP from the current CLI session to another host using the following command:
tftp [<host_name> | <ip_address>] {-v <vr_name>} [-g | -p] [{-l [<local_file> |
memorycard <local-file-memcard>]} {-r <remote_file>} | {-r <remote_file>} {-l
[<local_file> | memorycard <local-file-memcard]}]
