N7K开启sla，没有icmp选项

[dinosaur0606]

The model is Nexus7000, version 6.1 (2), with sla responder and sla sender enabled, but there is no icmp echo in the sla process. What is the reason? If the device cannot support it, what other ways can it achieve the same function?

型号是Nexus7000，版本是6.1(2)，开启了sla responder和sla sender，但是sla进程中没有icmp-echo，是什么原因？如果设备无法支持的话，还能有什么办法实现相同的功能？

IP Service Level Agreement (SLA) is network performance-monitoring software that allows users to do service level monitoring, troubleshooting, and resource planning. In Cisco NX-OS Release 6.1(1), the IP SLA sender or responder support the following features: UDP jitter, UDP echo, TCP connect, SNMP, and reaction threshold traps. IP SLA does not require a license

release notes 6.2.x

IP service level agreement (IPSLA) features enhancements include PBR object tracking, ICMP, ECHO, and DNS.

从n7k的release notes中看，icmp是从nxos 6.2.x开始支持的,6.1是配置不了的，从Release notes中看6.1 bfd也有一些使用上的问题，也不太推荐使用。还是考虑一下升级一下nxos版本吧

参考如下链接，可以看到IPv4的IP SLAs ICMP Echo Operation从6.2(2)开始支持。升级升级到6.2(2)或之后的版本。
