when you want to connect 2 FC switches that are separated by a network into a single fabric thru a gateway. By defaults, switch ports initialize links using ELP mode 1. However, gateways expect ELP mode 2 (ie ISL R_RDY mode on) therefore E-ports on both switches must be set to ISL R_RDY mode to on.
Hope this helps.

ISL R_RDY mode may be enabled in case of ISL distance.This can be set thorugh portCfgISLMode command. But through portcfgshow we can check whether it is enabled or not.Keeping the distance in mind we have to set it.
