System Management

• VCL-GigEoSDH supports management via CLI command based on serial RS232 port (CONSOLE) and telnet (EMU interface).
• VCL-GigEoSDH also supports network management platform based on SNMP (V1 and V2C) to complete configuration management and kinds of alarm monitoring.

Note：The IP address of PC and the equipment should be in the same IP network segment.
