User Access Level 3 - 19
DUA1663-0BAA0 3
■
Specialist - In this implementation, Specialist has the same rights as
Manager.
■
Security - This level of security allows a user access to all the
management operations. This level of security should be assigned only
to the system administrator or somebody with the system
administrator's responsibilities.
All the fields are choice fields. The options for each field are Enabled
(the default) or Disabled .
To prevent you from locking yourself out from the stack completely,
serial port access is always kept enabled for the security access level.
Make any changes you require, then move the cursor to the OK button
and press [Return]. Remember that you can use [Ctrl]+[B] to jump to
the OK button.
Serial Port (Choice Field) Enabled / Disabled
To prevent access to the management facilities via the serial port,
disable access to the facility for each access level. To allow you to
configure the stack locally in the event of problems on your network,
we suggest that you change the default password (see “Edit User” on
page 3-21 ) for the permanently-enabled security access level.
Remote Telnet (Choice Field) Enabled / Disabled
Telnet is an insecure protocol. You may wish to disable all access to the
management facilities via Telnet if there is important or secret data on
your network.
Community SNMP (Choice Field) Enabled / Disabled
The stack can be managed via SNMP using a remote network manager
such as Transcend WorkGroup Manager for Windows. Community
SNMP does have some simple security features but it is an insecure
protocol. You may wish to disable all access to the management
facilities via Community SNMP if there is important or secret data on
your network.
