Calculate your round-trip time (RTT) for SnapMirror Synchronous
Run the cluster peer ping command, where the originating-node is the node that hosts the source volume of the relationship and the destination-node is the node that hosts the destination volume of the relationship.
cluster::> cluster peer ping -originating-node sti8080-475 -destination-node sti8080-477
Node: sti8080-475 Destination Cluster: C2_sti8080-477_cluster
Destination Node IP Address Count TTL RTT(ms) Status
---------------- ----------- ----- ---- ------- -------------------------
sti8080-477 172.26.145.10 1 64 0.452 interface_reachable
sti8080-477 172.26.145.12 1 64 0.352 interface_reachable
For intracluster relationships, you can run the network ping command in a similar way.
cluster::> network ping -node sti8080-477 -destination sti8080-475 -show-detail
