Test RTT

Introducción

En este documento se describe cómo probar el Retraso de ida y vuelta (RTT) entre Cisco Video Communication Servers (VCS). Cada par de un clúster debe estar dentro de un salto de 15 ms (30 ms RTT) de cada uno de los otros VCS que se van a agregar al clúster.

Inicie sesión en un VCS miembro del clúster como raíz y haga ping al otro miembro del clúster con este comando:
```
ping -i 0.03 -s 4000 10.83.23.28
```

Deje que el ping se ejecute durante uno o dos minutos:
