瞻博网络 NETCONF RPC - 未返回数据

技术标签:
【中文标题】瞻博网络 NETCONF RPC - 未返回数据【英文标题】:Juniper NETCONF RPC - No data returned 【发布时间】:2021-04-07 16:10:03 【问题描述】:我正在尝试将自定义 XML RPC 发送到我的瞻博网络虚拟机。命令如下:
netconf-console --host 192.168.1.100 --port 830 --user xxxx --password xxxx --rpc junos-get-interfaces.xml
<nc:get-config xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0">
<nc:source>
<nc:running/>
</nc:source>
<nc:filter type="xpath" select="/interfaces">
</nc:filter>
</nc:get-config>
自定义 RPC 正在尝试过滤正在运行的配置,以仅检索接口节。但我收到以下回复:
<?xml version='1.0' encoding='UTF-8'?>
<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:junos="http://xml.juniper.net/junos/12.1R1/junos" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:f0b4fd48-fcb5-4e03-815b-961a19a9b525">
<data>
</data>
</rpc-reply>
但是,框上的 Interfaces 节下有配置。有什么想法吗?我也尝试在 netconf-console CLI 命令中使用 xpath,但它说服务器不支持它
netconf-console --host 192.168.1.100 --port 830 --user xxxx --password xxxx --get-config /native/interfaces 操作失败:MissingCapabilityError - 服务器不支持 [:xpath]
【问题讨论】:
【参考方案1】:XPath 不是 get-config 的有效过滤器类型。
<filter> — Enclose the <configuration> tag element. The mandatory type attribute indicates the kind of syntax used to represent the requested configuration elements; the
only
acceptable value is subtree.
https://www.juniper.net/documentation/en_US/junos/topics/reference/tag-summary/netconf-get-config.html
您可以改用过滤器类型子树,如下所述。
注意:GET-CONF 没有继承属性。如果您需要提取最终配置,即您正在使用“组”节,则需要使用 GET-CONFIGURATION。我将在下面的附加输出中显示差异。 https://www.juniper.net/documentation/en_US/junos/topics/reference/tag-summary/junos-xml-protocol-get-configuration.html
使用 get-conf 的 get-interfaces.xml 的内容
<get-config>
<source>
<running/>
</source>
<filter type="subtree">
<configuration>
<interfaces/>
</configuration>
</filter>
</get-config>
在目标主机上运行您的命令:
netconf-console --host 10.49.162.162 --port 830 --user root --password xxxx --rpc get-interfaces.xml
get-conf 的示例输出:
root@Ubuntu-Server:~# netconf-console --host 10.49.162.162 --port 830 --user root --password Embe1mpls --rpc get-interfaces.xml
<?xml version='1.0' encoding='UTF-8'?>

get-interfaces.xml 的内容使用 get-configuration 和继承
<get-configuration inherit="inherit">
<configuration>
<interfaces/>
</configuration>
</get-configuration>
get-configuration 的示例输出:[注意在同一主机上继承的所有附加接口]

注意:为了帮助找到过滤级别,可以在主机上运行“| display xml”命令来帮助识别正确的标签
root@vqfx-leaf-01> show configuration interfaces | display xml | display inheritance

【讨论】:
【参考方案2】:如果您尝试通过 netconf-console CLI 命令将--get-config
与--xpath
一起使用,您可以执行以下操作:
netconf-console --host 192.168.1.100 --port 830 --user xxxx --password xxxx --get-config --xpath /native/interfaces
