    Dear Team,

    Following the below documents, If the network have STP, I need to use Bridge IMPVHA with IMPVHA off.
    But How can I setup Bridge IMPVHA with IMPVHA off? I cannot see the options for IMPVHA off.

    Thank you

    Hi Duc,

    HA can be toggled off via the impcfg menu.

    From the CLI on the gateway, type impcfg to access a text UI for modifying various configurations on the gateway.

    For a full impcfg functionality map, please see:

    The option for which you are seeking is within impcfg under: Manage SecureSphere Gateway > Manage interfaces and routes (for a bridge IMPVHA) > Toggle High Availability on a Bridge (Enabling HA will enable STP as well)

    Also, please see:
