2Fill in the fields according to these descriptions:

■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.
