VRA sending ICMP traffic

Viewed 106 times

Summary

The VRA is running a script every hour which tests connectivity to its peers. An administrator may notice that the VRA occasionally sends ICMP packets to other VRAs, locally or remotely.

Steps

The VRA's peers connectivity script is design to collect network-related information which allows Zerto to know the status of an environment's network when an issue is suspected to exist.
The script checks for the following:

1) MTU/Tracepath to other VRAs.
2) Traceroute to other VRAs
3) Ping in various sizes to other VRAs.
4) PMTU discovery packets
