Establishing The Configuration Task - Huawei Quidway S9300 Configuration Manual - Network Management

Quidway S9300 Terabit Routing Switch
Configuration Guide - Network Management
Station synchronizes the alarm with the alarm log on the switch to avoid loss of the failure
information.

1.18.1 Establishing the Configuration Task

Before sending traps in Inform mode, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This can help you complete
the configuration task quickly and accurately.
1.18.2 (Optional) Enabling the switch to Send Specified Alarms to the NM Station
1.18.3 (Optional) Enabling the switch to Send an Alarm Message of a Specified Feature to the
NM Station
1.18.4 Configuring the Destination Host of Informing Messages
This part describes how to configure the destination address (IP address of the NM Station) for
trap messages.
1.18.5 (Optional) Configuring Global Parameters for the Informing Mode
If the current network is unstable, you need to increase the timeout period for confirming the
alarm. At the same time, you need to increase the retransmission times and the maximum number
of pending alarms.
1.18.6 (Optional) Configuring the Parameters for the Informing Mode
1.18.7 (Optional) Configuring the Logging Function for the Informing Mode
If the switch and the destination host cannot communicate because of a link failure, the switch
no longer sends Inform messages to send traps but keeps generating trap logs. When the link
recovers, the switch updates trap logs recorded during the link failure to the host destination.
1.18.8 Checking the Configuration
After sending traps in Inform mode is enabled, you can view corresponding parameters.
1.18.1 Establishing the Configuration Task
Before sending traps in Inform mode, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This can help you complete
the configuration task quickly and accurately.
Applicable Environment
In SNMP, a managed device propagates the alarms to the NM Station in two modes:
l
l
The Informing mode supports alarm logging. When the communication between the NM Station
and the managed device fails, the object can log the alarm. After the fault is rectified, the NM
Station synchronizes the alarm with the alarm log on the managed device to avoid failure
information loss.
The Informing mode applies to the large-scale network as well as the scenario where high
reliability of the NM Station is required.
Issue 03 (2010-09-20)
Trap: In this mode, the NM Station need not return acknowledgment messages. This mode
is not reliable.
Inform: In this mode, the NM Station must return acknowledgment messages. If receiving
no acknowledgment messages in a certain period, the managed device re-propagates the
alarms. This mode is of higher reliability.
