Cisco并不难，主要有些人没有接触的机会，如果你经常管理cisco设备，你会发现其实就那几步，不过也有不少网友不知道cisco交换机时间设置时间怎么设置。其实步骤并不难，下面小编给大家介绍一下具体操作办法，供大家参考!

cisco交换机时间设置时间具体操作

将CISCO6509配置为标准时间服务器

ntp server 192.168.0.101

查询当前的时间

Cisco6509#show clock

00:09:13.643 PDT Tue Jun 30 2009

配置一个北京时区，随意取名

clock timezone Beijing 8

再查询一下，已经同步过来了

CISCO6509#show clock

15:10:00.239 Beijing Tue Jun 30 2009

设定硬件时钟为权威NTPserver

(config)#clock calendar-valid

调整时间

#clock set 15:00:00 30 jun 2009

当前时钟为

#show clock

15:15:10.705 Beijing Tue Jun 30 2009

当前硬件时钟为

#show calendar

14:37:59 Beijing Tue Jun 30 2009

NTP源为vlan2

(config)#ntp source vlan 2

将同步其他时间去除

no ntp server 10.20.0.103

将硬件时钟与当前clock同步

#clock update-calendar

查看当前clock时间

#show clock

.15:47:57.558 Beijing Tue Jun 30 2009

查看当前硬件时钟

#show calendar

15:48:00 Beijing Tue Jun 30 2009

配置系统debug记录的时间格式

(config)#service timestamps debug datetime localtime

配置系统日志记录时间格式

(config)#service timestamps log datetime localtime

设置与其他时间服务器同步

(config)#ntp server 192.168.0.102

设置为第一级ntp服务器

(config)#ntp master 1

允许更新硬件时钟(不必须)

(config)#ntp update-calendar

查看的ntp设置的命令

sh clock detail

sh ntp sta

sh ntp ass

sh ntp ass detail

----配置命令

ntp authentication-key 1 md5 xx

ntp source Loopback0

ntp server 10.10.10.1 key 1

配置方法:

// router 7206

conf t

ntp source FastEthernet0/1 //指定更新源地址,覆盖ntp server中的配置

ntp update-calendar //设备如带有硬件时钟,同时更新硬件时钟

ntp server 202.155.248.218 source FastEthernet0/1 //指定更新目的地址,香港,并指定更新源接口为f0/1.

int f0/1

ntp enable

这时你应该已经获得了时间，但是注意，时区是否正确，默认为格林威治时间，如想改为北京时间，下面这步是必不可少的。

Core-Switch-1#show clock

Core-Switch-1#show ntp status

Core-Switch-1#conf t

Core-Switch-1(config)# clock timezone GMT +8

Core-Switch-1(config)#service timestamps debug datetime msec localtime show-timezone

Core-Switch-1(config)#service timestamps log datetime msec localtime show-timezone

Core-Switch-1(config)#exit

Core-Switch-1# clock set 13:51:00 Sep 7 2011

或通过NTP服务器时间同步：

Core-Switch-1#ntp server 192.168.0.254 key 8888 注：8888是指ntp服务器的Key值

Core-Switch-1#wr

Core-Switch-1#sh log

默认情况下日志消息不包括日期和时间戳。

service timestamps {debug | log } uptime

service timestamps {debug | log } datetime [mesc] [localtime] [show-timezone] [year]

debug 参数 在调试输出时包括时间戳

log 参数 在每种日志消息中添加一个时间戳

uptime 在消息中包括路由器开机以来的时间

0w2d: #SYS-5-CONFIG_I : Configured from console by console

0w2d 开机后0周2天

datetime 显示准确的日期和时间 UTC 格式 标准格式 MM DD HH:MM:SS

datetime后面可以跟一些参数

mesc 消息中包括毫秒信息

localtime 显示基于本地配置的时区时间

show-timezone 输出包括时区名称

year 输出包括年份信息

未设置时间前：

#sh log

4w0d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/6, changed state to up

4w0d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/6, changed state to down

4w0d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/6, changed state to up

4w1d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/5, changed state to down

4w1d: %LINK-3-UPDOWN: Interface FastEthernet0/5, changed state to down

4w1d: %LINK-3-UPDOWN: Interface FastEthernet0/5, changed state to up

4w1d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/5, changed state to up

4w1d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/3, changed state to down

4w1d: %LINK-3-UPDOWN: Interface FastEthernet0/3, changed state to down

4w1d: %LINK-3-UPDOWN: Interface FastEthernet0/3, changed state to up

4w1d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/3, changed state to up

设置后

#sh log
