1 简介

本文档介绍了SNMP功能典型配置举例。

2 配置前提

本文档不严格与具体软、硬件版本对应，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。

本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。

本文档假设您已了解SNMP特性。

3 SNMPv1/SNMPv2c配置举例

3.1 组网需求

如图1所示，服务器作为NMS通过SNMPv1/SNMPv2c协议对设备进行配置文件备份，并且当设备出现故障时能够主动向NMS发送告警信息。 图1 SNMPv1/v2c功能典型配置组网图

3.2 使用版本

本举例是在S5820V2_5830V2-CMW710-R2418P01版本上进行配置和验证的。

3.3 配置注意事项

• • •

SNMPv2c与SNMPv1配置方法完全一致，本举例中以配置SNMPv2c为例进行介绍。 用户在设备和NMS上配置的SNMP版本号和团体字必须一致，否则，NMS无法对设备进行管理和维护。

不同厂商的NMS软件配置方法不同，本配置举例中，以IMC PLAT 7.0 (E0202)为例进行介绍。

3.4 配置步骤

3.4.1 设备的配置

# 设置Agent使用的SNMP版本为v2c、只读团体名为readtest，读写团体名为writetest。

system-view

[Agent] snmp-agent sys-info version v2c [Agent] snmp-agent community read readtest [Agent] snmp-agent community write writetest

# 设置设备的联系人和位置信息，以方便维护。

[Agent] snmp-agent sys-info contact Mr.Wang-Tel:3306

[Agent] snmp-agent sys-info location telephone-closet,3rd-floor

# 设置允许向NMS发送告警信息，使用的团体名为traptest。

[Agent] snmp-agent trap enable

[Agent] snmp-agent target-host trap address udp-domain 192.168.100.4 params securityname traptest

3.4.2 NMS的配置

# 增加设备

登录进入IMC管理平台，选择“资源”页签，单击导航树中的[增加设备]菜单项，进入增加设备配置页面。 • •

设置设备的主机名或IP地址为“192.168.100.68”； 其它参数采用缺省值。

图2 增加设备配置页面

# 在该页面中单击“配置SNMP参数”按钮，展开配置SNMP参数页面，单击“设置”，在弹出的对话框中设置如下内容。 • • • •

设置参数类型为“SNMPv2c”； 设置只读团体字为“readtest”； 设置读写团体字为“writetest”；

其它参数采用缺省值，并单击<确定>按钮完成操作。

图3 SNMP参数设置页面

# 在“增加设备”页面单击<确定>按钮，iMC返回增加设备成功信息。 图4 增加设备成功页面

# 增加设备成功后，用户即可通过iMC（NMS）对设备进行配置、管理和维护。不同NMS管理软件配置不同，关于NMS的详细配置，具体请参考NMS的相关手册。

3.5 验证配置

(1) Agent向NMS发送Trap信息

# 完成以上配置之后，在设备上的某个空闲接口执行shutdown或undo shutdown操作，设备会向NMS发送接口状态改变的Trap。

# 在“告警>告警浏览>全部告警”页面中可以查看上述Trap信息。

(2) 在NMS上备份Agent配置文件

# 在“资源>设备视图”页签点击“Agent”，进入如图6页面，点击右侧的“备份配置文件”。 图6 备份配置文件

# 操作成功后会显示如下页面。 图7 备份配置文件成功

3.6 配置文件

#

snmp-agent

snmp-agent community write writetest snmp-agent community read readtest

snmp-agent sys-info contact Mr.Wang-Tel:3306

snmp-agent sys-info location telephone-closet,3rd-floor snmp-agent sys-info version v2c v3 snmp-agent trap enable arp

snmp-agent target-host trap address udp-domain 192.168.100.4 params securityname traptest #

4 SNMPv3配置举例

4.1 组网需求

如图8所示，服务器作为NMS通过SNMPv3协议对设备进行配置文件备份，提供更高的安全性，并且当设备出现故障时能够主动向NMS发送告警信息。 图8 SNMPv3功能典型配置组网图

4.2 使用版本

本举例是在S5820V2_5830V2-CMW710-R2418P01版本上进行配置和验证的。

4.3 配置注意事项

• • • •

用户需要分别对设备和NMS配置SNMP功能，设备与NMS的SNMP配置必须一致，否则，NMS无法对设备进行管理和维护。

不同厂商的NMS软件配置方法不同，本配置举例中，以IMC PLAT 7.0 (E0202)为例进行介绍。

SNMPv3接收Trap报文的目的主机的安全参数要使用设备已配置的v3用户，且安全模型要一致。

SNMPv3的认证密码和加密密码以密文形式保存在配置文件中，密文密码由明文密码和本设备的引擎ID计算后生成。如果要将两台设备的认证密码和加密密码配置为相同值，建议使用明文密码在两台设备上分别手工配置，不要直接拷贝配置文件中的相关配置。因为两台设备的引擎ID不同，会导致密文密码相同，而对应的明文密码不同。

4.4 配置步骤

4.4.1 设备的配置

# 设置Agent使用的SNMP版本为v3。

system-view

[Agent] snmp-agent sys-info version v3

# 创建MIB视图，名字为mibtest，包含internet子树（OID为“1.3.6.1”）所有对象。

[Agent] snmp-agent mib-view included mibtest 1.3.6.1

# 创建SNMPv3组managev3group，并配置与该组绑定的SNMPv3用户与NMS建立连接时，均进行认证和加密，NMS可以对设备进行读写的视图均为mibtest。

[Agent] snmp-agent group v3 managev3group privacy read-view mibtest write-view mibtest notify-view mibtest

# 设置SNMPv3用户名为managev3user，认证算法为SHA-1，明文认证密码为123456TESTauth&!，加密算法为AES，明文加密密码是123456TESTencr&!。

[Agent] snmp-agent usm-user v3 managev3user managev3group simple authentication-mode sha 123456TESTauth&! privacy-mode aes128 123456TESTencr&!

# 开启SNMP告警功能。

[Agent] snmp-agent trap enable

# 设置接收SNMP告警信息的目的主机IP地址，即NMS的IP地址，配置安全认证参数为managev3user。

[Agent] snmp-agent target-host trap address udp-domain 192.168.100.4 params securityname managev3user v3 privacy

4.4.2 NMS的配置

# 登录iMC，选择“系统管理”页签，单击导航树中的[资源管理/SNMP模板]菜单项，进入SNMP模板配置页面，在该页面中单击<增加>按钮，进入增加SNMP模板配置页面。 • • • • • •

配置SNMP模板的名称为SNMPv3。

选择参数类型为SNMPv3 Priv-Aes128 Auth-Sha。 配置SNMP用户名为managev3user。 明文认证密码为123456TESTauth&!。 明文加密密码为123456TESTencr&!。

其它参数采用缺省值，并单击<确定>按钮完成操作。

# 进入SNMP参数设置页面配置SNMP参数 • •

选择“从已有的SNMP参数模板中选取”。 选择名称为“SNMPv3”的SNMP模板。
