Configuring SNMP Proxy Using Default Parameter Settings

Configuring SNMP Proxy Using Default Parameter Settings

This section describes how to configure Simple Network Management Protocol (SNMP) proxy using default parameter settings.

Usage Scenario

As shown in Figure 16-9, a middle-point device and the cabinet control unit (CCU) of a managed device are placed in an outdoor cabinet. The middle-point device needs to communicate management information between the network management station (NMS) and managed device, so that the NMS can manage the configurations and system software version of the managed device.
Figure 16-9 Networking diagram for configuring SNMP proxy using default parameter settings

If you want to use the NMS to manage the master device and the monitored device in a unified manner, deploy SNMP proxy on the master device. The NMS considers the master device and the monitored device as a virtual management unit, which significantly reduces the number of NEs to be managed by the NMS. This saves network management costs, monitors device running performance in real time, and improves service quality.

Configuring SNMP proxy using default parameter settings requires only one configuration command and is easy to implement. After you configure SNMP proxy, the middle-point device communicates with the managed device based on the default parameter settings used in the configuration command.

Pre-configuration Tasks

Before you configure SNMP proxy using default parameter settings, configure a routing protocol, so that the NMS, middle-point device, and managed device can communicate.

Precautions

In this type of SNMP proxy configuration, you do not need to configure SNMP on the managed device.

Before you configure SNMP proxy using default parameter settings, be sure to use the display default-parameter ccu command to check the default parameter settings to be used in the configuration command.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run set ccu target-host ip-address [ vpn-instance vpn-instance-name ] interface-type interface-number# ip vpn-instance ccu_private_vpn ipv4-family # interface GigabitEthernet0/1/1 *The interface type and number are the same as those specified in the set ccu target-host command.* undo shutdown ip binding vpn-instance ccu_private_vpn *If you do not specify vpn-instance in the set ccu target-host command, the system does not generate this configuration. ip address 192.168.1.1 255.255.255.0 # snmp-agent snmp-agent local-engineid 800007DB0338EBD9110010 # snmp-agent sys-info version all # snmp-agent usm-user v3 ccu_user1 # snmp-agent proxy community cipher %@%@'+bT@wzVD.mi#{(&1#)F,(_2.AP6,6jqT'HR$RGr*6!+(_5,d2S*L0[f+I"Nn@LfWf/;_>,(%@%@ remote-engineid 800007DB01192168001100 # snmp-agent proxy target-host proxy_host@ccu1 address udp-domain 192.168.1.100 udp-port 161 public-net params securityname cipher %$%$"2xeB+9a,#`[$;@|HTAV,(_q%$%$ v2c snmp-agent proxy target-host proxy_host@ems address udp-domain 10.13.49.200 udp-port 162 vpn-instance ccu_private_vpn params securityname cipher %$%$G3&4:EUvI2#\&"Jdqh)%,(_#%$%$ v2c # snmp-agent proxy rule proxy_rule_read@ccu1 read remote-engineid 800007DB01192168001100 target-host proxy_host@ccu1 params-in securityname cipher @%@%P2z76Gi&+1h,L;Q%1(/(,(_B@%@% v2c snmp-agent proxy rule proxy_rule_trap@ccu1 trap remote-engineid 800007DB01192168001100 target-host proxy_host@ems params-in securityname cipher @%@%E%>p!gzIhCNF:5><]@.:,(_p@%@% v2c snmp-agent proxy rule proxy_rule_write@ccu1 write remote-engineid 800007DB01192168001100 target-host proxy_host@ccu1 params-in securityname cipher @%@%p%JMH'M@>7==<1)xqqr%,(_a@%@% v2c # return

    SNMP proxy is configured using default parameter settings.

    After this step is performed, the middle-point device automatically generates configurations used to communicate with the managed device. An example of the configuration information is as follows:

  3. Run commit

    The configuration is committed.

Checking the Configurations

After configuring proxy using default parameter settings, check the configurations.

Run the display snmp-agent proxy community command to check SNMP proxy community information.

<HUAWEI> display snmp-agent proxy community
   Proxy Community name : %@%@#~CZ2lJB'0PP29IGZHM9,[RI%@%@
       Remote engine ID : 800007DB01192168001100 active
       Storage-type     : nonVolatile 

Run the display snmp-agent proxy rule command to check proxy rules for SNMP packets.

<HUAWEI> display snmp-agent proxy rule
   Proxy Rule name : proxy_rule_read@ccu1
       Type             : read
