The access levels are defined as:
Monitor — This allows the user to view the essential
operations of the hub and to establish whether or
not the hub is operating correctly. A user at this level
cannot change the operating parameters of the hub.
Secure Monitor — In this implementation, Secure
Monitor has the same rights as Monitor.
Manager — This allows the user to monitor and
change the operational parameters of the hub. The
user cannot create or delete other users, re-initialize
the hub or download a software image.
Specialist — In this implementation, Specialist has
the same rights as Manager.
Security — This allows the user to access all the
management operations. This level of security should
be assigned only to the system administrator or
somebody with the system administrator's
responsibilities.
To prevent you from locking yourself out from the
hub completely, console port access is always kept
enabled for the security access level.

Console Port Enabled / Disabled
To prevent access to the management facilities
through the console port, disable access to the
facility for each access level. To allow you to
configure the hub locally in the event of problems on
your network, we suggest that you change the
default password for the permanently-enabled
security access level, see "Editing Users" on
page 5-18 .
Remote Telnet Enabled / Disabled
Telnet is an insecure protocol. You may wish to
disable all access to the management facilities
through Telnet if there is important or secret data on
your network.
Community SNMP Enabled / Disabled
The hub can be managed through SNMP using a
remote network manager. 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 through Community
SNMP if there is important or secret data on your
network.
