Basic Configuration Of Snmp - Zte ZXR10 2900 Series User Manual

� MIB: Management Information Base
� SMI: Structure of Management Information
� SNMP: Simple Network Management Protocol
They offer the means to collect network management information
from network devices. SNMP also enables devices to report prob-
lems and errors to network management stations. Any network
administrator can use SNMP to manage switches. ZXR10 2900
supports SNMPv1 v2c and v3(v3 strengthens SNMP management
security based on v1 and v2c).
SNMP adopts the "Management process—Agent process" model to
monitor and control all types of managed network devices. The
SNMP network management needs three key elements:
1. Managed devices, which can communicate over the Internet.
Each device contains an agent.
2. NMS The network management process shall be able to com-
municate over the Internet.
3. The protocol used for the exchange of management informa-
tion between the switching agent process and the NMS, that
is, SNMP.
An NMS collects data by polling the agents that reside in the man-
aged devices. The agents in the managed devices can report errors
to NMSs at any time before the 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 infor-
mation. Snmp v2c and v3 also support inform (a SNMPv2 Trap that
need response) to inform abnormal events to NMS. If receives in-
form message NMS will send a acknowledgement packet to switch.
If switch hasn't received acknowledgement packet from NMS in a
period time it will resend the original inform message twice.
All variables in the network are stored in the MIB. SNMP monitors
network device status by querying the related object values in the
agent MIB. ZXR10 2900 implements the standard MIB and private
MIB defined in rfc2233, rfc1493, rfc2665 and rfc2819.

Basic Configuration of SNMP

The SNMP configuration includes the following contents:
Command
config snmp
zte(cfg)#
create community
zte(cfg-snmp)#
<string>{public | private}
create view <string>[{incl
zte(cfg-snmp)#
ude | exclude}<mib-oid>]

This enters SNMP
management mode.
This creates
communication name
and set the access
authority.
This creates a view
name. The default
setting is include, which
includes mib subtree.
