permitted when vfabric is active.
● If the configured R_A_TOV value is not the same on both the sides of the port, then the port is
isolated. Ensure to configure the same R_A_TOV value on both the sides.
● You can change the R_A_TOV value only when vfabric is in inactive state. You can activate the vfabric
only by adding VLAN and fcmap configuration under the vfabric configuration view. Ensure to
configure the R_A_TOV before configuring the vlan, and fcmap in the vfabric configuration view.
