■
Serial Port—Allows or prevents access to the
management facilities via the serial port. You can
enable or disable access for each of the security
levels, including, Monitor, Secure Monitor, Man-
ager, Specialist.
For security reasons, the serial port access for security
level is enabled by default and cannot be changed.
■ Remote Telnet—Allows or prevents access to the
management facilities via the TCP/IP Telnet proto-
col. Because Telnet has no provision for security
and provides access to everyone, you can disable it
if your network has important or sensitive data.
■ Community-SNMP—Allows or prevents access to
the management facilities via SNMP using a
remote network management application.
Although SNMP has limited security features, it is
an unsecured protocol. You can disable SNMP
access if your network has important or sensitive
data.
