思科路由器的IP SLA特性集和配置实例
思科路由器上基本上都会内置了一个IP SLA特性集,下面通过一个实例来讲解这个特性集的作用。我们可以利用他产生实验所需的流量,其支持的流量类型很多,尤其是在IOS12.4T版本中,支持所需的各种流量!
不同的IOS版本中的SLA命令是不一样的阿,自己注意!~入12.4是IP SLA Monitor而12.4T则变为IP SLA了!
在12.3中,也许回事RTR。配置R1和R4。
R4的Telnet来源是yy245.4对R4与目的地是yy1.1对R1的, R1的是回复者。
测试将出现一次小时,并会不断的重复操作。
12.4T 配置实例
- r1(config)#ip sla 1
- r1(config-ip-sla)#tcp-connect 11.11.1.1 23 source-ip 11.11.245.4
- r1(config-ip-sla-tcp)#frequency ?
- r1(config-ip-sla-tcp)#frequency 3600
- r1(config)#ip sla schedule 1 life forever start-time new
- r1(config)#ip sla schedule 1 life forever start-time now
验证:
- r1#sh ip sla configuration
