SNMP Configuration
This chapter explains SNMP Configuration menu 22.
28.1  About SNMP
Simple Network Management Protocol is a protocol used for exchanging management 
information between network devices. SNMP is a member of the TCP/IP protocol suite. Your 
Prestige supports SNMP agent functionality, which allows a manager station to manage and 
monitor the Prestige through the network.  The Prestige supports SNMP version one 
(SNMPv1) and version two c  (SNMPv2c). The next figure illustrates an SNMP management 
operation. SNMP is only available if TCP/IP is configured.
Figure 147   SNMP Management Model
An SNMP managed network consists of two main components: agents and a manager. 
An agent is a management software module that resides in a managed device (the Prestige). 
An agent translates the local management information from the managed device into a form 
compatible with SNMP. The manager is the console through which network administrators 
perform network management functions. It executes applications that control and monitor 
managed devices.  
						

							Prestige 334 User’s Guide
271 Chapter 28 SNMP Configuration
The managed devices contain object variables/managed objects that define each piece of 
information to be collected about a device. Examples of variables include the number of 
packets received, node port status etc. A Management Information Base (MIB) is a collection 
of managed objects.  SNMP allows a manager and agents to communicate for the purpose of 
accessing these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The 
manager issues a request and the agent returns responses using the following protocol 
operations:
1Get - Allows the manager to retrieve an object variable from the agent. 
2GetNext - Allows the manager to retrieve the next object variable from a table or list 
within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table 
from an agent, it initiates a Get operation, followed by a series of GetNext operations. 
3Set - Allows the manager to set values for object variables within an agent. 
4Trap - Used by the agent to inform the manager of some events.
28.2   Supported MIBs
The Prestige supports RFC-1215 and MIB II as defined in RFC-1213 as well as ZyXEL 
private MIBs. The focus of the MIBs is to let administrators collect statistic data and monitor 
status and performance.
28.3  SNMP Configuration
To configure SNMP, select option 22 from the main menu to open Menu 22 — SNMP 
Configuration as shown next.  The “community” for Get, Set and Trap fields is SNMP 
terminology for password.

The following table describes the SNMP configuration parameters.
28.4  SNMP Traps 
The Prestige will send traps to the SNMP manager when any one of the following events 
occurs:
Menu 22 - SNMP Configuration
       SNMP:
         Get Community= public
         Set Community= public
         Trusted Host= 0.0.0.0
         Trap:
           Community= public
           Destination= 0.0.0.0
Press ENTER to Confirm or ESC to Cancel:
Table 89   Menu 22 SNMP Configuration
FIELDDESCRIPTION
SNMP:
Get CommunityTy p e  t h e  Get Community, which is the password for the incoming Get- and 
GetNext requests from the management station.
Set CommunityTy p e  t h e  Set community, which is the password for incoming Set requests from 
the management station. 
Trusted HostIf you enter a trusted host, your Prestige will only respond to SNMP messages 
from this address. A blank (default) field means your Prestige will respond to all 
SNMP messages it receives, regardless of source.
Trap:
CommunityType the trap community, which is the password sent with each trap to the SNMP 
manager. 
DestinationType the IP address of the station to send your SNMP traps to.
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to confirm or ESC 
to cancel” to save your configuration or press [ESC] to cancel and go back to the previous screen.

System Information and
Diagnosis
This chapter covers the information and diagnostic tools in SMT menus 24.1 to 24.4.
These tools include updates on system status, port status, log and trace capabilities and 
upgrades for the system software. This chapter describes how to use these tools in detail.
Type 24 in the main menu to open Menu 24 – System Maintenance, as shown in the 
following figure.
Figure 149   Menu 24 System Maintenance
29.1  System Status
The first selection, System Status gives you information on the status and statistics of the 
ports, as shown next Figure 150 . System Status is a tool that can be used to monitor your 
Prestige. Specifically, it gives you information on your ADSL telephone line status, number of 
packets sent and received.
To get to System Status, type 24 to go to Menu 24 — System Maintenance. From this menu, 
type 1. System Status. There are two commands in Menu 24.1 — System Maintenance — 
Status. Entering 1 resets the counters; [ESC] takes you back to the previous screen.
The following table describes the fields present in Menu 24.1 — System Maintenance — 
Status which are read-only and meant for diagnostic purposes.

29.3  Log and Trace
There are two logging facilities in the Prestige. The first is the error logs and trace records that 
are stored locally. The second is the syslog facility for message logging.
29.3.1  Syslog Logging
The Prestige uses the syslog facility to log the CDR (Call Detail Record) and system messages 
to a syslog server. Syslog and accounting can be configured in Menu 24.3.2 — System 
Maintenance - Syslog Logging, as shown next.
Figure 154   Menu 24.3.2 System Maintenance : Syslog Logging
You need to configure the syslog parameters described in the following table to activate syslog 
then choose what you want to log.
Your Prestige sends five types of syslog messages. Some examples (not all Prestige specific) 
of these syslog messages with their message formats are shown next:
