1.简单网络管理协议(SNMP):
SNMP是一种应用程序层协议,已开发用于监视IP网络上的网络设备。它负责在网络设备之间交换管理信息。 SNMP协议由Internet体系结构委员会(IAB)定义。 SNMP协议是传输控制协议/ Internet协议(TCP / IP)协议套件的一部分。简单网络管理协议(SNMP)用于管理和监视网络设备。该协议从不同的网络元素收集信息,并且根据需要进行配置和修改。
2.系统记录协议(Syslog):
Syslog协议是用于消息记录的广泛使用的跨平台。 Syslog用于收集来自各种系统,设备,网络元素的系统事件信息,并将其存储在中央Syslog服务器中。这些存储的Syslog数据将进行分析,并在发生任何严重事件时发出警报。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。它主要收集各种设备日志并存储在Syslog服务器中,然后对其进行监视。简而言之,我们可以说它是负责在IP网络之间传输事件消息和发出警报的协议。
SNMP和Syslog之间的区别:
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. |
