Methods and systems for port reachability are provided. The process obtains an identifier for ports of a broadcast domain to access storage space at a clustered storage system; sends a discovery request to the ports of the broadcast domain; receives a response to the discovery request from some or all the ports; places ports that responded to the discovery request to a first group that indicates that all ports within the group are reachable; and reports ports within the first group to a user to indicate which ports within the broadcast domain are reachable.
