Port requirements for communicating with the 7-Mode Transition Tool

The 7-Mode Transition Tool communicates with the 7-Mode system and the cluster over certain ports. You must ensure that these ports on the 7-Mode system and the cluster are open to allow communication with the 7-Mode Transition Tool.

Ports that must be open on the 7-Mode systems

The 7-Mode Transition Tool communicates with the 7-Mode systems by using HTTPS on port 443.

The following ports are required by the cluster to communicate with the 7-Mode systems for SnapMirror replication:

  • 10565/TCP

  • 10566/TCP

  • 10567/TCP

  • 10568/TCP

  • 10569/TCP

  • 10670/TCP

Ports that must be open on the cluster

The 7-Mode Transition Tool communicates with the cluster by using HTTPS on port 443.

The following ports are required by the 7-Mode systems to communicate with the cluster for SnapMirror replication:

  • 10565/TCP

  • 10566/TCP

  • 10567/TCP

  • 10568/TCP

  • 10569/TCP

  • 10670/TCP

  • 11105/TCP

Additionally, the 7-Mode Transition Tool performs a ping operation from the intercluster LIFs to the data copy IP address of the 7-Mode system to verify reachability.

Ports that must be open on the 7-Mode Transition Tool

Port 8444 of the 7-Mode Transition Tool must be open for the web interface.

To transition netgroups and CIFS local users and groups, the following requirements must be met:

  • Port 8088 of the 7-Mode Transition Tool must be available.

    For an alternative to port 8088, you must change the port specified by the tool.http.port parameter in the transition-tool.conf file of the 7-Mode Transition Tool installation directory.

    Note You must restart the 7-Mode Transition Tool service after changing the port in the configuration file.

  • Each node in the cluster must have at least one data LIF configured for the target SVM.

  • All SVM data LIFs must be able to communicate with the 7-Mode Transition Tool port 8088 or the port specified by the tool.http.port parameter in the transition-tool.conf file.

    Note You must verify that firewalls do not block this traffic.
