46 ExtremeWare XOS 11.0 Concepts Guide
Managing the Switch
To change the default TCP port number, use the following command:
configure telnet port [<portno> | default]
The range for the port number is 1 through 65535.
To display the status of Telnet, including the current TCP port, and the virtual router used to establish a
Telnet session, use the following command:
show management
You can choose to disable Telnet by using the following command:
disable telnet
To re-enable Telnet on the switch, use the following command:
enable telnet
You must be logged in as an administrator to configure the virtual router(s) used by Telnet and to
enable or disable Telnet.
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 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), to enable faster file
downloads and larger file downloads.
For detailed information about downloading ACLs, see Chapter 10, “Security.”
