4-14 Configuring IPmux-24 for Management IPmux-24 Ver. 1.5
Controlling Management Access
You can enable or disable access to the IPmux-24 management system via an
SNMP, Telnet or Web-based application. By disabling SNMP, Telnet or Web, you
prevent unauthorized access to the system when security of the IPmux-24 IP
address has been compromised. When SNMP, Telnet and Web access is disabled,
IPmux-24 can be managed via an ASCII terminal only. In addition, you can limit
access to the device to only the stations defined in the manager list.
