5.5.8. Points to Note

  • Common

    • By using this menu, all communication between different tenants becomes possible. At customer’s own risk, please do filtering by configuring firewall rule and routing etc. so that only minimum necessary communication is done.

    • Deletion of tenant connection and Enterprise Cloud 2.0 inter-connectivity (Shared network privilege) can be done from both source tenant and destination tenant.

    • Since there is a menu where rebooting occurs when disconnecting from the logical network, if you want to avoid restarting by operation from other tenants, please design such as connecting with dedicated resource.

    • Please do not connect with Logical Networks (eg. “common_function_gw_access_ (unique ID)” or connectable NATs) that Enterprise Cloud 2.0 Inter-Connectivity is able to connect to through the Common Function Gateway. Once connected, the services (Backup, NPT etc.) that are available via the Common Function Gateway will become available to other Tenants.

  • Connection from multiple tenants to the same logical network

    • By using this menu, you will be connected to the same L2 segment. In addition to unicast communication, communication propagating to the same L2 segment (such as BUM) is also propagated, so please do not connect multiple tenants when it becomes a security problem.

    • The source tenant who acquired the shared network privilege can check the other tenant IDs connected to the logical network, port name, description, tag etc from the port information. Please do not connect multiple tenants when it becomes a security problem.

  • Operetion

    • We may inform the failure information of the connection partner (opposite tenant) for early identification of the fault location and recovery.

    • When trouble is detected in our tenant of the connection source tenant or the connection destination tenant, NTTCom will not notify failure information to the connection partner (opposite tenant).
