1.简单网络管理协议(SNMP):
SNMP 是一种应用层协议,已开发用于通过 IP 网络监控网络设备。它负责在网络设备之间交换管理信息。 SNMP 协议由 Internet Architecture Board (IAB) 定义。 SNMP 协议是传输控制协议/互联网协议 (TCP/IP) 协议套件的一部分。简单网络管理协议 (SNMP) 用于管理和监控网络设备。该协议从不同的网络元素收集信息,并根据需要进行配置和修改。
2. 系统日志协议(Syslog):
Syslog 协议是一种广泛使用的跨平台消息记录协议。 Syslog 用于从各种系统、设备、网络元素收集系统事件信息,并将其存储在中央 Syslog 服务器中。这些存储系统日志数据被分析并在发生任何关键事件时发出警报。此 Syslog 协议在 RFC 3164 中定义,但最初由 Eric Allman 编写。此 Syslog 协议旨在帮助传输这些事件消息。主要是收集各种设备日志并存储在Syslog服务器中,然后对其进行监控。因此,我们可以简单地说它是负责跨 IP 网络传输事件消息和警报的协议。
SNMP 和 Syslog 的区别:
Serial Number | SNMP | SYSLOG |
---|---|---|
1. | SNMP protocol refers Simple Network Management Protocol. | SYSLOG protocol refers to System Logging Protocol. |
2. | It monitors the network devices over IP networks. | It transmits the log messages to Syslog server and monitores it. |
3. | It traps are shared in binary format. | It events are shared in Plain text format. |
4. | It is an active protocol. | It is an passive protocol. |
5. | It is secure. | It is not secure. |
6. | It is referred to get real time information. | It is referred to acquire historical data. |
7. | It is used to alert on critical actions like mentioned (Hot Stanby Router Protocol) HSRP state changes. | It allows to dig dipper to figure out why that (Hot Stanby Router Protocol) HSRP state change occured. |
8. | By the help of SNMP end device configuration is possible. | By the help of Syslog set end device configuration is not possible. |
9. | It uses UDP port number 161 and 162. | It uses TCP/UDP port number 514. |
