Dowslake Network Management
A network management system shall provide Fault, Configuration, Administration, Performance and Security Management. Based on such requirement, Dowslake provides several options depending on customer need and the
sophistication of the network.
Command Line Interface (CLI)
All Dowslake equipment comes with CLI without exception. CLI can
The general syntax for a CLI command is as below:

SNMP
All Dowslake equipment comes with SNMP without exception.
Simple Network Management Protocol (SNMP) is a protocol defined
by the Internet Engineering Task Force (IETF). Network devices supporting this protocol, such as Dowslake equipment, allow a management station to monitor network status, modify network settings, and
receive network events.
A SNMP network management system consists of:
- one or more managed nodes, such as a Dowslake MTS carrier
switch, each of which runs one or more SNMP agents. An agent
keeps information about its managed node in a database called a
Management Information Base (MIB).
b. CLI Commands
- one or more network management stations, which runs network
