If you ask vvr data replication bandwidth, you can run
#vxrlink -g <dg_name> -i 2 status <rlink_name>
you can work out easily the data rep bandwidth between 2 seconds time interval.
if I miss understood your question, please reply with more details of what is exactly the bandwidth info you after.

Good morning Sir!
Is there any available Bandwidth calculator? I just want to calculate the bandwidth for data transfer from One cluster to another.
Also would like to know the things needed or the requirements to calculate the bandwidth.
Thank you and best regards!

please read these technotes to see if they help
https://www.veritas.com/support/en_US/article.100022423 - "Using IPerf to measure available network bandwidth when troubleshooting VVR (Veritas Volume Replicator) performance issues"
https://www.veritas.com/support/en_US/article.100020987 - "Installing and running the FirstLook utility to gather performance data"
https://sort.symantec.com/public/documents/sf/5.1/aix/html/vvr_admin/ch03s05.htm - "Controlling the network bandwidth used for replication Understanding replication settings for a Secondary"
the actual VVR replication data rate is affected by many tactors and some of them are listed below
server avaialble resources
storage sub-system performance
VVR setup/ tunings
HBA/SAN/fibre etc tunings
VVR performance tuning is a very challenging task, if need further assistance, open a support case with Veritas support
make sure you gave the following data ready when open a support case
2. FirstLook reports (from both side of the servers)
