Chapter 9 Network Management
Confidential and Proprietary Information of ZTE CORPORATION 227
An NMS collects data by polling the agents that reside in
managed devices. Agents in managed devices can report
errors to NMSs at any time before NMSs poll them. These
errors are called traps. When a trap occurs to a device, the
NMS can be used to query the device (suppose it is reachable)
and obtain more information.
All variables in the network are stored in MIB. SNMP monitors
network device status by querying the related object values in
the agent MIB. ZXR10 2920/2928/2952 implements the
standard MIB defined in rfc1213, rfc1493, rfc2674 and rfc2819.
Configuring SNMP
This topic describes the configuration of SNMP.
For the configuration of SNMP, perform the following steps.
1. To create communication name and set access authority,
use command create community in SNMP config mode.
This is shown in
Table 372.
TABLE 372 CREATE COMMUNITY COMMAND
Format Mode Function
create community
SNMP config This creates
communication
name and set
access authority
Result: This creates communication name and set access
authority
f Community string offers a user confirmation mechanism
for remote network administrators to configure switches.
The “public” indicates that switch only allows for read
only access, while “private” indicates that the read/write
authority to the switch is permitted.
f If community string created with this command already
exists, newly created string overwrites the original one.
2. To create a view and specify whether the view contains a
mib subtree, use command create view in SNMP config
mode. This is shown in
Table 373.
TABLE 373 CREATE VIEW COMMAND
Format Mode Function
create view SNMP config This creates a view
Result: This creates a view and specifies whether the view
contains a mib subtree.
