IPmux-8/16 Ver. 6.00 Configuring IPmux-8/16 for Management 4-7
Controlling Telnet Access
You can enable or disable access to the IPmux-8/16 management system via
Telnet. By disabling Telnet, you prevent unauthorized access to the system when
security of the IPmux-8/16 IP address has been compromised. When Telnet access
is disabled, IPmux-8/16 closes the TCP port, allowing management via an ASCII
terminal only. In addition, you can allow Telnet only for the network management
stations defined via the Managers List menu (
Figure 4-3).
If no network managers are defined, Telnet access is allowed for all users.

Controlling SNMP Access
You can enable or disable access to the IPmux-8/16 management system via
SNMP. When SNMP access is disabled, IPmux-8/16 closes the UDP port (161),
allowing management via an ASCII terminal or a Telnet host. In addition, you can
allow SNMP access only for the network management stations defined via the
Managers List menu (
Figure 4-3).
• If no network managers are defined, SNMP access is disabled for all users.
• SNMP access configuration is available only in terminal and Telnet management
sessions.
• No SNMP traps are sent, when the SNMP access is disabled.
