SNMP采用UDP 161端口接收和发送请求,162端口接收trap,执行SNMP的设备缺省都必须采用这些端口。SNMP消息全部通过UDP端口161接收,只有Trap信息采用UDP端口162。 1.5、Snmp版本 SNMP 目前共有 3 个版本,分别为 v1、v2 和 v3,说明如下: SNMP v1:是 SNMP 协议的最初版本,在 1988 年被制定,并被 Internet 体系结构委...
Protocol dependencies Typically, SNMP usesUDPas its transport protocol. The well known UDP ports for SNMP traffic are 161 (SNMP) and 162 (SNMPTRAP). It can also run overTCP,Ethernet,IPX, and other protocols.ATMuses SNMP as itsILMI(Integrated Local Management Interface) protocol. Wireshark The...
这张图表明,发送到应用层的UDP数据报的数量(udpInDatagrams)就是从IP层送到UDP层的UDP数据报的数量,当然udpInError和udpNoPorts也类似。同样,发送到IP层的UDP数据报的数量(udpOutDatagrams)就是从应用层发出的UDP数据报的数量。这表明udpInDatagram不包括udpInError和udpNoPorts。 在深入讲解MIB的时候,这些Case图...
SNMP Ports SNMP ports are SNMP communication endpoints, and SNMP messages are transmitted through UDP. Generally, UDP ports 161 and 162 are used. In some scenarios, Transport Layer Security (TLS) or Datagram Transport Layer Security (DTLS) is used. The following table shows the port usage. ...
SNMP uses UDP ports 161 for the agent and 162 for the manager. The Manager may send Requests from any available ports (source port) to port 161 in the agent (destination port). The agent response will be given back to the source port. The Manager will receive traps on port 162. The ...
SNMP采用UDP 161端口接收和发送请求,162端口接收trap 一、SNMP简单概述 1.1、什么是Snmp SNMP="Simple Network Management Protocol"="简单网络管理协议"。 SNMP属于TCP/IP五层协议中的应用层协议,主要用于网络设备的管理。 由于SNMP协议简单可靠 ,受到了众多厂商的欢迎,成为了目前最为广泛的网管协议。
