H3C路由器tracert命令怎麼開啓
你想要實現的是使用tracert命令的時候能夠顯示出路由器那一跳的地址吧,命令很簡單,下面一起來看看吧!
[H3C]ip ttl-expires enable
[H3C]ip unreachables enable
你路由器使用了這條命令後tracert的時候就能看到這個路由器那一跳的地址了。
H3C路由器tracert超時解決辦法
單位的H3C路由器和交換機上,tracert總是超時。
但是可以正常上網或者ping到目標。
後來查找資料,找到了解決辦法。
解決方法:
ip ttl-expires enable ip unreachables enable
(官方說法這兩條命令默認開啓,可能跟版本有關,有的默認未開啓。)
官方對這兩條命令解釋是:
ip ttl-expires enable命 令用來開啓設備的`ICMP超時報文的發送功能。undo ip ttl-expires命令用來關閉設備的ICMP超 時報文的發送功能。(缺省情況下,ICMP超時報文發送功能處於開啓狀 態。)
需要注意的是,關閉ICMP超時報文發送 功能後,設備不會再發送“TTL超時”ICMP差 錯報文,但“重組超時”ICMP差錯報文仍會正常發送。
ip unreachables enable命 令用來開啓設備的ICMP目的不可達報文的發送功能。undo ip unreachables命令用來關閉設備的ICMP目 的不可達報文的發送功能。(缺省情況下,ICMP目的不可達報文發送功 能處於關閉狀態。)
H3C基於源地址策略路由實例
system-view
System View: return to User View with Ctrl+Z.
