Management Accounts
ExtremeWare XOS supports two levels of management accounts (local database of accounts and
passwords): User and Administrator. A user level account can view but not change all manageable
parameters, with the exception of the user account database and SNMP community strings. An
administrator level account can view and change all manageable parameters. For detailed information
about the configuring management accounts, see
Chapter 2 , “ Accessing the Switch .”
Using Telnet
ExtremeWare XOS supports the Telnet Protocol based on RFC 854. Telnet allows interactive remote
access to a device and is based on a client/server model. ExtremeWare XOS uses Telnet to connect to
other devices from the switch (client) and to allow incoming connections for switch management using
the CLI (server).
About the Telnet Client
Before you can start an outgoing Telnet session on the switch, you must set up the IP parameters
described in
“Configuring Switch IP Parameters” on page 47 . Telnet is enabled and uses VR-Mgmt by
default.
NOTE
Maximize the Telnet screen so that automatically updating screens display correctly.
If you use Telnet to establish a connection to the switch, you must specify the IP address or host name
of the device that you want to connect to. Check the user manual supplied with the Telnet facility if you
are unsure of how to do this.
After the connection is established, you see the switch prompt and you can log in.
The same is true if you use the switch to connect to another host. From the CLI, you must specify the IP
address or host name of the device that you want to connect to. If the host is accessible and you are
allowed access, you may log in.
For more information about using the Telnet client on the switch, see “Connecting to Another Host
Using Telnet” on page 47 .
About the Telnet Server
Any workstation with a Telnet facility should be able to communicate with the switch over a TCP/IP
network using VT100 terminal emulation.
Up to eight active Telnet sessions can access the switch concurrently. If you enable the
idletimeouts
parameter, the Telnet connection times out after 20 minutes of inactivity. If a connection to a Telnet
session is lost inadvertently, the switch terminates the session within two hours.
