cisco交換機設置同步日志本地時間的方法
分類： 系統運維
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
或通過NTP服務器時間同步：
Core-Switch-1#ntp server 192.168.0.254 key 8888 注：8888是指ntp服務器的Key值
Core-Switch-1#wr
Core-Switch-1#sh log
默認情況下日志消息不包括日期和時間戳。
service timestamps {debug | log } uptime
service timestamps {debug | log } datetime [mesc] [localtime] [show-timezone] [year]
debug 參數 在調試輸出時包括時間戳
log 參數 在每種日志消息中添加一個時間戳
uptime 在消息中包括路由器開機以來的時間
0w2d: #SYS-5-CONFIG_I : Configured from console by console
0w2d 開機后0周2天
datetime 顯示準確的日期和時間 UTC 格式 標準格式 MM DD HH:MM:SS
datetime后面可以跟一些參數
mesc 消息中包括毫秒信息
localtime 顯示基于本地配置的時區時間
show-timezone 輸出包括時區名稱
year 輸出包括年份信息
未設置時間前：
#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
設置后
#sh log
