SNMP Network Management IMACS-200 General Features

4.5SNMP Network Management

SNMP access allows users to remotely gather information, provision, test and monitor the IMACS 200. This section presents this type of Network Management System (NMS) for diagnosing and reporting trouble at unsupervised locations. The SNMP alarm traps and configuration can connect using this alternate method. Both formats can use either the SA4 on an E1 link, or a full DS0 on a T1 or E1 link.

If you do not understand the NMS concepts of IP addressing, SNMP, TELNET, and Ping, please consult with your network administrator before attempting to install or repair components presented in this section.

The first step in starting an operator session is to log into the system. You must enter a password that allows you to perform the required tasks on the system. The initial (default) SNMP Default Passwords / Community Names correspond to four different access levels, each allowing you to perform certain tasks. Table 4-7lists the default passwords and describes the access levels.

Table 4-7. SNMP Users and Default Passwords

	Default
Access Level	Password and	Description
	Community
	Name
		Special access for maintenance and
superuser	*********	diagnostics, to be used under the direction
		of a qualified technician. Reserved for
		internal use only,
manager	Manager	Full access to all configuration options,
		diagnostic tests and password control.
operator	Operator	Read/Write access to configuration and
		diagnostic features.
viewer	Viewer	Read-only access to configuration and
		diagnostic features.

The “Superuser” password is the highest level of access, followed by “Manager”, “Operator”, and “Viewer” in sequence. Each level allows you to also perform all operations available to the other levels below it. For example, if you log in under the “Operator” password, you can configure the system and perform diagnostic tests, or you can simply view the current system status and configuration data, which are the only tasks permitted under the “Viewer” password.

All passwords are case-sensitive for maximum security. For example, the system handles TechMan, TECHMAN, and Techman as three different passwords.
